Re: [MapServer-users] Data from MSSQL without extent

[Seth G via MapServer-users]

Hi,

You are probably looking for *wfs_use_default_extent_for_getfeature* (and 
setting to "false" in the LAYER METADATA) - see 
https://mapserver.org/ogc/wfs_server.html#layer-object

I ran into this myself as described in 
https://github.com/MapServer/MapServer/issues/5994

Re: [MapServer-users] setting COLOR of SVG symbol ?

[Seth G via MapServer-users]

Hi,

Unfortunately, I don't think this is currently possible, based on a previous 
reply from Steve Lime [1]:

I guess if it works in QGIS then it should be possible to implement this in the 
MapServer codebase too.

Re: [MapServer-users] WFS, OpenLayers and OUTPUTFORMAT explanations

[Seth G via MapServer-users]

Hi,

Probably best to check the WFS service GetCapabilities document to check which 
formats are supported. 
(From memory) wfs_getfeature_formatlist can include either the NAME or the 
MIMETYPE of the OUTPUTFORMAT.
You have MIMETYPE set to "application/json;subtype=geojson", so maybe try 
chaging this to "application/json" or changing the NAME from "geojson" to 
""application/json" to get an exact match.

Re: [MapServer-users] filter issues with WFS

[Seth G via MapServer-users]

Hi Carlos,

If you add DEBUG 5 to the LAYER, and set the CONFIG MS_ERRORFILE do you get 
more details in the logs for why the filter is failing?
The error indicates MapServer cannot parse the filter. The unencoded filter is 
shown below. 

http://www.opengis.net/fes/2.0; 
xmlns:gml="http://www.opengis.net/gml/3.2;>

  
   wkb_geometry

448849 197791
   
  
  http://www.opengis.net/fes/2.0;>
   wkb_geometry
   http://www.opengis.net/fes/2.0; name="geomFromWKT">

195673.1860001606531, 449272.4820001816079 195673.1860001606531, 
449272.4820001816079 200345.652186265, 447915.652115244

195673.1860001606531))
   
  



I'm guessing the geomFromWKT is not supported, so the filter should pass a GML 
Polygon object to filter by using an intersecting geometry. See 
https://mapserver.org/ogc/filter_encoding.html#tests for an example

Re: [MapServer-users] Pass time range in WCS 1.0.0 request GetCoverage

[Seth G via MapServer-users]

Hi Michał,

Looking at the code, I think this is an error in the documentation - time 
ranges in WCS 1.0 do not seem to be supported. There are no tests that cover 
time ranges either. 

You could use runtime substitution to create your own queries with custom 
parameters e.g. START_DATE=2022-03-10_DATE=2022-04-10 

The section at 
https://mapserver.org/ogc/wcs_server.html#spatio-temporal-indexes recommends 
using a TILEINDEX for the layer.

Re: [MapServer-users] CGI variable "map" fails to validate

[Seth G via MapServer-users]

Hi Matthew,

The CONFIG file I think is only reloaded when IIS or the Application Pool is 
restarted, so some changes to the regex may have been ignored. 
Do you have a sample request with the = parameter? Is there anything in a 
web.config file that could be stripping these out or modifying them?

Re: [MapServer-users] Why is Mapserver slower in Postgres 13 than in Postgres 11?

[Seth G via MapServer-users]

Hi Rob,

Are you using the same MapServer machine to make the queries?
If the MapServer version, and dependencies are all identical then the generated 
SQL queries should also be identical.
You wrote about "hitting the web page" - but if the requested extents are 
different then it is likely the client requests are different. Are you using 
WMS services? What do these requests look like?
Also you mention 4 different layers, so I'd try testing them one by one - are 
they all generating different SQL and response times?

Re: [MapServer-users] option to use sld in mapfile to configure layer styling

[Seth G via MapServer-users]

Hi Paul,

I think all the code functions are in place to do the bulk of this work, and 
this would be a nice addition to MapServer. Sharing SLD between applications is 
a huge benefit. If it is possible to apply SLD from a URL it should also be 
possible to apply SLD from disk. 

I wouldn't be a huge fan of embedding SLD directly in a Mapfile (although the 
CONNECTION parameter can accept large chunks of OGRVRTDataSource XML as long as 
quotes are escaped).

Re: [MapServer-users] filtering the data based on postgis attributes

[Seth G via MapServer-users]

Hi Marcin,

In these cases previously I've used a SQL trick to implement this, by setting a 
default value for the parameter (of a non-existent ID) and adding an OR clause 
to the SQL. E.g;

VALIDATION
"default_pid" "-1"
..

WHERE (pid  = %pid% OR %pid% = -1)

If no value is provided then the SQL will be WHERE (pid  = -1 OR -1 = -1) which 
will always return True so all records will return.

Re: [MapServer-users] PHP Mapscript: how to clone layers

[Seth G via MapServer-users]

Hi Jan,

I'm not a PHP MapScript user but you should be able to use:

$l2 = $l1->cloneLayer();

As per the note at the following link - "In the Java & PHP modules this method 
is named cloneLayer. "
https://mapserver.org/mapscript/mapscript-api/stub/mapscript.layerObj.html#mapscript.layerObj.clone

I'm guessing there is a clash with the a reserved keyword in PHP so the method 
needs a different name.

Re: [MapServer-users] Python MapScript - GEOS

[Seth G via MapServer-users]

Hi,

Testing the code here and the following line: shpObjBuffer = shpObj.buffer( 
0.0005 ) returns a valid buffered polygon:

>>> shpObjBuffer
 >
>>> shpObjBuffer.toWKT()
'POLYGON ((49.965857800020 8.16013072, 49

The buffer method [1] rerturns a new shape, so I'm not sure your check for a 
True value makes sense in this line:

 if shpObjBuffer == mapscript.MS_SUCCESS:

Are you sure the buffer isn't working?

Re: [MapServer-users] How to format labels on contours

[Seth G via MapServer-users]

Hi,

The MapScript API docs are back online - see 
https://mapserver.org/mapscript/mapscript-api/stub/mapscript.classObj.html#mapscript.classObj

The setText() method should give you what you need. Example (using Python):

s = mapscript.classObj(layer)
# other style and label stuff
s.setText('(tostring(([SQKM]),"%.0f")+" km2")')
# check the output using 
print(s.convertToString())

When using updateFromString it will replace everything in the classObj hence 
the error.

Re: [MapServer-users] Inconsistent support for template substitution

[Seth G via MapServer-users]

Hi,

This seems like a bug - there is a check to see if the Map projection is a 
geographic coordinate system [1], and if it is then it skips all the [maplon], 
[maplat], [minlon] etc. substitutions. If it is in another projection then the 
point and extent are reprojected to latlon and included in the template.

Re: [MapServer-users] creating a layer with PHP MapScript - shapes do not use classindex

[Seth G via MapServer-users]

Hi,

You could probably achieve this with the new SWIG MapScript. 

Alternatively how about creating an individual LAYER for each set of features 
with a single CLASS (I'm not sure how the CLASS is determined if the features 
have no attributes in the first place), and adding features to the relevant 
layer. 

If you then want to combine these into a single layer you could try a UNION 
LAYER [1], and use the STYLEITEM AUTO to pick up the styles from the layers.

Re: [MapServer-users] creating a layer with PHP MapScript - shapes do not use classindex

[Seth G via MapServer-users]

Hi,

The rendering code could be reassigning the classindex for the shapes based on 
their attributes. You will probably need to make sure the CLASS is assigned 
based on an attribute of the feature - e.g. add a CLASSITEM to the layer and 
add a value to the feature that will match the correct CLASS.

Re: [MapServer-users] symbol minsize/maxsize in mapServer 8

[Seth G via MapServer-users]

Hi Jörg,

I've been playing around with the MINSCALE etc. When using an OUTLINECOLOR you 
also need to set the MINWIDTH and MAXWIDTH on the SYMBOL to change sizes with 
resolution. I think this is the issue you were seeing in your example. 
For example to keep a constant outline width of 1 you can use the following:

STYLE
SYMBOL "circle"
SIZE 100
MAXSIZE 200
MINSIZE 12
COLOR "#F9A03F"
OUTLINECOLOR "#813405"
MINWIDTH 1
MAXWIDTH 1
END

There is a working example at https://app.mapserverstudio.net/#akyRvQvW - if 
you zoom in you will notice the circles get bigger (up to 200 pixels) but the 
outline width remains at 1 pixel.

Re: [MapServer-users] symbol minsize/maxsize in mapServer 8

[Seth G via MapServer-users]

Hi Jörg,

The STYLE MINSIZE and MAXSIZE are still valid Mapfile keywords - this was an 
error in the docs (and also came up on the dev list yesterday. This has now 
been corrected and the online docs fixed. 

I'm equally as confused as how exactly to use these. In your example what is 
your SYMBOL definition for "circle"?

I've not seen the OpenLayers template used for awhile - if could do with an 
upgrade to OL7!

Re: [MapServer-users] Call to StoredQuery successful as GET, but fails as POST request

[Seth G via MapServer-users]

Hi,

Are you able to log the SQL sent to Postgres and see the difference between the 
GET and POST request? Or maybe the query doesn't get to the database at all 
looking at that error. 
It looks like the filter is failing to convert to a Postgres query.

[MapServer-users] mappyfile is now an OSGeo Community Project

[Seth G via MapServer-users]

Hi all,

This month mappyfile became an official OSGeo Community Project [1]. To 
celebrate there is a v1.0.0 release, this drops Python 2.7 support, but 
includes over a year of fixes and improvements. Full release notes are at [2]. 

mappyfile is a Python library that allows you to easily create, edit, and 
format MapServer Mapfiles. Source code is on GitHub [3] and docs are at 
https://mappyfile.readthedocs.io/ and it is available on PyPI [4].

Any feedback or issue reporting welcome,

Seth

Re: [MapServer-users] Silent error running mapserver

[Seth G]

Hi,

Mapfiles are very portable between operating systems, with some possible edge 
cases as dependencies such as the regex library may vary, or a different code 
path is used on Windows which may render something slightly differently, or 
produce different line endings. 
It is more likely something changed between MapServer 7 and 8 which would cause 
this to break, possibly the change here [1]. It does sound like a bug though if 
an invalid SQL statement is created, and if a test case can be created it would 
be good to open an issue. 
In any case it is best to update to the new PROCESSING 'NATIVE_FILTER=id=234' 
format for Mapfiles in MapServer 8.0.

Re: [MapServer-users] Silent error running mapserver

[Seth G]

Hi,

How are you setting your "PROJ_LIB" path? It looks like it can't find the Proj 
SHARE directory. 
Are you able to share a Mapfile? Maybe try with a cut-down version - there are 
lots of custom parameters in your querystring (that shouldn't affect things, 
but a simpler test case would be easier to debug).

Re: [MapServer-users] mapserver: styling multiple stop colorrange for raster data

[Seth G]

A good question and it doesn't seem to be clearly documented. 
I've always tried values listed at 
https://mapserver.org/el/input/raster.html#raster-query even though that 
section appears to be written for MapScript. 
Each band has a value based on index, so you should get results using 
"value_0", "value_1", and "value_2" in RANGEITEM.
gdalinfo should peobably provide details on the value ranges in each band.

Re: [MapServer-users] mapserver: styling multiple stop colorrange for raster data

[Seth G]

Hi Trygve,

You can have multiple start/stop values and your syntax looks correct. Maybe 
you have multiple bands in your raster and you are symbolising on the incorrect 
value? Try explicitly setting the RANGEITEM. 

See working example at https://app.mapserverstudio.net/#9JBVADFh

CLASS
NAME "colorramp"
STYLE
COLORRANGE "#e3edfc" "#287593" # a color gradient from light 
grey to a shade of blue
# a pixel value of -20 will be light grey, and values from -20 
to 0 will be 
# assigned a color from the colour gradient of light grey to 
blue
DATARANGE -20 0
RANGEITEM "value_0" # this is the name of the value band in the 
raster, the datasets used in the Mapfile have a single band
END
STYLE
COLORRANGE "#29497b" "#759387"
DATARANGE 0 20
RANGEITEM "value_0"
END
STYLE
COLORRANGE "#bfa96d" "#480d26"
DATARANGE 20 50
RANGEITEM "value_0"
END
END

Re: [MapServer-users] Speed of WMS vs Speed of WCS; How to speed up WCS service?

[Seth G]

Hi Marcin,

As a first test I'd recommend adding in EXTENTs to all your layers (and 
ensuring they are correct):

EXTENT 1334552.857598 5342648.587634 4715044.821842 7547620.486088

If these are missing MapServer will often try and calculate these from the 
datasource automatically. Depending on the request type this calculation could 
be made multiple times.

Re: [MapServer-users] Some remote SVG files doesn't in 8.1

[Seth G]

Adding a width and height to the SVG also works, without having to remove the 
viewBox:

http://www.w3.org/2000/svg; width="10pt" height="10pt" 
viewBox="0 0 396.85 396.85">

Re: [MapServer-users] Some remote SVG files doesn't in 8.1

[Seth G]

Hi Martin,

The issue seems to be related to the viewBox property in the SVG file. 
If you save the SVG source from 
view-source:https://raw.githubusercontent.com/NordjyllandsTrafikselskab/gisimages/ca64d7a849c7cf0290ec41ec263a97b9195d0ff8/01.01.01.Bus.svg
 and remove the following text in a text editor the symbols display correctly:

viewBox="0 0 396.85 396.85"

Maybe it could be an upstream issue, or something has changed upstream that 
breaks symbol size calculations. 

Seth

Re: [MapServer-users] FW: Unable to build mapserver 8 on WIndows with v8 support

[Seth G]

Hi,

I've not used this functionality myself, and I remember at a MapServer 
codesprint there were problems trying to compile this over 5 years ago. In 
answer to your question about getting it working with MapServer 8 - I doubt 
this is possible without updating the source code. 

As Jeff wrote it will need someone to attempt to update this to work with newer 
versions. It would require experience of the v8 engine and its API changes in 
the last 10 years to get this working again. A few links that may be useful to 
get started:

- the code - 
https://github.com/MapServer/MapServer/tree/4b7ad75eda030eca919b7f7d06de8a8e95ca52f3/mapscript/v8
- the RFC about its implementation - 
https://mapserver.org/development/rfc/ms-rfc-106.html
- the original pull request - https://github.com/MapServer/MapServer/pull/4827

Just to note this support is to allow shapes to be manipulated with JS 
functions in a Mapfile, and unrelated to MapScript. Adding MapScript JS support 
is probably easier as it is one of the SWIG target languages.

Re: [MapServer-users] Qgis layer style file in mapfile

[Seth G]

Hi Steve,

I've so far only experimented with simple styles, but attempting to convert 
more complex examples from QGIS styles should highlight what type of style 
properties are missing in MapServer.

[MapServer-users] MapServer 8.0.1 release overview

[Seth G]

Hi all,

I've put together a summary of the changes introduced in the MapServer 8.0.1 
release from last month at 
https://mapserverstudio.net/posts/mapserver-8.0.1.html that could be of 
interest to MapServer users.

Re: [MapServer-users] Qgis layer style file in mapfile

[Seth G]

Hi Marcin,

Good timing with the question! There is currently a code sprint happening for 
the GeoStyler project [1]
This allows conversion between different styles including QGIS and MapServer 
Mapfiles.
If you are looking to convert from QGIS to Mapfile you need to use the 
geostyler-cli [2] to convert the QGIS style to the intermediary GeoStyler 
format and then use the GeoCat script [3] to convert this to a Mapfile. 
This is currently a fairly complex way do do things but we're looking at a 
Python wrapper to make this a simple one line command.

Re: [MapServer-users] Changing opacity of one layer in a multilayer WMS request URL with MapServer 8

[Seth G]

Hi,

I think OPACITY should still work at the STYLE level: 
https://mapserver.org/mapfile/style.html#mapfile-style-opacity
If you are using WMS then you could setup different styles with different 
OPACITY values, and then use named styles to select the appropriate style (with 
the STYLES= added to the WMS request).

Re: [MapServer-users] Using getMetadata with xml file

[Seth G]

Hi,

Did you set the metadata at the LAYER level?

LAYER
  NAME "testlayer"
  METADATA
'ows_metadataurl_href' "https://mapservice.test.org/data/Test.XML;
  END
END

Then a request to 
https://mapservice.test.org/cgi-bin/mapserv?map=/data/ows/maps/metatest.map=GetMetadata=testlayer
 should return the following HTTP response:

Status: 301 Moved Permanently
Location: D:\TFS\PublicLighting\Main\Python\plpy\mapfiles\generated\test.xml

Re: [MapServer-users] GetMap request inside python script; measuring speed of WMS?

[Seth G]

Hi Marcin,

Sorry I thought you wanted to do this within MapScript without a web server. 
If you want to simply make WMS requests to any WMS server over HTTP I'd 
recommend the Python library OWSLib, see for example 
https://geopython.github.io/OWSLib/notebooks/examples/wms.html

Re: [MapServer-users] GetMap request inside python script; measuring speed of WMS?

[Seth G]

Hi Marcin,

Have a look at the example Python script at 
https://github.com/MapServer/MapServer/blob/main/mapscript/python/examples/wxs.py
 - this shows creating and calling a WMS request.

Re: [MapServer-users] Symbol image on s3 bucket?

[Seth G]

Hi Marcin,

This is not currently possible (fopen is used to read these files [1]), but it 
would be a very nice feature to allow the GDAL virtual filesytems to be used 
for symbols (and maybe also fonts).

Re: [MapServer-users] WMS in 16bit depth?

[Seth G]

Hi Marcin,

Are you trying to display raster images with more colours?

You can play around with the OUTPUTFORMAT options - see details at 
https://mapserver.org/mapfile/outputformat.html
IMAGEMODE might be what you are looking for?

I've normally used these to reduce image sizes where possible. 

Seth

Re: [MapServer-users] WMS: Not all features show, depending on how I zoom and pan

[Seth G]

Hi,

Is there any change if you update the layer to have a single class with a 
simple line (no EXPRESSION, LABEL, MAXSCALEDENOM)?

E.g.

CLASS
STYLE
COLOR 0 0 255
WIDTH 6
END

Re: [MapServer-users] Swig Mapscript Still Fails to Build with PHP 8

[Seth G]

Hi,

The CI setup for MapServer doesn't test Homebrew/Mac, so that could be one 
possible issue.

MapServer 8 and PHP 8 however is tested on Linux - see 
https://github.com/MapServer/MapServer/blob/main/.travis.yml and the most 
recent log for PHP 8 - 
https://app.travis-ci.com/github/MapServer/MapServer/jobs/583600218
Lots of the install logic run on Travis is contained in 
https://github.com/MapServer/MapServer/blob/main/ci/travis/before_install.sh
Check for differences with your own logs to see what might be causing the 
errors.
Good luck!

Seth

[MapServer-users] MapServer at FOSS4G 2022

[Seth G]

Hi all,

FOSS4G was held in Florence/Firenze last week [1], and included a "State of 
MapServer 2022" talk [2]. 
The slides for this can be seen online [3]. The source HTML for this 
presentation is available on GitHub [4] - please feel free to reuse and adapt 
this content for any MapServer related talks. 

The MapServer ecosystem is wide and growing, so if there are new tools and 
systems that would be of interest to MapServer users please raise awareness of 
them on this user's list, and via the MapServer Wiki, and they can be mentioned 
in any future MapServer updates. 

7 members of the PSC (Project Steering Committee) were present, and from 
general discussions MapServer is widely used across many countries and 
organisations. Please add to the MapServer Site Gallery [5] if possible! 

Below is a selection of other MapServer related presentations - I believe the 
slides and audio for these will be published on YoutTube later this year:

+ MapServer - Make beautiful maps - 
https://talks.osgeo.org/foss4g-2022/talk/SQMVXH/ (slides at 
https://github.com/LarsSchy/FOSS4G-2022)
+ Mapserver layer handling, production, and management in larger scale 
environment - https://talks.osgeo.org/foss4g-2022/talk/CXXKVU/
+ A crawler for spatial (meta)data as a base for Mapserver configuration - 
https://talks.osgeo.org/foss4g-2022/talk/QW3NYC/
+ EVRYMAP - An extensible web mapping framework based on Angular, NodeJS, 
Leaflet and Mapserver - https://talks.osgeo.org/foss4g-2022/talk/Q9G7EH/

Last year's online talk "State of Mapserver 2021" is also available on YouTube 
[6] and covers many of the new features arriving in MapServer 8.0.

Re: [mapserver-users] [SURVEY] Publishing of Twin Cities, OSGeo Local Chapter Meeting Recordings

[Seth G]

Hi Bob,

There is an OSGeo YouTube channel at 
https://www.youtube.com/channel/UCDvJEf8hXbyeVqaYaS8sLvw that could be used?
I'd like to highlight a couple of the MapServer related talks at the MapServer 
summary talk next month at FOSS4G if possible. As you mention, the 
presentations linked to at 
https://www.osgeo.org/local-chapters/twin-cities-mn-usa-chapter/ are currently 
offline, so +1 from myself.

Re: [mapserver-users] Fwd: MapServer 7 arithmetic expressions do not work on STYLE attributes?

[Seth G]

Hi,

Couldn't you just add a new field to the DATA clause and use that?

`DATA "geom from (select pk, geom, size, (size * 2) as mycolor from 
sizes_of_thing) USING srid 3788 version 11g" `
`CLASS `
`MAXSCALEDENOM 5001 `
`STYLE `
`COLOR [`mycolor`]`

Or maybe this is a cut-down example.

Re: [mapserver-users] MapScript import errors (Module not found) in Python venv with global install

[Seth G]

Glad it's working for you, and good to know it can work alongside QGIS. 
The GISInternal Python MapScripts I think are built with SWIG 2.0, whereas I 
compiled those wheels with the latest version of SWIG 4.0.2/master build. That 
may explain why the GISInternals don't work with more recent Python versions.

Re: [mapserver-users] MapScript import errors (Module not found) in Python venv with global install

[Seth G]

Hi,

As you wrote, the version of Python needs to match the version of Python used 
by GISInternals (which is different dependent on the package) e.g. 
https://www.gisinternals.com/packageinfo.php?file=release-1928-x64-gdal-3-4-2-mapserver-7-6-4.zip
 - "python - Python37-AMD64"

Is everything working fine until you setup a virtual environment? This could be 
because activating a Python virtual environment on Windows seems to wipe out 
any previously set environment variables in the session. Try activating the 
virtual environment, and then running SDKShell.bat (or simply setting the 
environment variables you need from that file).

SET PATH=C:\MapServer\bin;%PATH%
SET PROJ_LIB=C:\MapServer\proj7\SHARE
SET MAPSERVER_DLL_PATH=C:\MapServer\bin

I have some experimental MapScript Wheels [1] built for various versions of 
Python with a recent MapServer development build, which could work with a 
release-1930-x64 development build [2].

Re: [mapserver-users] MapScript import errors (Module not found) in Python venv with global install

[Seth G]

Hi Maëlle,

MapScript (and MapServer) use many of the same dependent DLLs as QGIS - GDAL, 
Proj, GEOS etc. which would then get loaded into memory by Python. 
For everything to work correctly, all these dependencies would have to be the 
same version, and (I think this is still the case), compiled with the same 
version of Microsoft Visual C (the 1928, 1931 etc. use when naming the 
GISInternals zips). 
It probably would be possible to get everything build and working, but you'd 
likely have to compile everything yourself. 
Is it possible to modify your workflow so a PyQGIS environment dumps out data 
to disk and then a MapScript environment works on this data? 
I'd imagine PyQGIS can probably do everything MapScript can, except for 
manipulate Mapfiles - you could take a look at mappyfile for this, which is 
Python only has has no dependent DLLs.

Re: [mapserver-users] Mapscript Python module version 7.6.0 not working with Python 3 > 3.6

[Seth G]

Hi,

The wheels at https://pypi.org/project/mapscript/ are only available for 
Windows [1]. There is also a source distribution, but it would also require the 
MapServer soource and dependencies to build. 

Universal Wheels for Linux would only be possible by using manylinux [2], but 
I've not been able to compile MapServer with this. 
For other options (including creating your own Linux Wheels for your MapServer 
builds that can be installed in a virtual environment) see the sections 
"Installation on Unix" and "Building the Mapscript Module" at 
https://pypi.org/project/mapscript/

Re: [mapserver-users] dynamic ows_serviceurl

[Seth G]

Hi Paul,

The runtime substitution and setting a querystring on the server is a good 
approach - have you found any drawbacks to this? Most web servers can set/add 
querystrings without any need for further software. 

As Steve mentioned the alternative would be to generate Mapfiles for specific 
environments from a template.
I use mappyfile for this, with a Python script that can be run as part of 
continuous deployment:

import mappyfile
mapfile = mappyfile.open("original.map")
# update the web metadata settings
mapfile["web"]["metadata"]["ows_onlineresource"] = 
"https://example.com/cgi-bin/mapserv?map={}.map".format("test") 

mappyfile.save(mapfile, "new.map")

Typical other settings I'd change are connection strings, DEBUG level, and 
EXTENTs for different Mapfiles.

[mapserver-users] Securing MapServer Deployments

Hi all,

I've written a blog post on Securing MapServer Deployments at 
https://geographika.net/posts/securing_mapserver.html which also includes 
details on the new CONFIG file available in MapServer 8.0
If anyone has any other tips or best practices around security, please send 
them on to the list,

Re: [mapserver-users] How to avoid reading unneeded Features from PostGIS when displaying by map scale ranges?

[Seth G]

Hi Kyle,

Take a look at LAYER SCALETOKEN - 
https://mapserver.org/mapfile/layer.html#mapfile-layer-scaletoken
and the RFC https://mapserver.org/development/rfc/ms-rfc-86.html#rfc86 

You should be able to add a filter directly to the DATA clause based on the 
scale that would filter the data directly at source.

Re: [mapserver-users] mapserv cli and run-time substitution

[Seth G]

So does the following also work? Without quotes should mean it is treated as a 
number:

EXPRESSION ([year] = %year%)

Re: [mapserver-users] mapserv cli and run-time substitution

[Seth G]

Ah ok I was looking at the mapfile. Passing =1976 in from the command line 
should work fine.
Maybe the value is being treated as a string, so you could test if the 
following worked (equals rather than less than):

EXPRESSION ("[year]" = "%year%")

Also maybe try with a different parameter name e.g. MYYEAR just in case YEAR is 
treated differently as it is used for various OGC services.

Hi,

Shouldn't the variable be wrapped in percentage signs?

EXPRESSION (%year% < 1976)

Re: [mapserver-users] WFS bbox/intersect etc query from custom projection to EPSG:4326

[Seth G]

Hi Sander,

Does adding a PROJECTION block to your LAYER have an effect?
Even if the layer projection is the same as the MAP I think I've run into a few 
combinations where setting explicitly on the layer helped.

Re: [mapserver-users] Corrupted PNG issue

[Seth G]

Yes apologies John for hijacking the thread, I thought it could be related to 
your issue but looking less and less likely.
Steve's suggestion to use the commandline mapserv -nh "QUERY..." approach 
should rule out a few more issues. 

Even - the same zip cannot be opened on Linux either (using Ark and unzip): 
"9487 extra bytes at begging or within zipfile". 
The GDAL within the build (3.3.3) creates a zip of the WFS just fine for the 
same layer/WFS service using ogr2ogr:

ogr2ogr -f "ESRI Shapefile" "H:/Temp/test.shp.zip" 
WFS:"https://server/mapserver/?service=WFS=GetFeature=2.0.0 
<https://plmonaghandev.compass.ie/mapserver/?service=WFS=GetFeature=2.0.0>"
 LayerName -overwrite -skipfailures

GDAL 2.4.4 doesn't create zips so it must be MapServer doing the zipping in 
this version at least?
I'm guessing this points to a MapServer issue, so I'll carry on debugging.

Re: [mapserver-users] Corrupted PNG issue

[Seth G]

Thanks Even, I'll give that a go (the bisect worked well for another issue a 
few months ago). 

I presume the zipping issue is more likely to be in the MapServer codebase than 
in GDAL?
The GISInternals did switch from GDAL 2.4.4 to GDAL 3.3.3 from the 7.4.3 to 
7.6.4 branches.

The zip exports work fine over a web browser rather than command line which is 
strange. Maybe its related to modifications to the -nh switch.

Re: [mapserver-users] Corrupted PNG issue

[Seth G]

Possibly unrelated but I ran into a similar issue exporting WFS to zipped 
shapefiles.
Working fine in 7-4-3 but broken in 7-6-4 (and current master) - the zip files 
are corrupt, although they have an identical size. 

7-zip reports "Headers Error Unconfirmed start of archive"

The same command is used for both versions:

mapserv -nh 
"QUERY_STRING=map=my.map=WFS=GetFeature=LayerName=2.0.0=shapezip=EPSG:3857"
 > output.zip

I had a look with a hex editor but the start of the working and corrupt zips 
seem identical. 

On the other hand all PNGs / WMS services are fine.

Re: [mapserver-users] Apply styling for MVT from using .map file

[Seth G]

Hi,

You should be able to use GeoStyler to do style conversions:

https://github.com/geostyler/geostyler-mapfile-parser - MapFile to GeoStyler
and then https://github.com/geostyler/geostyler-openlayers-parser - GeoStyler 
to OpenLayers

There are a couple of FOSS4G talks on GeoStyler that might be a useful 
introduction:

[mapserver-users] State of MapServer 2021 Slides

[Seth G]

Hi all,

For those who weren't able to attend FOSS4G this year the slides of the State 
of MapServer 2021 presentation can be found at 
https://geographika.github.io/mapserver-state-2021/

Also of interest to MapServer users are:

Mapserver – Labeling and Circles – my best tips and tricks [1]
Geostyler Mapfile Parser [2]

I believe the talks will all be published online in around a month.

Re: [mapserver-users] Mapscript C# and OWSRequest parameters

[Seth G via mapserver-users]

Actually as there are no URL limits with MapScript you should be able to add 
your filter as a WFS GET parameter and skip using POST requests altogether.

Re: [mapserver-users] Mapscript C# and OWSRequest parameters

[Seth G via mapserver-users]

Hi Jelmer,

There is no issue using MapServer to handle WFS POST requests, but it seems as 
though this functionality was never implemented for the MapScript bindings. 

See links:

https://github.com/MapServer/MapServer/issues/1788#issuecomment-42658553

> To implement this, we would need to actually implement the msIO_bufferRead()

> 
And also https://github.com/MapServer/MapServer/issues/2681#issue-3960720

So two options - 1) add in the functionality for msIO_bufferRead (which would 
be a nice addition to MapServer), or 2) use the other MapScript querying 
mechanisms as documented at 
https://geographika.github.io/MapServer-documentation/mapscript/querying.html

Re: [mapserver-users] Mapscript C# and OWSRequest parameters

[Seth G]

Hi Jelmer,

I think you'd have to use mapscript.msIO_installStdinFromBuffer to read data in.
See https://mapserver.org/development/rfc/ms-rfc-16.html#io-hooking although 
I'm not sure if the approach works or was fully implemented.
Let us know how you get on,

[mapserver-users] Embedded LEGEND Transparency

[Seth G]

Hi all,

The LEGEND TRANSPARENT keyword [1] has been deprecated since version 4.6 of 
MapServer and was planned to be removed for version 8.0.

However, there is a use case which I can't recreate using the OUTPUTFORMAT 
TRANSPARENT ON setting. 

The MAP itself has an IMAGECOLOR e.g. 255 200 0 (yellow), however an embeded 
LEGEND should be TRANSPARENT. 
Setting TRANSPARENT ON in the OUTPUTFORMAT makes both map and legend 
transparent. Leaving it off and the map and legend both have yellow 
backgrounds, and the area under the legend is no longer visible. 
This is one of the test cases [2] in msautotest. A similar issue seems to apply 
to SCALEBAR. 

Does anyone have a way to recreate this?
If not then it probably makes sense to un-deprecate the TRANPARENT keywork for 
LEGEND and SCALEBAR.

I've not used it but the following might help for the AGG/PNG driver:

The default is 6.

Re: [mapserver-users] differing image size with different mapserver versions

[Seth G]

Hi Richard,

In your OUTPUTFORMAT declaration maybe try setting the DRIVER to *AGG/PNG8*
Also  IMAGEMODE PC256 was only for GD support that was removed in 7.0. Try 
IMAGEMODE RGB (or RGBA if you want transparency).

 But this predates 6.4 release by several years, so this doesn't explain 
 why you see a different behavior, unless something in 6.4 still turned on 
 interlacing on in that configuration.

 From what I can see in the doc, the interlacing mode was removed in the 
 7.0 release when GD went off, so I don't think you can do much. I guess 
 that could be re-added but would require some coding.

[mapserver-users] Mapfile syntax changes and XML support

[Seth G]

Hi all,

The MS RFC 133: Mapfile Syntax Cleanup [1] proposes the removal of a number of 
deprecated Mapfile keywords. Once in place these keywords will no longer be 
valid and will throw errors in the Mapfile parser. Some of these keywords no 
longer have an effect, and the others have a better alternative. 

We are interested in finding out how much usage there is of the Mapfile XML 
support [2], introduced via RFC 51 in MapServer 6.0 [3], and whether the 
Mapfile XSD [4] and Mapfile XSL [5] files need continued maintenance. 

There is also a Mapfile DTD [5] which is likely to be removed, and has not been 
keep up to date over the years.

Re: [mapserver-users] Mapserver installation in cloud environments (kubernetes)

[Seth G]

There was an interesting talk on running MapServer on Amazon Lambda - 
https://www.youtube.com/watch?v=g_WMDxsuCfk=2s
The CGI approach of MapServer scales well as each request can be run separately 
(at a slight overhead for database connections, PROJ startup etc).

[mapserver-users] GeoJSON Date Anomalies

[Seth G]

Hi,

I'm getting some strange date formatting anomalies when returning GeoJSON from 
MapServer. It might be more of a GDAL issue than MapServer. 

Using MapServer from the main branch (7-7) and gdal302.dll - the exact same 
MapServer setup returns dates with different formatting dependent on the 
machine. 

Dates on a local machine have T, dates on the server do not:

- Windows 10 local: "LastUpdatedDateUtc": "2021-04-20T10:33:31.626"
- Windows 2019 Server: "LastUpdatedDateUtc": "2021-04-20 10:33:31.6259376" 

Data is coming from the MSSQL Driver and database requests are identical. WFS 
requests are also identical for the test. 

OUTPUTFORMAT block below:

OUTPUTFORMAT
NAME "geojson"
DRIVER "OGR/GEOJSON"
MIMETYPE "application/json; subtype=geojson; charset=utf-8"
FORMATOPTION "FORM=SIMPLE"
FORMATOPTION "STORAGE=memory"
FORMATOPTION "LCO:NATIVE_MEDIA_TYPE=application/vnd.geo+json"
END

Has anyone else experienced this? Does a machine locale affect date formats?

Re: [mapserver-users] Layer Attribute Metadata

[Seth G]

Hi Steve,

The output would look something like the output in 
https://inspire.ec.europa.eu/schemas/au/4.0/AdministrativeUnits.xsd




-- Name -- upper level unit -- Definition -- A unit established at a higher 
level of national administrative hierarchy that this administrative unit 
administers. -- Description -- NOTE Administrative units at the highest level 
of national hierarchy (i.e. the country) do not have upper level units. 
CONSTRAINT Each administrative unit at the level other than '1st order' (i.e. 
nationalLevel <> '1st order') shall refer their upper level unit.


au:AdministrativeUnit
au:lowerLevelUnit




Maybe this is part of the ISO standard used by GetLayerMetadata - 
https://mapserver.org/ogc/layer_metadata.html ?
WFS GetFeatureType doesn't seem to have a description field - 
http://schemas.opengis.net/wfs/2.0/examples/DescribeFeatureType/DescribeFeatureType_Example01_Response.xsd

It seems a missed opportunity not to be able to document fields alongside 
autogenerated type/nillable information from the source.

[mapserver-users] Layer Attribute Metadata

[Seth G]

Hi all,

Is anyone aware of any OGC service which can return comments for a layer 
attribute/field?
The WFS DescribeFeatureType [1] seems the most likely candidate but has no 
"description" or equivalent property at the attribute level. Attributes are 
returned as follows:



The docs for the WFS layer object 
https://www.mapserver.org/ogc/wfs_server.html#layer-object allow the following 
to be set for each attribute:

gml_[item name]_alias
gml_[item name]_precision
gml_[item name]_type
gml_[item name]_value
gml_[item name]_width

It would be nice if there was an option to set something like the following, 
and have it returned as part of the layer metadata:

gml_[item name]_description

This way the automated parts of the attribute (type, precision etc.) could be 
included along with a description of what the field contains. 

Does anyone have a way of handling this with MapServer?

Seth

Re: [mapserver-users] How to use MS_ENCRYPTION_KEY with AWS connection

Hi Jaime,

I believe the encryption key can only be used for some connection types (I know

following as supported:

OGR
Oracle Spatial
PostGIS
SDE

Re: [mapserver-users] Mapscript circular import error inside Python-Flask Docker

[Seth G]

Hi Aditya,

Are you building MapScript yourself or using "sudo apt-get install 
python-mapscript" - see notes under "Installation on Unix" at 
https://pypi.org/project/mapscript/

"This happens only when I have the Python VENV activated when running outside 
Docker" - do you mean the exact same approach works outside of Docker? Is 
MapServer installed on Docker (this is required along with mapscript)?

Python 3.9 is as yet untested/supported, but this may not be the cause issue.

Re: [mapserver-users] Please add your site/services to the MapServer gallery

Good to push this Jeff. 

One question - are non-public sites desired/eligible for this list?
There are plenty of internal/Intranet systems relying on MapServer, but without 
a public URL we may not want them on the wiki.

Re: [mapserver-users] PHP MapScript request handling gives seg fault error in libgdal

[Seth G]

Hi Rob,

More details on the PROJ6 performance implications at 
https://www.mapserver.org/development/rfc/ms-rfc-126.html#performance-implications

As Jeff wrote if you can recreate with shp2img or mapserv then it can rule out 
MapScript. A minimal MAP file and dataset would then be required to debug 
further. 

Do you create a new mapscript.OWSRequest() object for each request?

[mapserver-users] Layer Metadata Questions

[Seth G]

Hi all,

I've been looking at using the Layer Metadata as described at 
https://mapserver.org/ogc/layer_metadata.html

"MapServer’s layer API supports the ISO 19115:2003 geospatial standard" - 
although looking at https://www.iso.org/standard/26020.html this has now been 
withdrawn and replaced with ISO 19115-1:2014 - 
https://www.iso.org/standard/53798.html
I presume there is not much difference between these 2 schemas? There is a ~180 
EUR charge to get a copy of the PDF. 
The source code has a comment "Generate an ISO 19139:2007 representation of 
layer metadata " [1] - so maybe the docs need an update?

The second question regards the mapping of the LAYER METADATA block to the ISO 
output. There is a good test and expected output at [2] and [3]. 
Looking at the code it appears the "contact" metadata can only be retrieved at 
the MAP rather than LAYER level [2]. 
Is this something that should be available at LAYER level also, perhaps using 
"wms_attribution_title"?

Any comments appreciated,

Seth

Re: [mapserver-users] Setting a connection host from ENV

[Seth G]

Hi Ben,

The only environment variables used by MapServer are listed here [2]
For updating other parameters I think you only have 2 choices:

1. Use runtime substitution 
https://mapserver.org/cgi/runsub.html#parameters-supported
2. Create deployment specific Mapfiles. There are a few choices for this - sed 
as you mentioned, but also MapScript. For a similar situation I use mappyfile 
[1] (a Python Mapfile parser).

Re: [mapserver-users] PostGIS query problem

[Seth G]

Hi,

What client are you using?
How long does the query take to complete?
It is likely the client stops waiting for a response.

Re: [mapserver-users] Differerent output format for GetFeatureInfo - template strategy

[Seth G]

Hi,

I'm not sure if you have a custom template for each layer already, or if this 
something you want to avoid?

I'm guessing ideally you want to be able to change the LAYER - TEMPLATE via the 
URL?
Although this is not listed in the docs at 
https://mapserver.org/cgi/runsub.html#parameters-supported looking at the 
source I think it can be replaced via a URL. 

You can also set a CLASS TEMPLATE via the URL, and maybe have a different CLASS 
for each INFO_FORMAT and select it with GetStyles. 

Changing the format filename for each layer might be a possibility?
https://mapserver.org/cgi/runsub.html#parameters-supported
OUTPUTFORMAT: FORMATOPTION: FILENAME (must have a MAP VALIDATION pattern)

[mapserver-users] Implementing a WMS ORDERBY Parameter

[Seth G]

Hi list,

Following on from a discussion on implementing a SORTBY parameter for WMS 
requests on the dev lists [1], I have a workaround that may be useful to some. 

This resolves WMS image requests producing different results if a consistent 
feature order isn't applied. A sort order can be hardcoded into a LAYER DATA 
clause, but this then means sorting using a WFS SORTBY parameter to the same 
layer is ignored. 

My current solution is to add a new runtime-substitution parameter (with 
validation to check for a single word) and then add this dynamically to an 
ORDER BY clause. The trick is to add a ORDER BY (SELECT NULL) as the default 
value for any requests to the layer not using the parameter. I'm not sure how 
different database drivers implement this in the DATA clause so it may need 
some tweaking. The example below works with the MSSQL driver. 

DATA "GEOM FROM (
SELECT *
FROM myview
) 
AS tbl USING UNIQUE fid USING SRID=3857 ORDER BY %ORDERBY%"

VALIDATION
"ORDERBY" "(^[A-Za-z]+$)"
"default_ORDERBY" "(SELECT NULL)"
END

A client WMS can then simply add ORDERBY=MyFieldName to ensure consistent 
results.

[mapserver-users] Filter could not be translated to OGR filter

[Seth G]

Hi all,

I've run into a strange issue when using a WFS filter with spaces and an 
OGRCONNECTION. 
I think I've narrowed it down to involving the following:

1. Using OGR CONNECTION (the filter is fine when using MapServer Shapefile 
connection) with a shapefile
2. Via a web server (I'm using IIS)

The following WFS filter:

http://www.opengis.net/fes/2.0 
http://schemas.opengis.net/filter/2.0/filterAll.xsd 
http://www.opengis.net/gml/3.2 http://schemas.opengis.net/gml/3.2.1/gml.xsd; 
xmlns:fes="http://www.opengis.net/fes/2.0; 
xmlns:gml="http://www.opengis.net/gml/3.2; 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance;>name*Old
 T*

Returns this error:


msWFSGetFeature(): WFS server error. 
FLTApplyFilterToLayer() failed
msOGRFileNextShape(): OGR error. OGR GetNextFeature() error'd. Check 
logs.
  

Within the filter it is the Literal tag that has a problem - whenever the 
literal tag is greater than a certain number of characters. 

The following work:

* R*
* O*
*Old*
*Fic*

The following breaks the filter:

*Ficc*
*Oldt
Old (a strange one as it is fewer characters than 
others)

I cannot recreate the issue using the command line passing in the exact same 
content, so I think it could relate to encoding of the filter in the POST 
request. I'm using "Content-Type: application/x-www-form-urlencoded; 
charset=UTF-8" other types give parsing errors e.g. msOWSPreParseRequest(): OWS 
error. XML parsing error: Start tag expected,  not found

Perhaps the encoding makes the literal tag too long somewhere in OGR?

Any insights appreciated,

Seth

Re: [mapserver-users] wfs_features_cache_count and GeoJSON output

[Seth G]

Thanks Even!
I've tried the test case locally and I get the same error (for both WFS 1.0.0 
and 2.0.0), so it looks like it could be a Windows issue. Default GML output is 
fine. I'll do some debugging and post any findings.

[mapserver-users] wfs_features_cache_count and GeoJSON output

[Seth G]

Hi all,

Has anyone any experience of using the "wfs_features_cache_count" setting as 
documented at https://mapserver.org/ogc/wfs_server.html#index-20 ? Related 
commit at [1]. 
This works fine with the default GML output, but I get the following error 
using GeoJSON output:


http://www.w3.org/2001/XMLSchema-instance; 
xmlns:ows="http://www.opengis.net/ows/1.1; version="2.0.0" xml:lang="en-US" 
xsi:schemaLocation="http://www.opengis.net/ows/1.1 
http://schemas.opengis.net/ows/1.1.0/owsExceptionReport.xsd;>
  


Output format block in the Mapfile:

OUTPUTFORMAT
NAME "geojson"
DRIVER "OGR/GEOJSON"
MIMETYPE "application/json; subtype=geojson; charset=utf-8"
FORMATOPTION "FORM=SIMPLE"
FORMATOPTION "STORAGE=memory"
FORMATOPTION "LCO:NATIVE_MEDIA_TYPE=application/vnd.geo+json"
END

I'm just wondering if this is expected when using a non-standard output, a 
configuration problem, or an issue.
Thanks for any insights,

Seth

Re: [mapserver-users] Question about python mapscript and point style.

[Seth G]

Hi,

The following example works for me - 2 styles are in the output Mapfile. Maybe 
there is an issue elsewhere?
Is there a Python error, or is the output not what you are expecting?

import mapscript

m = mapscript.fromstring("""
MAP
 LAYER
 NAME "test"
 TYPE POINT
 CLASS
 NAME "0"
 STYLE
 COLOR 0 0 0
 SYMBOL 1
 SIZE 13
 END
 END
 END
END
""")
lyr = m.getLayerByName('test')
cls = lyr.getClass(0)
style = mapscript.styleObj()
style.color.setRGB(0, 0, 0)
style.symbol = 1
style.size = 3
cls.insertStyle(style)
print(m.convertToString())

For Mapfile manipulation in Python you could also try 
https://pypi.org/project/mappyfile/

Seth

Re: [mapserver-users] Question about python mapscript and point style.

[Seth G]

Hi Vladimir,

Could you try the following syntax?

new_style = new mapscript.styleObj()
new_style.symbolname = 'circle'
new_style.size = 10
the_class.insertStyle(new_style)


Also make sure your variables aren't overriding the class names - e.g. maybe 
use different variable names than classObj. 

Regards,

Seth

Re: [mapserver-users] MapServer Rest API

[Seth G]

Hi Damien,

So the REST API is more for modifying Mapfiles rather than accessing data?
The latter looks like it will gradually happen with the implementation of the 
OGC Features API.
See https://github.com/geopython/pygeoapi for an example. 

I've not heard of https://github.com/neogeo-technologies/mra before. Looks like 
there was a recent bug fix so maybe still active? I'm unaware of any others. 

I sometimes make dynamic maps by storing a Python dict object and manipulating 
it based on requests and using https://mappyfile.readthedocs.io to write back 
to a Mapfile.

Re: [mapserver-users] Lost the transparency after a SO Update

[Seth G]

Actually that does remind me of a recent issue I had when updating from 7.2 to 
7.4. I have the following diff:

 STYLE
 # add an almost fully translucent colour
 # setting the aa value to 00 in the rrggbbaa setting causes any masked layers 
to no
 # longer display
 COLOR "#FF01"
 END

The above no longer worked and I updated to:

 STYLE
 # add an almost fully translucent colour - if no colour then no MASK
 COLOR "#ff"
 OPACITY 1
 END

Re: [mapserver-users] Lost the transparency after a SO Update

[Seth G]

Hi Andrea,

Do you have a cut-down Mapfile to reproduce this?
Are you using the COMPOSITE block to set OPACITY?
https://mapserver.org/mapfile/composite.html#parameters
Setting OPACITY on the layer directly is deprecated since 7.0

Re: [mapserver-users] Highly inefficient MakeValid statement in Mapserver-generated spatial queries

[Seth G]

Hi Istvan,

Unfortunately you won't be able to turn it off without recompiling the MSSQL 
driver. 
I've added a pull request removing these at 
https://github.com/mapserver/mapserver/pull/5856
This will be merged into master assuming there are no objections. 
I assume you are using ms4w as you mention a 4.0.1 release? You'll need to see 
when a new release of that may be available with the update. 
Thanks for reporting this issue,

Seth

Re: [mapserver-users] Highly inefficient MakeValid statement in Mapserver-generated spatial queries

[Seth G]

Hi,

Good question. This is a fairly new change as part of 
https://github.com/mapserver/mapserver/issues/5781 from April this year. 
In SQL Profiler I seem to get GEOM.STIntersects for WFS requests and 
GEOM.MakeVaid().STIntersects for WMS. 
MakeValid does appear to stop the index being used. Do you have a link which 
says this definitively?

Do you get the same error if you use the full path to FONTSET  in your Mapfile?

[mapserver-users] State of MapServer 2019 FOSS4G Presentation

[Seth G]

Hi all,

The State of MapServer presentation from FOSS4G 2019 in Bucharest yesterday has 
been uploaded to 
http://geographika.net/presentations/mapserver-foss4g2019/index.html
There should be plenty of links to click on and follow up. 
Hopefully there are a few new subscribers to this mailing list since yesterday 
- if so welcome!

[mapserver-users] FOSS4G 2019 MapServer Talks

[Seth G]

Hi all,

Next week in Bucharest FOSS4G 2019 is taking place. On Wednesday 28th of August 
(16:30-18:00 in the Opera room) we have a whole session of MapServer talks!

- State of MapServer: Seth Girvin, Daniel Morissette, Michael Smith
- MapServer, Optimize for performance: Lars Schylberg
- MapML: The (new) "map" HTML element, now in MapServer, GDAL and OGR: Daniel 
Morissette, Peter Rushforth

See https://2019.foss4g.org/schedule/full-schedule/ for details. 
I believe the sessions will also be recorded (and possible live-streamed) if 
you won't be there in person. 

After the talks we have booked the room for a "Birds of a Feather" meeting as 
an opportunity for users and devs to get together for a general discussions 
about MapServer's past, present and future, so please join us. 

Please feel free to add your names to the wiki page at 
https://wiki.osgeo.org/wiki/FOSS4G_2019_BirdsOfAFeather#Opera or reply on this 
list. 

Seth

Re: [mapserver-users] Forward time and other parameters to a layer defined as wms client

[Seth G]

A related approach to the one suggested by Trond is the one mentioned in 
https://github.com/mapserver/mapserver/issues/4797

MAP->WEB: METADATA (values only, not keys) are supported as runtime 
substitution parameters - see 
https://mapserver.org/cgi/runsub.html#parameters-supported

So if hardcoding wms_time works then in theory this could be replaced with a 
dynamic value from a URL. 
I'm unsure if TIME would need to be added to the VALIDATION block as it is 
already a standard WMS parameter.

Re: [mapserver-users] Forward time and other parameters to a layer defined as wms client

[Seth G]

Hi Søren,

Just to clarify you are using MapServer as a WMS Client as outlined here 
https://mapserver.org/ogc/wms_client.html
With "CONNECTIONTYPE WMS"?

Re: [mapserver-users] Combining WMS Filter and Style Parameters

[Seth G]

Hi Daniel,

Probably good news it is a bug rather than an unsupported option which didn't 
fit with the current MapServer codebase. 
The WMS filtering is an excellent feature - it also provides a method for 
filtering vector tiles via a WMS interface,

I've added a test case to the likely-related issue at 
https://github.com/mapserver/mapserver/issues/5744#issuecomment-517277267
