Re: [MapServer-users] multiple shapepaths

[Lime, Steve D (MNIT) via MapServer-users]

IMHO, if you do a SHAPEPATH at the layer level then you might as well just add 
the full-path to the DATA element. You’re not really gaining anything with the 
additional complexity. Did the idea of using runtime variables not pan out?

How about a shapepath at the layer level? I am combining 20 years of working 
with old maps in three (or four :-)) different countries (Netherlands, Germany 
and Flemish and Walloon Belgium), all in their own formats, projections, 
directories an servers. It would help to keep my applications (and my mind) 
clear if I could use the appropriate shapepaths. And as to portability, it is 
essential to use relative paths. Just try to move a website to a new server 
with a differently named filesystem, if all paths are hard coded.

Re: [MapServer-users] Who remembers the truth about antialiasing?

[Lime, Steve D (MNIT) via MapServer-users]

Looking at the code, the keyword is still in place in 8.0. It is recognized in 
the STYLE object but is silently ignored inside a LABEL object. I didn't check 
rendering code specifically to see what true vs false values affected. So, I 
think your conclusions are correct.

Subject: [MapServer-users] Who remembers the truth about antialiasing?

Hi,

When Mapserver started to use AGG renderer everybody thought that antialiasing 
is not only the strength of the library but also the only way AGG can render. 
See https://mapserver.org/output/agg.html and 
https://lists.osgeo.org/pipermail/mapserver-users/2007-September/025467.html.
But then some Mapserver users noticed that AGG (and Mapnik) can also do aliased 
rendering at least for lines. Discussion on the mailing list 
https://lists.osgeo.org/pipermail/mapserver-users/2017-October/080278.html 
yielded a GitHub issue https://github.com/MapServer/MapServer/issues/5508 and a 
commit 
https://github.com/erik-h11/mapserver/commit/9ca99e763738fba7acaea6089afb5b5b7cd6e699.

However, the Mapserver documentation is unclear 
https://mapserver.org/mapfile/style.html#mapfile-style-antialias. I understand 
it so that setting antialias has not been functional since 7.0, and in 8.0 the 
whole keyword was removed.

"ANTIALIAS [true|false]
Removed in version 8.0: GD support was removed in 7.0 (and this mapfile 
parameter was removed in 8.0)
Should antialiasing be applied to the style. For line rendering only. Default 
is false."

My conclusions at the moment are:

  *   ANTIALIAS true|false does work in STYLE. It affects only lines, but 
polygon outlines are also lines. The default is TRUE.
  *   ANTIALIAS does not have an effect in other places: LABEL and SYMBOL. They 
are always antialiased.

If that is correct I may have a try with improving the documentation.

I started to experiment with antialias because I was not very satisfied with a 
very simple map that has only lines and labels. For my mind the lines on that 
map look better without antialiasing. Unfortunately I could not do anything for 
the labels. Especially dashes turn out light grey and blurry. The font is 
truetype, Vera, and the text color in the mapfile is pure black. All hints for 
making labels sharper are welcome.

Almost there. There are additional migration examples in:

I wrote wrapper functions for the old ms_new... functions, and can create that 
way a new mapObj called $oMap.

The "set" function has been  renamed  to "__set" : not 
$oMap->set("maxsize",6020), but: ;$oMap->__set("maxsize",6020);

Layers can be declared as before:  $layer = $oMap->getLayer(1).

Metadata have to be set as follows:

Not: $layer->setMetadata("...","..."); but: $layer->metadata->set("...","...")

However, I cannot set the metadata of the mapObj: 
$oMap->metadata->set("...","...") gives: "Undefined array key "metadata""

Any idea?

all of your PHP scripts (that leverage MapServer objects and functions) must 
now always first include the generated mapscript.php file containing MapServer

Hello Steve


Thank you for your response,
we would have expected that too.

with wms 1.1 the service response is the same.

with this metadata "wms_timeextent" "2005/2022"
the service response is:

http://localhost:/local/?SERVICE=WMS=1.1.0=GetMap=image/png=true=ch.swisstopo.lubis-bildstreifen=EPSG:2056==860=600=242,105,285,135=2022-01-01/2022-12-31

 
 
msWMSApplyTime: WMS server error. Time value(s) 2022-01-01/2022-12-31 given is 
invalid or outside the time extent defined (2005/2022).



The only work-around we found so far is to set the time-range in the metadata 
with a date precision of day:
"wms_timeextent" "2005-01-01/2022-12-31" but then in the getcap we would have 
this information:

2005-01-01/2022-12-31

which is not representing the real nature of this dataset, the time resolution 
here should be a year.

Does WMS 1.1 behave the same? I suppose it comes down to how 2022 is 
interpreted as part of a range, I would have expected it would mean any date in 
that year. Sounds like it's behaving like strictly less than 2022-01-01. What 
happens if you set the range using full dates, so something like: 
20050101/20221231?

The time precision/resolution of the timeextent has to be set as year.

The validation of the time parameter against the time extent with year 
precision gives some strange results. We were using the following getmap 
request for the tests:

parameter:  time=2022
result: returns all features of 2022

parameter:  time=2022-01-01/2022-12-31

It seems that if the precision of the time parameter is of -MM or 
-MM-TT the upper bound of the defined timextent 2005/2022 is not respected 
correctly.
We got the same result with the timextent defined  as: 2005/2022/P1Y

What isn't working with the configuration you have in place on docker? The 
locations aren't virtual hosts so they'd be sharing a mapserver config file. 
The config file support will fall back to an environment variable if the value 
isn't set explicitly in the config file - we get that for free with the CPL 
functions being used. So, at first glance it seems like having a custom value 
for MS_MAPFILE based on location should work assuming you don't have that value 
set in the mapserver config file.

Hi all,

I have a MapServer WMS that is returning GML query results, and all works well 
except that non-integer numeric fields are returning in scientific notation, 
eg.:

4.8601000e+02
1100
3.58893542070e+01
-1.20962789560e+02
7.500e-01

I see there is a metadata setting "gml_[item name]_precision" [1] that should 
allow specifying precision of these fields, but it seems it is not intended for 
GML output. Is this correct?

For example I tried setting this for the SIZE field:

'gml_SIZE_type' 'Real'
'gml_SIZE_precision' '2'

but this had no effect on the GML output:

7.500e-01

Is there another way that I can accomplish better output from this service? The 
source data format is a shapefile, and unlikely to change in this case.

thanks for any suggestions,

Based on that error message you're not running MapServer 8.0 though. That was 
an area that changed between v.7 and v.8 and the error message was updated. V.8 
outputs something like:

  msLoadMap(): Regular expression error. Filename validation failed.

Hi Marcin: Are you using FastCGI? Which version of MapServer? We ran into 
something similar w/FastCGI and version 8 during development where you'd see 
the first instance of an error message but then the server error subsequently. 
It was consistent on some setups but never happened on others. You could try 
applying the fix (see 
https://github.com/MapServer/MapServer/pull/6577<https://gcc02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2FMapServer%2FMapServer%2Fpull%2F6577=05%7C01%7Csteve.lime%40state.mn.us%7Ceabd7fa6ebbc4966680908dad47a7ab2%7Ceb14b04624c445198f26b89c2159828c%7C0%7C0%7C638055919758219015%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C=Af2O5Gg%2F4FPh%2BaokhLJZ1pWR9sGgpxBWR3bvzlRacYk%3D=0>)

Hello,



I am using Mapserver on Kubernetes (LoadBalancer). Everything works great -  
GetMap, GetCapabilities, layers load correctly in QGIS and Leaflet.

However, what caught my attention is that when passing the mapfile's url using 
LoadBalancer/Kubernetes IP, only the first time the message is



msLoadMap(): Regular expression error. MS_DEFAULT_MAPFILE_PATTERN validation 
failed



and every time thereafter



Internal Server Error

The server encountered an internal error or misconfiguration and was unable to 
complete your request.



By refreshing a few times, you may get the expected message again, but this is 
random. As I mentioned - layers and requests load correctly everywhere (also 
after repeated refreshing). Should I be concerned? I would love to understand 
why is this happening ^^

Not explicitly. There might be a was to simulate something, perhaps doing

I checked the documentation and found nothing related. So currently MapServer

Re: [MapServer-users] mapserver 8 - CGI map_object substitutions broken?

[Lime, Steve D (MNIT) via MapServer-users]

Easy solution - cool. You can do that with straight runsubs and relatively easy 
validation. Here's a nice document on the topic 
https://www.regextutorial.org/regex-for-numbers-and-ranges.php. I updated an 
existing ticket to clean that documentation up and remove some other cruft 
towards the bottom of that documentation.

emails to Minnesota IT Services Security Operations Center.


Well that's... not shocking.  I'm imagining the regex that might sanitize a URL 
with all that syntax in it... ughh...   *crumplecrumplecrumple* ~toss~

As for my own work... I realized yesterday late that I was going to have to 
find an alternative anyway.  All these maps need to go into Mapcache.  Turning 
that map_object notation into an intuitive mapcache dimension is a big ol Nope. 
 I can likely pass in a parameter on the URL (=10)  and then use 
multiple classes in the vein of  CLASS: EXPRESSION (%fontsize% = 10).  Voila.  
Easy mapcache dimension, easy sanitizing, supports a reasonable number of font 
sizes.

So I guess the item for the maintainers to fix is actually the documentation ( 
https://mapserver.org/cgi/controls.html
 )  which still makes it look like you can use map_object notation on the URL 
in MS8.

Thanks for the info!

Hi Tim: I was wondering if I'd see any messages on that topic. Short story is 
that the functionality was removed in MS8. I never liked the all-or-nothing 
aspect of it and was working on a method to control which objects would be 
allowed to be updated. The solutions I came up with were convoluted and were 
going to add a lot of complexity to the codebase for little value. That 
functionality is poorly documented and by itself overly complicates the code. 
So after a note to mapserver-users trying to judge how much it was used - with 
limited replies - it was decided to remove it. I'm dealing with my own upgrade 
issues as a result, but it's worth it in the end IMHO.

If necessary, it's better to revisit with another method - ideally something 
along the lines of runsubs. The challenge is specifying when to apply them and 
how to validate values. Strings are easy, but numeric/color values aren't so 
we'd need to do something like add runtime bindings (similar to attribute 
bindings) so you'd write SIZE %mysize% instead. One advantage being you could 
reuse the variable across layers.

So, what are the options right now? It sort of depends on your needs. Do you 
need to only support a couple of sizes for a class or do you truly need *any* 
size? Options include:

  *   multiple mapfiles - probably using includes to limit redundancy
  *   class groups
  *   if you're using a db backend I think attribute bindings could work paired 
with runsubs
DATA "shape FROM (select *, %textsize% AS textsize FROM ...)
VALIDATION
"textsize_default" "13"
"textsize" "^8|10|12|14$"
END
CLASS
  LABEL
SIZE [textsize] # I think attribute binding works here
  END
END

  *   MapScript - load the mapfile, do the changes you need, render the map
Happy to discuss further and perhaps other folks have ideas.

Good afternoon, all.

Hi all: This is in regard to 
https://mapserver.org/cgi/controls.html#changing-map-file-parameters-via-a-form-or-a-url
 – we’re seriously thinking about dropping this functionality as part of 8.0. 
It’s just not as relevant as in the past with improvements runtime 
substitutions and SLD. This will allow us to simplify the code related to 
mapfile processing a good bit and just make things easier to maintain in the 
long run. I am curious if and how folks are using this feature – just to 
identify high-value use cases that we might need to address.

Is it possible currently to use truetype symbols as polygon fill symbols?

The symbol creation page suggests that only hatch and pixmap symbols are used 
for polygon fills but that seems a bit weird to me and am wondering if that is 
just out of date?

If not, where is the best place to make a feature request?

Re: [mapserver-users] How to dynamically change MapServer's GRID MININTERVAL?

[Lime, Steve D (MNIT)]

Hi David: That functionality was geared towards common use cases so I’d bet 
money it’s not supported but I’ll check the code to be sure. If you’re really 
just after 5 vs. 10 then using multiple layers would be an easy work around 
(e.g. grid5 vs grid10). Note that we’re always interested in 500 errors so if 
you are able to pass along how you triggered one that would be helpful. --Steve

Subject: [mapserver-users] How to dynamically change MapServer's GRID 
MININTERVAL?

I started looking into using something similar to this example of the GRID 
layer definition in a MapServer mapfile that will draw lat/lon line grid at 
least every 5 degrees:

LAYER

  NAME "grid"

  METADATA

"DESCRIPTION" "Grid"

  END

  TYPE LINE

  STATUS ON

  CLASS

NAME "Graticule"

COLOR 0 0 0

LABEL

  COLOR  255 0 0

  FONT "sans"

  TYPE truetype

  SIZE 8

  POSITION AUTO

  PARTIALS FALSE

  BUFFER 2

  OUTLINECOLOR 255 255 255

END

  END

  PROJECTION

"init=epsg:4326"

  END

  GRID

LABELFORMAT '%g°'

MININTERVAL 5

  END

END # Layer

However, I don't want the MININTERVAL value to be hardcoded and would like to 
be able to vary that value by entering a different value in the URL call from a 
web page using the map_object notation. But, I've been unsuccessful. I have 
tried this in the URL call to MapServer:

_layer[grid].grid[0]=MININTERVAL+10 #changing to 10 degrees instead of 5

using the second example at this link: 
https://mapserver.org/cgi/controls.html#cgi-mapfile-change-parameters.
 But, I either get a parsing error or an Internal Server error. I've tried 
turning debug level to 5 and looking at logs but they don't offer any help. 
Perhaps I'm just not using the correct map_object notation, but I'm not sure 
what else to use given the examples in the link. I also attempted to look at 
the MapServer code to no avail.

Perhaps I just can't change this parameter via the URL?

I'm using MapServer v 7.2.2 but it seems like the GRID layer has been available 
for a while now.

Thanks for any help/suggestions/thoughts!

Re: [mapserver-users] PIXMAP Symbols png and jpeg not recongnized

The warnings look legit. I did a quick search and neither of those global 
variables are being used anywhere in the source (PNGsig is actually defined 
twice in 7.4, once in mapsymbol.c and again in mapogcsld.c). I assume that 
means they can be removed and/or the warnings can safely be ignored. Perhaps 
your compiler is just newer and therefore smarter?

Re: [mapserver-users] wms servers html template output

[Lime, Steve D (MNIT)]

Hi Travis: I don’t think there is an “easy” way. I mean you could script 
template creation so that process does the tedious work for you by looking at 
the map. You would create a new-style template (see RFC 36) so everything is in 
one file and then you’d create a single output format reference to that table.

If we wanted to support this via MapServer templates I think we’d need to do 3 
things:


· Extend the [resultset] tag to support “layer_pattern” attribute so 
that it (a regex) could apply to multiple layers (like any/all of them).

· Enhance the [items] and [values] tags to control formatting. 
Currently those just slam the column names and values together in a delimited 
string.

· Enhance the [values] tag processing to allow referencing the 
associated item/column name in the context of formatting.

I’d probably also propose compliance with the item-related metadata that is 
typically used with OGC service outputs to control which items are output…

With those changes you could write a template like so:

// MapServer Template
[resultset layer_pattern="."]
[feature]

[values format=”$item$value]

[/feature]
[resultset]

This would give you an item/value table for any feature for any layer. You 
could also to more horizontal tables using the [items] tag to output one header 
row…

Hello,

I am still having issues restricting the extent in my mapcache area using 
rulesets.  I created a rule for all of my zoom levels that has a limited 
visibility extent.  However, Mapcache is still returning imagery for the entire 
grid area even though I created a rule that should only display a limited 
extent.  I am still not sure why the visibility extent rule seems ineffective.

Thanks!


You can set the

empty_img

To return a blank tile.  I believe the status is still 404 - I don't think you 
can control this

mapcache returned 404 errors for any tiles outside of the restricted extent.  
Next I tried to use rulesets instead.  The rulesets seem to have no effect, and

 Question 1:  When we use restricted extents on a grid should MapCache return a

 Question 2:  Do I have my ruleset configured appropriately?

Re: [mapserver-users] Mapserver no longer reading pgpass file?

[Lime, Steve D (MNIT)]

I've never used that mechanism.


MapServer doesn't read or otherwise utilize that file or environment variable 
itself so the functionality must be inherent to the underlying Postgres C 
client library.


What packages did you update? Perhaps there was a permission change, missing 
Apache module (to set environment variables) or something along those lines?

Hi List,

My MapServer mapfiles have been set up to read a Postgres connection with

`PG:host=... post=... dbname=...` etc for some time now.

I upgraded the packages on my linux box and the mapfiles no longer work (error 
when connecting to postgres). However, running gdalinfo "PG:host... ..." using 
the exact same connection string works fine.

I realized that it's an authentication issue as the mapfiles work fine again 
when I add password=... to the connection string.

I have a pgpass file in the cgi-bin, and one in my home directory which is 
referenced with the PGPASS environment variable. Why would mapserver suddenly 
not provide the correct password or consume the pgpass file anymore? Does it 
need to be somewhere else? Why does it work fine with gdalinfo without the 
password?

Thanks,

2.   Edit the mapfile and add “ows_denied_ip_list” “my IP” to the WEB

3.   Perform the same WMS request in the browser – result was a WMS

4.   Edit the mapfile and change the ip slightly so it shouldn’t match but

5.   Perform the same WMS request in the browser – result was a PNG image.

I did tried multiple IPs in the list, with and without my IP and everything

I didn’t try a GetFeature… request.

  "ows_denied_ip_list" "xxx.xxx.xxx.xxx yyy.yyy.yyy.yyy zzz.zzz.zzz.zzz"
or using a file where there is the same list one IP for line

 "ows_denied_ip_list" "file:/path-to-file/file-with-ip-list.txt"

The values listed are the possibly values of our proxy.
So I guess setting them as denied IP mapserver should refuse to give a map to 
every client wms using them.
Instead the map are still showed.

I'm using QGIS as wms client to test it.

Re: [mapserver-users] ows_denied_ip_list is working ?

[Lime, Steve D (MNIT)]

The original RFC that proposed the feature addition does reference using CIDR 
notation for ips. I’ve not tested that specifically though…

Hi Steve,

thx for your test.
I do more test to try to understand better what I'm wrong.

Just to do a better with an more large IP range.
Is possibile to use the IP/CIDR sintax to describe the IP range or need to list 
all the IP denied ?

Thx,

Re: [mapserver-users] labels for pie|bar charts

MapServer now supports multiple labels per feature so perhaps it’s a reasonable

Thanks Steve!
Yes, correct. Labeling slices was not possible back then as well.
The annotation layer was kind of a workaround.

Will give it a try with your code snippet.

Re: [mapserver-users] labels for pie|bar charts

[Lime, Steve D (MNIT)]

You weren't labeling slices with PHP from the looks of it, just the underlying 
feature using an annotation layer. So setting up a layer to behave like an 
annotation layer is doable... Here's a simple snippet for the state of 
Minnesota polygon:

  LAYER
NAME bdry_statepy2
STATUS DEFAULT
TYPE POLYGON
DATA ' bdry_statepy2'
CLASS
  LABEL
TEXT 'Minnesota'
POSITION CC
SIZE LARGE
COLOR 0 0 0
  END
END
  END

Basically using a class with no styles.

I don't recall the individual chart components (pies, bars, etc...) as being 
labelable. It's not covered in the docs or the original RFC. I will whip up a 
test case to confirm the behavior though.

Hello Steve,

you are right. With older versions of Mapserver I used 2 layers.
One for the chart (type=chart) and the other one to do the labeling
(type=annotation).
I used PHP Mapscript at that time. See the code snippet for the
annotation layer below. It uses the same data source like the chartlayer.

$layer = ms_newLayerObj($Map);
$layer -> set('status', MS_ON);
$layer -> set('labelcache', MS_ON);
$layer -> set('type', MS_LAYER_ANNOTATION );
$layer -> set('data', $datapath);
$layer -> set('status', MS_ON);
$poClass = ms_newClassObj($layer);
$poClass-> set("name", "Beschrifung " );
$felder= '(';
foreach( $chartLayer['fieldlist'] as $feld ){
   $felder .= sprintf('%s = [%s]-', $feld, $feld);
}
$felder .=sprintf(')');
$poClass->settext($layer, "$felder");
$poClass-> label -> set('font', "arial");
$poClass-> label -> set('type', MS_TRUETYPE);
$poClass-> label -> set('size', 8);
$poClass-> label -> set('antialias', MS_TRUE);
$poClass-> label -> color -> setRGB ( 0, 0, 0 );
$poClass-> label -> set ('wrap', 0x2d); // use '-' to do a line break
$poClass-> label ->set('position', MS_AUTO);
$poClass-> label ->set('partials', MS_FALSE);
$poClass-> label ->backgroundcolor->setRGB('240','240','240');

Unfortunately this approach do not work anymore as the annotation type
is not longer supported.

The MapFile which I am trying currently looks like this:

  LAYER
DATA
"/home/nicol/public_html/geoworld/gw2_1und1/data/brd/media.shp"
LABELITEM "NAME"
NAME "Staedtecharts"
PROJECTION
  "init=epsg:4326"
END # PROJECTION
STATUS DEFAULT
TYPE CHART
# PROCESSING "CHART_SIZE_RANGE=bevzahl"
# PROCESSING "CHART_SIZE=130" # Fixe Groesse
PROCESSING "CHART_TYPE=pie"  # pie, bar
PROCESSING "CHART_SIZE_RANGE = itemname minsize maxsize minval
maxval exponent"
PROCESSING "CHART_SIZE_RANGE=bevzahl 30 300 10 200"
LABELITEM "NAME"
UNITS DD
CLASS
  NAME "Maennlich"
  TEXT 'Hallo'
  LABEL
FONT "arial"
SIZE 30
COLOR 255 0 0
ENCODING "UTF-8"
MINFEATURESIZE AUTO
OFFSET 0 0
POSITION AUTO
SHADOWSIZE 1 1
  END # LABEL
  STYLE
COLOR 192 192 192
OUTLINECOLOR 0 0 0
SIZE [mann]
  END # STYLE
END # CLASS
CLASS
  NAME "Weiblich"
  STYLE
SIZE [frau]
COLOR 255 255 0
    OUTLINECOLOR 0 0 0
  END
END
  END # LAYER


My hope was that the chart type now also takes care of the labeling.

Any idea how to realize the labeling for the individual slices now?

Thanks
Nicol

Hello,

I am trying to understand how labeling/annotation with layer type
'chart' for the individual slices e.g. of a PIE/BAR chart would work (
https://gcc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fmapserver.org%2Foutput%2Fdynamic_charting.htmldata=02%7C01%7Csteve.lime%40state.mn.us%7C6232218953ac431b0e4c08d715f1180f%7Ceb14b04624c445198f26b89c2159828c%7C0%7C0%7C637001997557352724sdata=ZFkZ8QsEuUaAGFyFIxfZjWK9XR8QeyDBv390t2p%2F23o%3Dreserved=0).
I have tried to set a LABELITEM on layer level, a LABEL block within
the CLASS section, a TEXT property in the CLASS block but none of my
attempts show any labels.
In earlier versions of Mapserver I have used the ANNOTATION layer type
to get labels but this type is now deprecated for 7.x versions.
Any ideas?
Thank you very much.

every client wms using them.
Instead the map are still showed.

I'm using QGIS as wms client to test it.

Hi,
I see my version of mapserver don't work the ows_denied_ip_list.
I see ths other mex:

I try all the same option but nothing is work.

So I guess that instead that the ows_denied_ip_list was dismissed.
Is this confirmed ?

Re: [mapserver-users] Is there a way of getting existing settings from a mapfile via CGI?

[Lime, Steve D (MNIT)]

By mapfile settings do you mean a list of mutable properties by layer, class, 
style, etc...? If so, then no, that doesn't exist as part of the CGI. I would 
think doing so would be pretty challenging in a generic way.

All,

I have a thought on populating a FORM with the results of a “MapFile SETTINGS” 
query.  The end game being a  method for users to change current settings on 
the fly.

Could I need to build a generic template for this, or would all exceptions need 
to be handled, like missing values, etc?  What happens if something doesn’t 
exist as a setting in the return . .

Just thinking out loud.

Using mostly WMS/WFS calls to MapServer right now, so I could possibly go the 
SLD route, but, other thoughts?

Hello all.


We have set up MapServer using MS4W, running against IIS.  We have a .map file 
defined to include about a dozen layers contained in an ESRI GDB format.



All of this works fine for the initial load of the map, but following any data 
changes, we would like to be able to force a refresh of the map without having 
to reload the entire page.  For example, if we simply drag/pan the map, the 
layers will refresh with the latest data using the current zoom-level/extents; 
but we would like to programmatically refresh the view when data has changed.


Up to this point we have exhausted what we feel are the relevant OpenLayers API 
calls found at 
http://dev.openlayers.org/docs/files/OpenLayers-js.html<https://gcc01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fdev.openlayers.org%2Fdocs%2Ffiles%2FOpenLayers-js.html=02%7C01%7Csteve.lime%40state.mn.us%7C2eec587306d04dfb3ffc08d70ae264ad%7Ceb14b04624c445198f26b89c2159828c%7C0%7C0%7C636989839771390369=UWweeLR2vqMT3mghppc%2F08GUeYY97a11XN0MQu2lZd8%3D=0>
 (OpenLayers.Layer, OpenLayers.MapServer, & OpenLayers.Map). Everything that 
we’ve tried so far seems to simply reload the last cached image.



Another developer working with this has set up buttons that recenter the map to 
predetermined locations. This is what he has reported.

  *   Whenever we press one of these, we create a new OpenLayers.Map object 
(always with the same extents) and OpenLayers.Layer.MapServer (always with the 
same params). Then, we add the layer to the map object and call setCenter, with 
the lat-long and scale.
  *   If we center on Location A, then move a map marker (via a separate 
application) and go to Location B, the marker is seen in its new position. But 
if we click the button to recenter back on Location A, the marker appears to 
return to its old position. We suspect this is because the browser or the 
server is reusing a previously generated map image. If we reload the entire 
page, the marker is shown at its correct position.


Thank you for any insight/feedback you could provide.

Kind Regards.

Hello Steve,

thanks for answering. I have changed the extent definition in grid

Any ideas will be appreciated.

Re: [mapserver-users] Adding cache control headers to wms requests

[Lime, Steve D (MNIT)]

I guess the question is whether this belongs in MapServer or if it should be 
done at the web server level - you shouldn't need to write a wrapper process. 
The mod_headers module provides this for Apache and since you can use the 
module in any container (e.g. ) you could set headers based on things 
like the value of the map parameter or the WMS request type. I would guess 
other web servers provide similar functionality but I don't know that for sure. 
That seems extremely flexible IMHO.

Currently the setting max-age is supported in 3 spots within MapServer: 
WMS/GetMap (1), mode=map (2) and mode=legendicon (3) CGI requests. Other 
request responses don't look for or set it and probably should in a more 
general solution.

Subject: [mapserver-users] Adding cache control headers to wms requests

Hi all,

I need to add the following headers to some wms responses:

|Cache-Control: no-cache, no-store, must-revalidate Pragma: no-cache
Expires: 0 I am aware that I can set: MAP WEB METADATA ...
"ows_http_max_age" "0" END END ... END But it seems like it would be a
good idea to be able to set additional headers also. Maybe something
like: WEB HEADERS "||Cache-Control: no-cache, no-store, must-revalidate|"
 "|Pragma: no-cache|"
 "Expires: 0"
   END
   METADATA
 ...
   END
END

This would provide an easy way to add arbitrary response header.
The various headers are because browsers are not consistent which headers they 
respond to.
See||   
https://stackoverflow.com/questions/49547/how-do-we-control-web-page-caching-across-all-browsers

||
Maybe we can already do this and I'm not aware of how. I could write a wrapper 
around mapserver and
funnel some requests through it to do this, but it would be nice if mapserver 
via the mapfile can do it.

Thoughts?

Re: [mapserver-users] Recommendations for SVG Sizing in MAPSERVER?

[Lime, Steve D (MNIT)]

I don't believe you can muck with the SVG color since SVG can carry multiple 
elements and colors. That complexity doesn't map very well to a single color 
value in a styleObj. It's probably best to consider SVG as immutable, same as 
an image symbol. You can use truetype fonts (or vector symbols) if you want 
something scaleable where you can alter color.

Hi Steve,

Thanks for the tip. I used the link you provided and was able to get the SVG 
symbol sizing to a reasonable level. I appreciate the help.

I did have another question, maybe you know this. In the most recent version 
MAPSERVER, are we able to change the color of SVGs using the COLOR parameter? 
It does not seem that we are able to do so. I found a couple topics on the 
forum but they were from a few years ago. I am not sure if anything has changed 
or if I am missing something.  Maybe you know the answer to this as well? 
Thanks for your help!

Subject: [mapserver-users] Recommendations for SVG Sizing in MAPSERVER?

Hello,

I am fairly new with MapServer and was wondering if anyone had any 
recommendations or guidelines of sizing point symbol SVG's?

I created some SVG symbols in Inkscape. When I load them into MapServer and 
choose SIZEUNITS feet, I have to set the actual symbol size to around 500 for 
these to show up in a Map. My understanding is that the SIZEUNIT parameter 
changes the way the symbol rendered in real world space (in my case feet rather 
than pixels). I am not sure if this has to do with how the SVG is sized in 
Inkscape or if there is an issue with using SIZEUNITS and SVGs together in 
MapServer. I looked at the MAPSERVER documentation online and did not have much 
luck.

I have tried a few things including setting the MIN and MAX Size with no luck. 
Any help or pointers would be awesome.

Thanks for your help!

Re: [mapserver-users] Recommendations for SVG Sizing in MAPSERVER?

[Lime, Steve D (MNIT)]

Hi Brian: Welcome! My guess that the SVG file might be "sized" to whatever page 
size you had defined in Inkscape and your elements may be significantly smaller 
than that. Basically I'm wondering if there's a bunch of empty space that is 
also being scaled and your actual symbol would appear proportionately smaller 
as well. If this is the case it looks like you can do things in Inkscape to 
remove that space...

Subject: [mapserver-users] Recommendations for SVG Sizing in MAPSERVER?

Hello,

I am fairly new with MapServer and was wondering if anyone had any 
recommendations or guidelines of sizing point symbol SVG's?

I created some SVG symbols in Inkscape. When I load them into MapServer and 
choose SIZEUNITS feet, I have to set the actual symbol size to around 500 for 
these to show up in a Map. My understanding is that the SIZEUNIT parameter 
changes the way the symbol rendered in real world space (in my case feet rather 
than pixels). I am not sure if this has to do with how the SVG is sized in 
Inkscape or if there is an issue with using SIZEUNITS and SVGs together in 
MapServer. I looked at the MAPSERVER documentation online and did not have much 
luck.

I have tried a few things including setting the MIN and MAX Size with no luck. 
Any help or pointers would be awesome.

Thanks for your help!

Sincerely,

Re: [mapserver-users] Stretching subset of a raster

[Lime, Steve D (MNIT)]

Hi Asen: Hmmm… What version of MapServer and GDAL? The scaling should be 
happening in GDAL before the data hit MapServer so the [pixel] values MapServer 
gets are already between 0-255 in both of your cases. What I don’t know is what 
GDAL does with values outside the scaling range – so with SCALE=10,20 what do 5 
or 50 get mapped to.

Do you have a sample GeoTiff to play with?

Since i'm a newbie on this subject, perhaps something needs to be configured

You can use MapCache without MapServer. You’ll need something to provide WMS

Within Mapcache, Is it considered "good form" to modify the

closer to the map?  Will I just need to override the grid in mapcache.xml, or 
will I need to create a new grid by copying the parameters on

Background:
WMS seems to work in ArcMap using any MapCache grid (UTM 15N, Lyon County, 
Google, WGS84).  However when using WMTS, ArcMap only displays the Google and 
WGS 84 grids in the correct location.  Therefore I plan on using the 
GoogleMapsCompatible grid until the issue with ArcMap is resolved, but I would 
like to zoom in closer on the map.

Re: [mapserver-users] Mapcache WMTS - imagery is offset in ArcGIS when using WMTS services.

[Lime, Steve D (MNIT)]

The resolution doesn't matter. That just impacts scale computations internally 
so when layers/classes are on/off and how symbol/font scaling is done.

I just tried our Compass MapCache/WTMS service overlaid with a shapefile in UTM 
projected appropriately and they line up perfectly in ArcGIS 10.6. You can try 
it too with your data since you're in MN

I noticed that WMTS services are extremely fast when using Mapcache to serve

significantly from the actual location.   I did notice that Mapserver and 
Mapcache use a 72 DPI while ArcGIS is using a 90.714 DPI.  In addition the 
image is the correct width and height.  In addition, when I use WMS the imagery 
appears in the correct location, however it is not as fast as WMTS.

Please let me know if there is a way to get ArcGIS to place imagery in the

Should be easy enough to replicate. Does this sum it up?


· Label TEXT w/expression followed with a comment containing ()’s - 
FAILS

· Same TEXT w/expression but with moving the comment containing ()’s

· Label TEXT w/expression followed with a comment without ()’s – WORKS

Hi list,

I have observed an obscure behavior in MapServer version 7.0.7, which I’d like 
to run by you before I submit an issue.

I have an issue where labels on contour line disappear when I write a 
particular type of comment after the TEXT directive.

Using this request:

this piece of MAP file

   CLASS
 GROUP "default"
 NAME "dhm2015 kurver, 0,5 m"

 TEXT (tostring([hoejde],"%.2f")) #altid to decimal, også .00 (eng. always 
two decimals, including .00)
 STYLE

Gives me

 (contour lines w/o labels), whereas

   CLASS
 GROUP "default"

 #altid to decimal, også .00 (eng. always two decimals, including .00)
 TEXT (tostring([hoejde],"%.2f"))

COLOR 137 90 68
OFFSET 0 -6
SHADOWSIZE 1 1
TYPE TRUETYPE
REPEATDISTANCE 300
ANGLE auto
PARTIALS FALSE
  END # LABEL
   END #CLASS

Results in https://pasteboard.co/I6js9YK.png (which is the desired result: 
Contour lines labelled with two decimal points).
I have narrowed it down a bit, and if I delete the “(eng. ..)”, i.e. just have
 TEXT (tostring([hoejde],"%.2f")) #altid to decimal, også .00
It still works nicely.

So I guess the parentheses are somehow parsed as something meaningful (related 
to the “tostring”-expression, perhaps?), invalidating the TEXT declaration.

Has anyone seen something similar?

Hello all!

Today is a big day as Gateway Geomatics is truly proud to announce that 
MS4W 4.0.0 is finally available! This is a huge release of changes, as 
every library (over 200 now) has been upgraded and built with a new 
compiler (Visual Studio 2017), and contains many great additions 
overall.  Get it now at 
https://gcc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fms4w.comdata=02%7C01%7Csteve.lime%40state.mn.us%7C6da74ed8fc194b404fee08d6a73d0019%7Ceb14b04624c445198f26b89c2159828c%7C0%7C1%7C63688020977424sdata=9Qdku2702wLP3Z6M6Y8x2o7pI2cHVkcbR5pgNLjEESg%3Dreserved=0

Please see MS4W's HISTORY.txt for all of the changes (or the bottom of 
this email for the full list), but here are some of the highlights:

  - PHP7 mapscript support (using the SWIG API)
  - PHP 7.2.16
  - embedded Python 3.7.0
  - running pycsw Catalogue Server
  - expanded ZOO-Project WPS support (all GDAL/OGR services, Python, 
PHP, CSharp, Java)
  - new Matomo Analytics package
  - simple map viewer on the localhost page
  - GDAL 2.4.0
  - MapServer 7.4.0-dev
  - mod_wsgi for Apache
  - Mapbox Vector Tile output through MapServer (demo included)
  - osm2pgsql commandline utility
  - many HTTPS config changes and fixes (including a workaround for a 
show-stopping MapCache issue on some systems)
  - enhancements to the setup.exe installer
  - and many more...

You can see that MS4W-4.0.0 is a full SDI for Windows environments, with 
~40+ working mapfiles and over 1.7GB of files, empowering DevOps and 
organizations worldwide.  Also note that this is a major release for 
MS4W, meaning that some things have changed dramatically (PHPmapscript 
will now use the SWIG API for example), so please follow MS4W's README 
for specific instructions for the many plugins and mapscripts.

When installing, it is very important that (if you are using the .zip) 
your server must have the C++ Redistributable installed on it 
beforehand: execute the local file /ms4w/tmp/vcredist_x86.exe 
(alternatively if you use MS4W's setup.exe installer this is done 
automatically)

As always please provide your requests for enhancements and issues 
through the MS4W tracker (so the feedback is not lost or forgotten):

Re: [mapserver-users] MapServer derived MVTiles Benchmark test vs. T-Rex tile server

[Lime, Steve D (MNIT)]

Will have a look... I hadn’t spent much time on optimization at this point. I 
wouldn’t doubt there might be improvements to be made. The simplification code 
would be the spot to look.

Extent represents the resolution of the tile and guides the simplification done 
as part of the conversion from world to mvt coordinates. Edge buffer defines 
tile overlap.

By chance have you done output comparisons at all? That is, tile to tile in 
terms of size: feature counts, point counts/feature, etc... That would help 
tune the format parameters and make sure MapServer is returning reasonable 
output.

One quick note on the SQL (2) is to be explicit with returned columns, avoid *. 
The t-rex SQL hints at zoom-related attributes in the layer? Again, will have 
to find time to checkout the benchmark stuff.

Subject: MapServer derived MVTiles Benchmark test vs. T-Rex tile server

Dear All,

I  am working on optimizing a MapServer /MapCache configuration of  a benchmark 
for creating MVT tiles (seeding) of MapServer - versus T-Rex.

This will be featured in a presentation at the German FOSS4g ('FOSSGIS') 2019 
in Dresden at the end of this week. The whole thing is based on Pirmin 
Kalberer's automated vector tile benchmark see - 
http://blog.sourcepole.ch/2018/09/06/the-tale-of-a-vector-tile-benchmark/<https://gcc01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fblog.sourcepole.ch%2F2018%2F09%2F06%2Fthe-tale-of-a-vector-tile-benchmark%2F=02%7C01%7Csteve.lime%40state.mn.us%7Ca811ae33be2d46f58eed08d6a67469eb%7Ceb14b04624c445198f26b89c2159828c%7C0%7C0%7C636879416281241691=Rq7vxQk62vpPNJ4qjeq4fkLSuvSJ46t3Bicj760mTCU%3D=0>
 . Thus I created a similar configuration of the Natural Earth Data based world 
map for MapServer (my favorite rendering engine !) to run it against T-REX.. 
Now Pirmin has added this into the GitHUB repository as a 'MapServer' branch 
see - 
https://github.com/pka/mvt-benchmark/tree/mapserver<https://gcc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fpka%2Fmvt-benchmark%2Ftree%2Fmapserver=02%7C01%7Csteve.lime%40state.mn.us%7Ca811ae33be2d46f58eed08d6a67469eb%7Ceb14b04624c445198f26b89c2159828c%7C0%7C0%7C636879416281251699=0j4MMJBWx5IYNszsZPrSY1RRTGzvicRUoPw1BZGGcqk%3D=0>

Results of one of my first trial benchmarks can be found here 
https://github.com/karstenv/mvt-benchmark/tree/master/firsttests<https://gcc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fkarstenv%2Fmvt-benchmark%2Ftree%2Fmaster%2Ffirsttests=02%7C01%7Csteve.lime%40state.mn.us%7Ca811ae33be2d46f58eed08d6a67469eb%7Ceb14b04624c445198f26b89c2159828c%7C0%7C0%7C636879416281261701=cu3VQvVDV2ieGjZs6Lld9kLa7SK0W%2FJe27Ak%2BJqcZSc%3D=0>
 .

Unfortunately my favorite software (MapServer /MapCache.fcgi) is falling pretty 
far behind in seeding speed in these tests
see e.g. in 
https://github.com/karstenv/mvt-benchmark/blob/master/firsttests/http.jpg<https://gcc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fkarstenv%2Fmvt-benchmark%2Fblob%2Fmaster%2Ffirsttests%2Fhttp.jpg=02%7C01%7Csteve.lime%40state.mn.us%7Ca811ae33be2d46f58eed08d6a67469eb%7Ceb14b04624c445198f26b89c2159828c%7C0%7C0%7C636879416281271709=K7o4vKUwAbL79z%2BPMElpMwMkPXtRNr%2BQO708LgTJN%2Fg%3D=0>

Thus, I wanted to call in the experts to find out what configuration tweaks 
will help to increase the MapServer / Mapcache  performance.

So far my next steps I will be working on
--
1.) Setting the correct map file parameters to match the T-Rex configuration 
for the FORMATOPTIONS
"EXTENT" and "EDGE_BUFFER" in the OUTPUTFORMAT  bloc.

OUTPUTFORMAT
 NAME "mvt"
 DRIVER MVT
 FORMATOPTION "EXTENT=512" # default is 4096. # Comment by Pirmin for t-rex 
this is 'tile_size' (per Layer): Width and height of the tile (Default: 4096.

Re: [mapserver-users] Arc symbol.

[Lime, Steve D (MNIT)]

Not within MapServer directly, at least not at first glance. There are circle 
layers but there’s no way to limit drawing to just a specific arc on that 
circle. Here are some other ideas:


1)  Perhaps it could be done externally in OGR or PostGIS and then rendered 
in MapServer as a polygon or a line…

2)  You could also take a look at using javascript geotransformations: 
https://mapserver.org/mapfile/geomtransform.html#javascript-transformation 
Support was added a while back and isn’t widely used but this is the sort of 
thing it was added for. In theory you should be able to compute the arc 
yourself and return it for rendering. So you pass in the 2 lines and then 
return the arc as a line shape or a pie slice as a polygon shape. (maybe this 
helps… 
https://stackoverflow.com/questions/45009327/draw-arc-between-two-lines-i-need-to-calculate-points)

If option 2 works this would be a great thing to archive – a library of 
geomtranforms. I might tinker with this tonight… ;-)

Subject: [mapserver-users] Rendering TrueType labels.

Hello All,

Can anyone explain how the rendering engine works? For example I have 
four layers:

case1. Polygon

case2. Point which is presented as symbol (circle) with truetype label

case3. Polygon which is more detailed version of layers case1

case4. Point which is presented as symbol (circle) with truetype label 
which is more detailed version of layers case2

The problem is that composition (shadownig) during rendering (default 
src-over compop) works only for Polygon and Symbol. The label is 
preserved and final tile has one Symbol but with two labels. Is there 
any way to disable that behaviour?

Re: [mapserver-users] probleme mapserver 5.x tutorial

Hi: In that particular example the states label layer should become:

  LAYER # States label layer begins here
NAME states
DATA states_ugl
STATUS   OFF
TYPE POLYGON

PROJECTION
  "init=epsg:4326"
END

CLASSITEM"CLASS"
LABELITEM"STATE"

TYPE TRUETYPE
FONT arial-bold
SIZE 12
ANTIALIAS TRUE
POSITION CL
PARTIALS FALSE
MINDISTANCE 200
BUFFER 4
  END # end of label
END # end of class
  END # States label layer ends here

The reason you might want to use a label style is for something like drawing a 
road shield paired with a road number but that’s not necessary in this 
particular case. We really do need to update the demo and tutorials for 7.0 and 
newer versions. The changes are minor but can be frustrating for a new user. 
Please feel free to reach out as often as you need and I’ll do my best to help!

Re: [mapserver-users] [mapserver-dev] Setup for MVT (was: Time for a 7.2.2 release?)

[Lime, Steve D (MNIT)]

BTW my MVT demo does have a sample mapache config included now. Note that the 
MVT creation does do simplification so for example you'll see islands in lakes 
disappear as they become degenerate and points removed from lines, etc 
That's the fun part and hat you need for scanline conversion is a little 
different from what Open/Web GL needs.

Hi Steve,

Thanks!, I put this back on the list so other can benefit from your 
thoughts.

Tiles at various scales is not intuitive to me either. If you don't 
simplify the geometries, then all you are getting it more features in 
each tile as you zoom out. But your point about degenerate geometries 
play right into this and you can't really simplify them except via 
clustering which makes more sense on the client side.

I was thinking of using this for serving point features to an OL5 
application. Since my case was so simple, I ended up writing a trivial 
PHP handler to do this using a bbox strategy, but I want to revisit that 
using mapcache and MVT because I think it would be good to learn and I 
think it would be more efficient on both the client and server, not that 
I need to worry that much about that.

Re: [mapserver-users] styling based on attribute for MapServer derived MVTiles

[Lime, Steve D (MNIT)]

You can specify a type in the gml metadata and that will impact how the 
conversion is done in the mvt encoding. Something like:

   gml_mapcolor7_type integer

Otherwise things are treated as strings...

Great, Thanks Steve
I added  "gml_include_items" "mapcolor7"
to the Metadata block and got it working.
One quirk seems to be that when I am trying to the values as integer (from the 
mapcolor7 column) specifying the style as in 1.) below did not work.
However it I treat them as characters instead, quoted them and used "type": 
"categorical" in the json file for the style as in 2.) below it is working.

I believe the default WxS behavior is to expose no attributes. You need to be 
explicit and I don’t see the gml_include_items metadata property in the mapfile 
for the layer allcountries. You’d need something like:



“gml_include_items”“mapcolor7”



Added to the allcountries layer. The mvt-demo does this for most layers…

See https://mapserver.org/input/vector/wfs.html for the former and

It’s actually GDAL/OGR that provides GeoJson read support. So assuming you have

I didn't know about lealet, which seems interesting: I will probably give it a

not wrong, this implies to develop a new interface, where I would prefer to

Besides, do they allow to make queries like MapServer does? The way MapServer

Re: [mapserver-users] How do a GetFeaureInfo on vector layer but showing raster layer ?

[Lime, Steve D (MNIT)]

Unfortunately you probably have to use mod_rewrite. It is possible to use 
MapServer to use its standard template processing to forward the query for a 
layer to another URL  or to use hidden layers and templates but to do so you 
have to be able to set the info_format to be used for the GetInfoRequest and it 
doesn’t appear that’s possible from QGIS – it always sets 
info_format=text/plain. If that’s not the case let me know and I can provide 
details on the MapServer-only methods.

Subject: [mapserver-users] How do a GetFeaureInfo on vector layer but showing

Hi,
I would like to show with QGIS the attribute of a vector layer when I request 
for information in a raster layer. Raster layer is an image from wms service 
that also provides the vector layer.

I have tried to solve the problem defining a GROUP layer but QGIS doesn't 
recognize layers in a group as queryable although each of them is queryable. 
This topic is well described here: 
https://lists.osgeo.org/pipermail/mapserver-users/2012-July/072892.html

I have also test apache rewrite_rules following this link:
https://github.com/mapserver/mapserver/issues/3310

I have a very little knowledge of mapserver but I guess the solution is using 
rewrite rules. The most examples I have found are about clean url, but I am 
looking for redirection from one map file to another.

The idea is to get attribute information from vector layer when user request 
for information in a raster image loaded from wms service in QGIS.
Is this possible ? Any help would be appreciated.

Thank you in advance !

Re: [mapserver-users] load an svg or a png or a gif as a map symbol in a map file

[Lime, Steve D (MNIT)]

You can do something like:

CLASS
STYLE
  SYMBOL 'http://maps2.dnr.state.mn.us/compass/lib/markers/02.png'
  SIZE 41
END
END

Where the symbol can reference a local file or a URL.

Re: [mapserver-users] OGR GeoJSON Layers...

[Lime, Steve D (MNIT)]

It may be my GDAL version, it’s a tad older. I will try and update that. Might 
be worth thininking about supporting runtime subs in the OGR url to pass extent 
values easily - where MapServer does the substitution using computed values. 
Kinda like the bbox hack for PostGIS.

The following works for me with MapServer 7.0.6/GDAL 2.2.  Note it doesn't 
appear to pass the bbox filter to the ESRI service so this only works with 
small layers (otherwise it will timeout).  With newer GDAL versions 
'OGRGeoJSON' will likely need to become 'ESRIJSON'.

Re: [mapserver-users] MapServer/MapCache vector tile test with max/min scale denominator

[Lime, Steve D (MNIT)]

Hi Martin: Hmmm... I'm surprised it works one way and not the other. I can only 
guess that a scale denominator is not being computed in one case versus the 
other. I can confirm the necessary check is being done in the MVT code (via 
msLayerIsVisible()) but if the basic information that function needs is not 
available then that's the problem.

Subject: [mapserver-users] MapServer/MapCache vector tile test with max/min

I've tested MapServer and MapCache with vector tiles using this 
MapServer branch:

https://github.com/sdlime/mapserver/tree/vector-tiles

And this MapCache PR:

https://github.com/mapserver/mapcache/pull/166

And it works.

I've also tested the layer level "max/min scale denominator" setting in 
MapServer to filter out layers in the vector tiles for different zoom 
levels, which also works when using Mapserver directly with the classic 
cgi interface, but not when using MapCache.

The max/min scale denominator kicks in with something likes this:

http://127.0.0.1/cgi-bin/mapserv.fcgi?map=/my_mapfile.map=tile=gmap={x}+{y}+{z}=all=mvt

But when requesting tiles through MapCache the max/min scale denominator 
doesn't kicks in at any zoom levels.

I believe its because MapCache is requesting tiles through the WMS 
interface of MapServer and for some reason that behaves differently?

The definition in the MapCache file is





    mvt

application/vnd.mapbox-vector-tile









   

     http://localhost/cgi-bin/mapserv.fcgi?

   

   

     

   public

application/vnd.mapbox-vector-tile

Subject: [mapserver-users] About the granularity of DEBUG on tileindex layers

Hi,

I have always used just "DEBUG 5" for debugging raster layers but now I finally 
made a test with Mapserver 7.0.1 for seeing what is the real difference between 
the debugging levels. I was a bit surprised to see that there is not so much 
difference at all, and that the DEBUG 1 level gives information that is missing 
from the higher debugging levels but that would be useful sometimes.

Debug 1 prints these lines
[Fri Nov 16 12:05:50 2018].964589 msDrawRasterLayerLow(layer_name): entering.

[Fri Nov 16 12:05:50 2018].980700 msDrawRasterLayerGDAL(): red,green,blue,alpha 
bands = 1,2,3,0



All debug levels from level 2 print these lines:

[Fri Nov 16 12:09:05 2018].581597 msDrawRasterLayerLow(layer_name): entering.
[Fri Nov 16 12:09:05 2018].589989 AUTO = +proj=utm +zone=35 +ellps=GRS80

bands = 1,2,3,0
[Fri Nov 16 12:09:05 2018].720794 msDrawMap(): Layer 3 (layer_name), 0.139s


The only additional item that debug levels 2 and above give is the rendering 
time msDrawMap that is often useful.  But at the same time the filename and 
path items which are present at debug level 1 are missing.

I suggest to add debug items msDrawRasterLayerLow(): Filename and 
msDrawRasterLayerLow(): Path should be added alto to debug levels >=2.  For 
being even more useful the highest debug level could give also timings about 
reading the tileindex and perhaps separate timings about things like how long 
does it take to read the "src" window from each "Filename" and if overviews are 
used or not.

Thanks very much for your reply.  I actually worked #1 out - I had the 
wrong units set in the grid.

I'm only using the style in the .map file, and haven't set min and max 
scale at this point.  Linecolor and width are (I think) sufficient, 
since it's just drawing a grid.

I've tried various combinations of TRANSPARENT TRUE, IMAGECOLOR 
"#FF" and IMAGECOLOR #00" in the mapfile, and turning 
transparent on and off in the mapcache file, and I get either white or 
black backgrounds in the cached tiles.  The mapserver tiles look fine in 
all cases.

Cheers,
Bob

Not sure if others replied off-list or not. It's hard to advise on issue 1 
since the mapfile and layer definition you sent in the subsequent email was 
incomplete. Knowing what styles you're using and any min/max scale values would 
help.

For issue 2 this is what I do for transparent tiles - I think you can just do 
one or the other but it doesn't hurt to do both:

  - set "true" in the WMS source definition params 
section. 
  - set "TRANSPARENT TRUE" in the mapfile (at the map level). You might need to 
set an IMAGECOLOR too depending on what you're drawing.  

In this example:

1. The layer is basically a grid structure - so a bunch of black lines.

2. Although the mapserver WMS service generates a transparent layer,

I hope not, each service should be isolated from another.

To find different services from a single provider you should search some 
metadata catalogue, perhaps:

Hi List,

Is there a way to get all the endpoints (maps) that are available from a given 
server?

Or put another way, take this example where these two URL's both use different 
map files, and so have different layers (one is pointing to 
"wms_4km_modisa-bbp.map", the other to "wms_9km_seawifs-pp.map"):

http://gmis.jrc.ec.europa.eu/cgi-bin/mapserv?map=/srv/www/htdocs/wms/wms_4km_modisa-bbp.map=wms=getcapabilities

http://gmis.jrc.ec.europa.eu/cgi-bin/mapserv?map=/srv/www/htdocs/wms/wms_9km_seawifs-pp.map=wms=getcapabilities

If I only knew one of those URL's, would it be possible for me to figure out 
the other one, ideally via a GET request?

Thanks,
Jonathan

Check out our MAP files for the City of Amsterdam reference map at
https://github.com/Amsterdam/mapserver/blob/develop/kbk50.map for the 1:50K 
map. The GROUP "lijnen" is the one you are looking for: it renders all casing 
from streets to regional thoroughfares, followed by the fills for the same 
lines. We then render all railroads and then the highways come last: again, we 
render the casings for all lines and then we finish with the fills in its own 
layer. This dataset doesn't contain an attribute for z-ordering unfortunately.

For the 1:5K and larger, there is the 
https://github.com/Amsterdam/mapserver/blob/develop/bgt.map MAP file that does 
have an attribute for z-ordering that we use to create views per z-level, e.g. 
"bgt.wegdeel_vlak0" for z-level 0.

Results can at https://data.amsterdam.nl/. Hope these MAP files give you some 
ideas how to go about rendering transportation networks.

Best,

Edward

Most of the battle is identifying the over/under in the data. Have you got that 
figured out?  I'd think it would be a matter of sorting: under, neither under 
or over and then over. Probably with no line caps.

All,



I'm looking for general techniques in how to best manage rendering of 
over/under roadway and rail road bridges, etc.



My first thought was to use some sort of special overlay layer to handle this.  
But maybe a database appraoch might be better.  I also start to fall into the 
problem of having a lot of transporation related layers,   Streets and 
Railroads obviously, but the not the so obvious are Alleys, Sidewalks, Park 
Trails/Paths, Bike Routes, tunnels, etc.



How to make these all stack nicely.  I generally maintain these things all in 
thier own grouping right now as separate datasets.  They originate from 
separate authors and are maintained that way too.  Which is why I was thinking 
that a DB approach might be the best to make the Z-indexing work.



Thoughts?



Thanks

Subject: [mapserver-users] Curves in MapServer

Hi list,

Does anyone know if MapServer supports WKT curves for feature geometries?
I've tried a layer with the definition below but end up with the following 
error:

msGEOSShapeFromWKT(): GEOS library error. Error reading WKT geometry 
"CIRCULARSTRING(1 5, 6 2, 7 3)". 
msGEOSError(): GEOS library error. ÉíKZ 


LAYER
NAME "Curve"
STATUS ON
TYPE LINE
FEATURE
WKT "CIRCULARSTRING(1 5, 6 2, 7 3)"
END
CLASS
STYLE
COLOR 204 204 255
WIDTH 3
END
END
END

Curve geometries seem to be supported in GDAL (see 
https://trac.osgeo.org/gdal/wiki/rfc49_curve_geometries) but not in GEOS (I'm 
using geos-3.4).

Any information welcome,
Regards,

Seth

Hi,

I can’t really read the code but I still try to look at the changeset with 
layman eyes

   /* success if at least one line and not a degenerate bounding box */
-  if(shape->numlines > 0 && (shape->bounds.minx != shape->bounds.maxx || 
shape->bounds.miny != shape->bounds.maxy))
+  if(shape->numlines > 0 && (layer_type == MS_LAYER_POINT || 
(shape->bounds.minx != shape->bounds.maxx || shape->bounds.miny != 
shape->bounds.maxy)))
 return MS_SUCCESS;
   else
 return MS_FAILURE;

I wonder two things:
What happens now if the layer type is not MS_LAYER_POINT?
What if layer is of type MS_LAYER_POINT and numlines=1, which means that the 
bounding box of the result set is just a point and minx=maxx and miny=maxy?

GetFeatureInfo and store the appropriate values to get you the order you want 
in them.

Then you can use runtime substitution in the DATA attribute to set the sort 
column based on the request type. E.g.

  DATA “... ORDER BY %request% ...”

You set validation on the the request accordingly. Might be some other SQL 
options to capitalize on.

Hi,

>From https://mapserver.org/mapfile/layer.html
"Inside a layer, only a single class will be used for the rendering of a 
feature. Each feature is tested against each class in the order in which they 
are defined in the mapfile. The first class that matches the its min/max scale 
constraints and its EXPRESSION check for the current feature will be used for 
rendering."

So in your example first geometry is rendered first with color 53 68 150 and 
the second one above it with color 188 34 115.

You wrote "I expect that the topmost feature returned in getfeatureinfo response
correspond to the topmost feature drawn on map". If you think of the rendering 
process, of yourself painting with brushes, the topmost feature on the map is 
the one that is painted last. If I understand it ight you would like to get a 
reversed order for GetFeatureInfo.

A workaround could be to make a copy of the layer you show on the map but with 
reversed sorting order. This layer would be used only for GetFeatureInfo 
requests. According to WMS specification QUERY_LAYERS must be a subset of 
LAYERS but if I remember right Mapserver is not strict with that and you could 
capture the GFT request on server side and change the name of the QUERY_LAYER 
on-the-fly. If Mapserver is strict, or you use some other server that follows 
the standard, you must also manipulate the request a bit more and add this 
extra layer into =.  Of course if you can control the client side you 
can make it to alter the GetFeatureInfo instead.

Another option could be to read the feature info with WFS GetFeature instead of 
WMS GetFeatureInfo. I also guess that heavy users of Mapserver will recommend 
you to use some MapScript dialect.

Be aware that Mapserver does not offer a real WYSIWYG experience with 
GetFeatureInfo. You can get also something what you do not see because 
Mapserver does not filter the GFI result by rendering rules like 
min/maxscaledenominators. I also believe that even if you have classes only for 
expression values 1 and 4 in your mapfile the GetFeatureInfo finds everything 
that appears in the data. I am not sure about this, though.

Hi,

hm, I would have expected the classes to be drawn in the same order as in the 
mapfile.

You could try to use the label-section with geomtransform 'labelpoint'
[1], perhaps mapserver there takes care of the mapfile order...

Another option would be to use grouped layers, I guess you found this
already:

Re: [mapserver-users] Need example of using a tabular select to retieve metadata for a label

[Lime, Steve D (MNIT)]

I think you’d have to associate geometries with the text regardless since 
MapServer will always apply a spatial filter (based on extent) in addition to 
whatever non-spatial filter you populate. I could see tying the extent of your 
project – either a rect or some fancy geometry to each bit of disclaimer text 
so the spatial filter would always evaluate to true. Might also be possible to 
use non-map coordinates. You see that typically with inline layers. I might 
have other ideas if you provided a bit more detail…

Aihe: [mapserver-users] Getting an empty MVT output for a point layer



I am using MapServer 7.2.0 to generate mvt for two layers (one line layer and 
one point layer). I am able to generate mvt output for a line layer but is 
having problem with a point layer. The mvt output is kind of empty (just 
contains layer name and column names). I am getting correct geojson outputs for 
both layers using WFS.



Here is the URL that I use to get MVT output:

mapserv?map=D:\home\site\wwwroot\100k_3857_node.map=tile=gmap=18+24+6=nodes=mvt



Here is the map file:



MAP

  CONFIG "PROJ_LIB" "D:\proj\SHARE"

  "gml_include_items"  "all"

  END



END



With almost an identical map file and an url (layer name and table name 
differ), I am getting a good mvt output for my line layer.



Any suggestions would be greatly appreciated.

Re: [mapserver-users] Status of MVT vector tiles?

[Lime, Steve D (MNIT)]

It generates vector tiles based on WMS requests. MapCache computes the proper 
extent based on the requested tile and then kicks off a WMS call for vector 
tile. The pull request creates support for a new generic “raw” format. MapCache 
doesn’t know much about files in this format, just a mime-type, so things like 
metatiling, image processing or tile assembly aren’t supported. You do get the 
cache management though. The raw format is not specific to vector tiles so you 
could use it for other formats like GeoJSON or UTFGrid.

Anyway, in my mapcache.xml file I have the following setup:



   mvt
   application/vnd.mapbox-vector-tile




  
http://mapserver.localhost/cgi-bin/mapserv?
  
  

  sna,wma,lakes,major_roads,places
  application/vnd.mapbox-vector-tile
  /Users/sdlime/work/mvt-demo/demo.map 

  




  wms_mvt
  g
  disk
  MVT


Then, if you look at the simple.json file in my demo repo you just change the 
source for the vector tiles layer to reference MapCache (I was running as 
FastCGI) instead of MapServer (mode=tile), so from:

"tiles": 
["http://mapserver.localhost/cgi-bin/mapserv?map=/Users/sdlime/work/mvt-demo/demo.map=tile=gmap={x}+{y}+{z}=all=mvt;],

to:

"tiles": 
["http://mapserver.localhost/cgi-bin/mapcache.fcgi/gmaps/mvt@g/{z}/{x}/{y}.mvt;]

One thing to note is that you can control the resolution that each tile is 
created at. Each tile has a grid associated with it and that is used to convert 
the features to a grid-based coordinate system. The higher the resolution of 
that grid the more detail is represented in the tile. The default is 4096x4096. 
You can change that value via the MVT output format, for example:

OUTPUTFORMAT
  NAME “mvt”
  DRIVER MVT
  FORMATOPTION “EXTENT=512”
END

A smaller resolution or extent will generally result in smaller tiles.

I found that pull request before thanks, will play around with it some more. 
When you say it relies on WMS requests does that mean it generates raster tiles 
or vector tiles in PBD file format? I don't have mine mapcache example working 
yet so i don't know what to expect.

About canceled requests i found related "issue" discussed on leaflet forum:
https://github.com/Leaflet/Leaflet.VectorGrid/issues/136
But i don't see a problem with that because all entities are loaded on my map.

I will have to find that secret souce yes, will try to optimize my map file for 
different scales. Pregenerated vector tiles would also help.

Thanks for your answers. Will track your github for further updates.
