Re: [mapserver-users] enabling browser cache from Mapcache?

[Dan Little]

Please take a moment to do a bit more reading about how browser caching
works:
-
https://developers.google.com/web/fundamentals/performance/optimizing-content-efficiency/http-caching

You cannot directly control what the browser chooses to cache but you can
use mod_expiry and friendly-reusable URLs (like XYZ tiles) to help in that
cause.  Repetitive WMS requests will be caught by the cache but it's much
harder to get a hit as it will change when the screen size, resolution, or
small shifts in locations differ.

To directly answer your questions:
1. No, you are not correct. The browser CAN cache those requests.
2. Yes, the browser will cache those images.

Cheers.

Re: [mapserver-users] mapserver 4.8.3 errorsing libgd 2.0.16 (or higher) from ....

[Dan Little]

I believe on RedHat-centric systems it's the "-devel" pacakges.  I don't
remember if it's "gd2-devel" or "libgd2-devel" but those would contain the
gd.h file.

That looks like a VERY OLD set of installed software. PHP 4.4.2 is
potentially even unsafe to be using on the server.

Re: [mapserver-users] mapserver 4.8.3 errorsing libgd 2.0.16 (or higher) from ....

[Dan Little]

Have you installed the headers for GD? And depending on the complexity of
your Mapfiles, it might be a good time to move to a newer version of
MapServer.  There have been a number of significant improvements since
4.8.3.

Re: [mapserver-users] TIGER data Mapfile update.

Hey Bob,

Is there any chance you can start a GitHub repo with an appropriate license
and maybe some screenshots for this? It's hard to use dropbox as a
collaboration platform...

Re: [mapserver-users] Fwd: Zoom to something and display in one shot from MapServer CGI.

[Dan Little]

You're likely better off with a simple script that computes the bounding
box and then uses mapserver to render the map.

E.G.: /cgi-bin/parcel-view.py?PIN=[xyz]

def getParcelBBOX(conn, pin):

Re: [mapserver-users] Oracle SYSDATE in EXPRESSION

[Dan Little]

Again, you could do that with the stored procedure or in SQL with a view.
And have a column that returns the logical style class. For example,

CREATE VIEW
SELECT
  CASE WHEN permit_date < SYSDATE - 365 * 5 THEN 'old_permit'
   ELSE 'active_permit' END as permit_class,
   ... other columns ...
FROM permits;


Then in the mapbook...

CLASS
 EXPRESSION "[permit_class] == 'old_permit'"
 STYLE
   [ style stuff ]
 END
END

Re: [mapserver-users] Oracle SYSDATE in EXPRESSION

[Dan Little]

You're probably better off with a view or querying against a stored
procedure. There are a few advantages:
1. With a view you can create multiple arbitrary views.
2. It keeps the syntax of the mapfile cleaner.
3. A view is easy to change to a materialized view in Oracle.  That has a
pile of performance benefits.
4. A stored procedure can be used to normalize the data better between
Oracle and mapserver.

Re: [mapserver-users] Oracle Layer: how to set context prior to fetching the data

[Dan Little]

The other option is to create yet-another stored procedure wrapper.  In the
Mapfile, you'd call the special wrapper stored procedure and it would
return the rows to map.

Re: [mapserver-users] Spatial access restriction based on secret in URL, WMS Getcapabilities

If you launder everything through a script (in any of your favorite

Re: [mapserver-users] Web Client

[Dan Little]

For something simpler, you may want to consider GeoMOOSE.

1. It has a very nice catalog that has been really refined over the years.
2. The Zoom-in/Zoom-out and other capabilities are built atop the
well-proven OpenLayers 2.X code base.
3. It is highly customizable with CSS but comes with a nice set of icons
from the start.  It also uses Dojo for its widget library and can be highly
customized with that toolset.
4. The services (such as search, etc.) are based on PHP but are also very
small, light weight, and easy to change.

GeoMOOSE has some other advantages:
- The install is not very large.
- It requires no more PHP dependencies than MapScript (the windows/MS4W
deploy is very easy)
- It can be configured with an XML file.
- We are constantly working on documentation and have a lot of it at our
website www.geomoose.org along with a handy demo at demo.geomoose.org

/me will now stop self promoting. :-)

  Hi,

 First of all I would like to say Hello to everybody as I am a newbie of
 both MapServer and the mailing list.  I need some suggestions about the web
 based client to send WMS and WFS requests to Map Server to display map and
 database records.

 I had a look at the internet and found some projects. But it takes
 unbelievable long time to read all documentations to see if it provides a
 few things I need. The basic functions I need are:

 - Possible to list layers
 - Solid zoom in/out functions
 - Design/icons and display functions customizable
 - Preferably written in PHP (not a must)

 I won't say no if there's one provides more functions :)

 So I wanted to ask which clients are good enough just like a daily chat
 with friends :) I hope I am not breaking any rules of the group at the
 first day.

 Any suggestions?

 Many thanks in advance
 Ceyhun

Re: [mapserver-users] Can the PROCESSING layer attribute be set dynamically through (PHP) MapScript?

[Dan Little]

You might want to reconsider how your script is built.  Instead of
loading up the Mapfile and tweaking small parameters with MapScript,
consider converting your mapfile to a template language.  This way you
can forumulate the mapfile, load it as a string, do the appropriate
substitutions, then use PHP to serve it as WxS.

This usually ends up being faster, easier to maintain, and more
flexible over the long term.

 Hi all,



 I’m drawing layers based on GRIB data files. Each file contains several
 bands (datasets). I can access these datasets by setting the PROCESSING
 attribute on the LAYER object. As in this example:



 #

 LAYER

   NAME current_grid

   TYPE POINT

   CONNECTIONTYPE uvraster

   DATA
 /var/www/mapserver/data/grib/routeguard/4nwwin99_2013110412.grb2#v and
 u-component of current

   PROCESSING BANDS=1,2

   PROCESSING UV_SPACING=20

   CLASS

 STYLE

   SYMBOL arrow

   ANGLE [uv_angle]

   SIZE [uv_length]

   COLOR 255 0 0

 END # style

   END # class



   PROJECTION

   #init=epsg:4326

   +proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs +pm=-360

   END

 END # layer

 



 This works fine. But I need to set the PROCESSING values dynamically
 through mapscript. If I add this code to my script (which works fine without
 these lines):



 

 $map = ms_newMapObj($_GET['MAP']);

 $current_layer = $map-getlayerbyname('current_grid');

 // both of these do not work

//$current_layer-set('processing', 'BANDS=1,2'));

 //$current_layer-setprocessing('BANDS=1,2'));

 $request = createRequest();

$result = $map-owsdispatch($request);

 



 I get an internal server error (500). It seems that setting any attribute
 via the layer-set() method causes this behavior. I’m migrating from MS 5.4,
 does the set method still work as expected?



 Thank you

Re: [mapserver-users] lighttpd, TNS:could not resolve...

[Dan Little]

I was starting to suspect MapServer is just no seeing the environment 
variables...

Try this... write a wrapper script mapserv.sh

#!/bin/bash

TNS_ADMIN=/home/gis/conf

/home/gis/bin/mapserv

Then update your script to point to mapserv.sh.

[mapserver-users] GeoMOOSE 2.2 Released!

[Dan Little]

Hello MapServer Users,

We here at the GeoMOOSE project are pretty excited for our latest release and 
believe it deserves some bragging on the lists.  We are actively looking for 
additional contributors (developers, documenters, designers) and would like to 
share our latest progress!

This latest version provides exciting new features that users have been 
requesting.  Some new features to GeoMOOSE 2.2 include:

* New website with more documentation and a redesigned gallery
* Implementation of Trac to submit bug and enhancement tickets
* New layer types such as Bing Maps, Google Maps, Yahoo Maps, 
OpenStreetMap tiles and ArcGIS Server Rest services
* A new demo application to highlight the additional layer types in a 
Web Mercator projection
* Enhancements to the selection/buffer services and ability to download 
selection results
* Bug fixes to the geocode and popup services
* Addition of a feature report service
* Addition of a query builder service
* Addition of a user extensions framework to add your own code to GM 
without modifying the core libraries, an example of this is a dynamic zoom 
service
* Addition of custom cursors and scale bars
* More catalog presentation optionsPlease visit the gallery 
http://www.geomoose.org/gallery to see what users have been using GeoMOOSE for 
or to submit your own application.  You can also visit the live demo from the 
main website link at the top of the page.
GeoMOOSE (www.geomoose.org) is an open source web application framework for 
displaying geographic data.  What makes GeoMOOSE unique is it provides an 
out-of-the-box solution that makes it easy for non-developers to create 
web-mapping applications with typical tools such as navigate, search, measure 
and print. Non-developers only need to be comfortable with configuration files. 
 GeoMOOSE has a number of strengths including modularity, configurability, and 
delivers a number of core functionalities in its packages.  The project has 
targeted local government business cases to distribute land records 
information, but many other users have used it for much more.  Since GeoMOOSE 
is open source project it built on other popular open source projects such as 
OpenLayers (www.openlayers.org) and MapServer (www.mapserver.org).  To get 
started with GeoMOOSE, simply go to the download page and install the software 
demo.


We are excited to see the inception of this project go from a an application 
developed by the City of St. Paul, MN to FGDC CAP grant to a robust open source 
software project used by hundreds of people across the world in the last 3 
years.  We hope you find the investment made by all the developers a resource 
to the GIS community.  We are excited to see this project grow and we envision 
continued growth as more and more users find it.  We welcome feedback on the 
GeoMOOSE project and hope you give the software a try.

Contact the project steering committee for more information:

Re: [mapserver-users] hyper-threading and performance

[Dan Little]

Hey Mark,

If you're looking to speed up GeoMOOSE (or any MapServer Installation) there 
are a few general rules to follow:

1) GM Specific - As of 2.0+ it's actually A LOT easier to have multiple layers 
in a single image.  The CPU capabilities doesn't help here, but the client has 
less images to download and will appear to be a bit faster.
2) MS General - INDEXES, TILING, INDEXES.  If you don't want to use shptree and 
the various shp* utils for indexing and tiling your dataset then you might want 
to try putting the data into PostGIS.  Especially datasets like road ways and 
parcels.  

Your aerials will generally better from more CPU capability.

 Yeah, I've heard the same thing.  If your system is cpu bound then I'd 
 bet the difference between enabled and disabled is minimal (regardless 
 if the difference is faster or slower).  20% either way is not very much.
 
 If your not cpu bound, I'd bet you see no difference at all.
 
 Of course, these are hugely big guesses.  And probably wrong.  I dont 
 have any numbers to share.  Sorry.

  Andy,
 
  To be more specific:
 
  I am using GeoMoose.  GeoMoose draws each layer separately so we do benefit
  by having a multi-core processor even if there is only one user.  We also 
  are
  using a WMS Service so air photos is for the most part a non issue.  If my
  understanding is correct hyper-threading has up to a 20 percent increase in
  speed.  However, the performance increase is highly application specific and
  in some cases performance may actually be lower with Hyper-Threading 
  enabled.

  Hey Mark,
 
  What sort of usage are we talking?  Web hosting?  Shapefiles and arials?
 I'm not sure if mapserver itself will use mult-threads, but if you
  have multiple requests comming into a website, apache/cgi/mapserver/etc
  will use multi process/threads/etc.
 
  Its tough to say the performance increase.  I'm host several maps on a
  dual-core box, and the cpu's sit around 2 percent.  And with lots of
  arial imagery you might hit disk io limit before you hit cpu limit.
  (However, I have had some mrsid files that were really cpu intensive to
  uncompress, they were cpu bound).  Are your cpu's even pegged?
 
  So, I guess, the answer is, it really depends on a lot of different
  variables.

More information about this error may be available in the server error log.
 
I checked the shapefile and map file for errors and couldn’t find any. And 
mapserver has been installed correctly and has been working well. The problem 
only arises when I add the extra layer. It works well with all the existing 
ones. 
The map file works on my PHP map display page but when I try it using WMS it 
does not work.  

I use MapServer 5.0.
  
Any help would be greatly appreciated.

Ian, 
 
I haven’t used tilemode, but my assumption is that the map
projection block is used to define what the output projection for your tile 
is
(like in the other MapServer modes).  
 
Try setting map projection to epsg:3785 or using the proj4 text:
 
+proj=merc

If tilemode requires a map extent, it should be expressed in
units of the output projection.

Hi everyone,

I've spent the better part of today scouring the internet for 
documentation and
help on the tile mode present in mapserver, but I couldn't find an answer to 
my
problem, so please forgive me if I'm missing some obvious documentation some
where...

I am attempting to show some GeoTIFFs (from here:

My research says they're in epsg:31984.

I'm trying to use MapServer's tile mode to display them on a Google Map 
API
instance, but can't seem to get any of the images to show up.

Also, why am I required to give a PROJECTION statement as a child to the 
MAP

is just going to reproject to spherical mercator?

My .map file is below.

Hi, 


I have set up a Mapserver which serves up aerial photography. 
 Works better than just great! 

Now, I'm trying to write some

allows me to write a script in a kind of XML, which then gets compiled to a

With this tool, I can set an image(JPEG) on my page 
from anywhere on the web, simply by using the correct URL.  However, I 
cannot understand how to create the URL to get a JPG file from the mapserver. 
 The troubleshooting data suggests that the problem is with an unescaped 
ampersand () ... is there a way to escape this escape madness?   


URL:

 Subject: [mapserver-users] attribute bindings for SYMBOL and FONT?
 
 The short story:
 
   Is it possible to bind a CLASS's SYMBOL object to an attribute (i.e store 
 the 
 symbol name as a attribute of a feature)?  And the LABEL objects FONT name?
 
 The Long Story:
 ---
 I've been working with the yet-to-be-released Feature Editor in Geomoose v2. 
 It 
 allows the user to digitize features (points, lines, and polygons) and assign 
 attributes, then stores them in PostGIS.
 
 I want to allow simple styling and don't want to have a map file the size of 
 War and Peace, so I thought I would use the attribute/item/column binding 
 abilities of Mapserver's CLASS and LABEL objects.
 
 To that end, one of the columns the feature table will be style name (or 
 maybe 
 feature class), which I'll use to join to a style table (with COLOR, WIDTH, 
 etc columns) to get the feature rendered in a simple style.
 
 After a quick review of Mapserver's doc, most of the most important objects 
 can 
 be bound to attributes, with two exceptions, SYMBOL 'name' and FONT 'name':
 
 CLASS
   STYLE
 ANGLE [angle]
 COLOR [color]  #R G B
 OUTLINECOLOR [olcolor] #R G B
 SIZE [size]
 WIDTH [width]  # v5.2
 
 SYMBOL 'name' # in SYMBOLSET
 
   END #STYLE
 
   TEXT ([label])
   LABEL
 ANGLE  [label_angle]
 COLOR [label_color]
 OUTLINECOLOR [label_olcolor]
 PRIORITY [label_priority]
 SIZE [label_size]
 
 FONT 'name' # in FONTSET
 
   END #LABEL
 END # CLASS
 
 How difficult would it be to have attribute binding for SYMBOL and FONT?  I 
 suppose I could use mapscript, but I'd rather not.
 
 Thanks!
 Brent Fraser

Hello List,
 
I want to be able to draw a circle dynamically using PHP MapScript. The
circle is defined by the coordinates of the centre and the radius in 
kilometers.
I realize that the circle is a polygon and I should probably calculate all
points. What is the best way to do it? 
 
I would really appreciate any help!

Re: [mapserver-users] Web interface

[Dan Little]

Like Bob said, there isn't any creation/management tools.  I've been running a 
general philiosophy that, at some points, users will need to hack mapfiles.  In 
the downloadable demo, we've been trying to give users enough exmaples to make 
it easy to learn and modify to their specific needs.  We also try to provide an 
example structure on how to make the management, of even large sites, sane.  
And that sanity can be acheived with basic tools instead of needing to 
convolute the whole process.

I have been considering writing some code that would:
a) Provide online editing services with a database short of needing PostGIS, 
like oh, SpatialLite.  Something we could distribute more easily with the 
project.
b) Work with Bob (and the team he has) to generalize some of the tools they 
have developed, get them working with Spatial/SQLite and try to make them 
publically available.
c) Porting the code to Ruby and/or Python.  Ruby is my new favorite language 
but Python is more practical for a ton of reasons.  The PHP works and is 
fairly accessible to novice users but I find the language ugly and more 
difficult to maintain than the others.  Of course, PHP seems to be the defacto 
language of MS4W ... which is why we've stayed married to it.  I'm probably 
more likely to develop more user tools if it's in a language other than PHP.

Of course, any assistance in either man-hours or funding is greatly appreciated 
towards any of these ends.

 All,
 
 I can chime in here on something related.  While GeoMoose doesn't (currently) 
 have any Mapfile tools, I'm currently in the middle of a project that has 
 built 
 out some autoconfigure items for MapServer.  The project is fairly specific 
 in 
 it's business tasks so the configure aspects are in their infancy, but it's 
 got 
 a real nice framework around it that will be very extensible.  We're using 
 GeoMoose, so it also (will) autoconfigure the GeoMoose interface to some 
 degree, 
 and hopefully future versions will be able to more fully control things.
 
 BTW, the initial ease of setup of GeoMoose has enabled this type of control 
 structure very nicely.  Some of the future items to figure out, is how to 
 best 
 accommodate those folks that also want to get into the MAPFILES and tweak 
 them 
 manually while still maintaining the autoConfigure aspects.
 
 Look for something in the next 30-60 days.

Re: [mapserver-users] Dynamically update layers without service interruption

[Dan Little]

Yes, it's a matter of how you do your data management.

Generally, if you're using MapServer in CGI mode you can update the data, or 
the mapfile, and the next time a request comes in, it will see the updated 
version of your image.

 Is it possible to dynamically add and/or update layer definitions that
 also might involve updates to the underlying data without *any*
 service interruption? I'm primarily interested in this use case when
 using raster layers.
 
 I have indications that service interruptions can happen but cannot
 verify yet. I found
 http://www.mapserver.org/development/rfc/ms-rfc-44.html#rfc44
 describing the feature of dynamic updates (I assume?) but no mention
 about if service interruption can be expected and/or how to avoid it.

Jay,

 

you must use FILTERITEM only for simple FILTER expressions
(string comparison only)

for example: 

FILTER 2005 -fieldvalue
FILTERITEM year -fieldname

 

For Logical FILTER expressions you do not define
FILTERITEM. In this case you must place the FILTER between parentheses,
and fieldnames between brackets 

 

for example:

FILTER ([field1]4000 AND
[field2]==Museum) --observe quotes on both sides on
text fields

 

See http://mapserver.org/mapfile/expressions.html#expressions for
detail on how to build logical expressions

 Good question. I think you would have to do that on a Windows box because the

You have a few options based on what you know about ahead of time:

1) If you know the stacking order ahead of time you can create separate layers

2) If you don't know the stacking order ahead of time, you can try using 
patterned fills instead of opaque fills.

Re: [mapserver-users] SUA convert

[Dan Little]

Shapefiles tend to be faster for processing than KML, however, KML gives you 
the benefit (?) of being able to present your data in Google Earth.  If you're 
just looking to display the data in Mapserver then I would definitely consider 
writing shapefiles.

MapScript (Python, Perl, PHP, whatever) has the ability to write shapefiles 
pretty easily and in Python you can write the DBF file using dbfpy, in perl you 
can use DBD::Xbase.

  Hello everyone,
  
  I am currently using a wrapper around mapserv which receives the URL

 with 
 the passed in parameters). After the map file is built, mapserv is called (as 
 a 
 shell script), and the map gets sent to the user. Currently this wrapper is 
 written in perl - so it's not terribly fast as a cgi process.
  
  While this approach works, it is terribly inefficient. I would like to 
  use 
 mapserv as a fcgi process (or something faster than plain cgi). My question 
 is - 
 how can I /should I build a wrapper around mapserv that can customize the 
 MAP 
 file on the fly and run as a fcgi process?
  
  Any ideas on where I should start? An example of such a wrapper?
  
  Also, I suspect I can send parameters to mapserver and use some sort of 
 variables in the map file to set up my filters - but I haven't seen an 
 example. 
 Can someone point me to such a documentation?

  Have you seen mapscript?  You can use mapserver directly from perl.  And 
 perl can do fast-cgi.  Here is a little, ad-hoc, non-tested, perl fcgi:
  
  
  #!/usr/bin/perl
  
  use strict;
  use mapscript;
  use FCGI;
  
  
  my $request = FCGI::Request( );
  while($request-Accept() = 0)
  {
  my($req, $x, $at, $xmap, $xpin, $sid, $y, $q);
  
  $req = new mapscript::OWSRequest();
  $req-loadParams();
  
  $xmap = $req-getValueByName('map');
  $xpin = $req-getValueByName('pin');
  
  my $map = new mapscript::mapObj( /maps/$xmap.map );
  if (! $map)
  {
  #print STDERR - Error loading map: $xmap.map\n;
  print(Content-type: text/text\r\n\r\n);
  print cant load $xmap.map;
  $request-Finish();
  next;
  }
  
  mapscript::msIO_installStdoutToBuffer();
  
  $x = $map-OWSDispatch( $req );
  if ($x)
  {
  print STDERR OWSDispatch: $x\n;
  my $errObj = new mapscript::errorObj();
  while ($errObj) {
  print STDERR ERROR: 
 $errObj-{code}:$errObj-{message}:$errObj-{routine} \n;
  $errObj = $errObj-next();
  }
  }
  
  my $content_type = 
  mapscript::msIO_stripStdoutBufferContentType();
  
  $x = mapscript::msIO_getStdoutBufferBytes();
  
  
  print(Content-type: $content_type\r\n\r\n);
  if (mapscript::msGetVersionInt() = 50500)
  {
  print $$x;
  } else {
  print $x;
  }
  
  mapscript::msIO_resetHandlers();
  $request-Finish();
  }
  
  
  
  I'd recommend using mapserver 5.6.0.

   Thank you,
  
   I will look into it. I guess through mapscript I can redefine the

  You can load a map into memory (I assume you were already doing that). You 
 said ..perl.. receives the URL parameters ...and... builds the map file.
  
  
  I assume your perl does: use mapscript?
  
  and at some point: my $map = new mapscript::mapObj( /maps/$xmap.map );
  
  You kind of imbed mapserver into your perl script, and can call its 
  functions 
 and what not.  After you load the map you can do things to it, in memory.
  
  In my example above, I'm using the WMS features ($map-OWSDispatch), but 
  you 
 can also generate an image:
  
  my $img = $map-draw();
  $img-save('x.jpg', $mapscript::MS_JPG);

Re: [mapserver-users] Starting with TIGER Line Data and MapServer

[Dan Little]

A few questions for you.

Regarding #1
Were all of your shapes in the same projection as the Itasca demo? If not, 
their coordinates may have been far outside of the extents of the map.

Regarding #2
Do you have 300 shapefiles, meaning you have 300 layers you wish to display?  
If so, you might want to take a look at an alternate solution than the Itasca 
demo.  For example (toots own horn) GeoMOOSE is designed to allow multiple 
mapfiles to be used within a single application.   It makes the management of 
the large number of layers much more palatable.  We also have a number of users 
that are at the same level of layer management as you are and could give more 
suggestions on how to best manage that data for use in a Web GIS.

 Hi,
 
 We are working on displaying the TIGER Data using MapServer.
 This is our first time with MapServer, and we would appreciate your
 help in the following areas:
 1. We could run the Itasca Demo Application. However, we could not
 integrate our shapefiles with the sample Mapfile. We have read the
 Mapfile documentation at the MapServer site. Any pointers on creating
 Mapfile?
 
 2. We have chosen a single state for our initial demo. However, the
 number of shapefiles is almost 300. How should we incorporate all
 these in the Mapfile?
 
 
 Any suggestions are welcome.

Re: [mapserver-users] Quantize and 8bit/1bit PNG problem

[Dan Little]

You could use a Python/PHP mapscript wrapper that tests to see the number of 
colors in the PNG before returning it to the client.  In such a case you could 
manipulate the PNG using GD/PAL/Cairo/Graphics-Library-of-the-Month.

 Pål,
 
 One bit PNGs are a perfectly valid response.   I would suggest
 two approaches.
 
 1) File a ticket with Microsoft on Bing Maps, and hopefully they will
 roll a fix into their operational build within a couple days.  (ha ha)
 
 2) Manually produce a nice empty tile that works with Bing Maps some
 other way, and write a script to replace the 1bit PNG file (which should
 presumably have a fixed size) with the bing-safe ones.
 
 Perhaps not the sort of answer you were hoping for, but you did
 implore us for comment even when none of us thought we had anything

I'm also assuming that your directory definition was not copied, pasted and

Subject: [mapserver-users] access problems from cgi-bin on Mac OS X 10.4.11 / 
MAMP


So I'm a first time MapServer user and have been trying to navigate the 
installation process. I think I almost have it, but I am having some last 
problems. When I access my executable mapserv file from the command line, I 
get this: 


This script can only be used to decode form results and should be initiated as 
a CGI process via a httpd server. 

All sounds good, right? Well, I am using MAMP to host an Apache2.0 server. 
The httpd.conf file has the following in it:

Alias /cgi-bin/ [rootfile]/cgi-bin/ 

Directory [rootfile]/cgi-bin/\
 
AllowOverride None
 
Options ExecCGI FollowSymLinks Indexes
 
Order allow,deny
 
Allow from all

/Directory\ 

AddHandler cgi-script .cgi .py 

I know that first line should probably be ScriptAlias, but I kept getting a 
Permission Denied message and read in a forum that this was a solution 
somebody had come up with, and indeed it worked for me as well. 


Anyways, the problem is that in this cgi-bin I have my mapserv  executable 
(though one of the things I'm thinking is that maybe I need to add something 
else to AddHandler to make it think that this file is executable?). But when 
I got to //localhost/cgi-bin/mapserv it tries to download the file as 
Untyped Binary Data and it doesn't execute anthing.  

In case its of any help the ls -l for my cgi-bin gives the following 
information:
-rwxr-xr-x   1 Rebecca  Rebecca   51244 Jul  9 07:52 mapserv 

Do I not have this installed correctly? Or is my server just not realizing 
that this is executable. I would be thrilled if I could just get to the point 
where //localhost/cgi-bin/mapserv just brought up a No query information to 
decode message, since I think I can handle it from there. 


Thank you very much,

Rebecca

Re: [mapserver-users] best practice: map data structure

[Dan Little]

The most includes I've used in a single file is around 100.  50 or so layers 
each with a separate label and shape layer.  It worked pretty flawlessly.

There are two solutions to possibly keep in mind:
1 - Shameless Plug) Use an application setup like GeoMOOSE.  We have the 
application serve many layers in diverse mapfiles to try and simplify the 
management of mapfiles.  Version 2.0 is even better about this because you can 
use hybrids of different types of mapfiles to break down the problem however is 
best for display and performance.

2 - A bit more technical solution) Use a compiler.  Write a small file format 
that has a list of the mapfiles you wish to combine together, then write a perl 
script that combines the files together from the list.  This essentially 
performs the mapserver includes ahead of time. :-)  I've used this on various 
projects -- I'm even willing to share source-code ideas if you backchannel me.

 Hi Dan,
 
 thanks for your response. Using includes for the layers is a nice idea, and 
 it 
 keeps the layer data and configuration together. And you'd get a good 
 overview 
 over all avail. layers on your server just by looking at the existing. 
 directories. Even postgis layers would have a directory since the layers 
 mapfile would be stored there. And you could have several stylesheet layer 
 map files in the directory ...
 And in an application directory you could include all the layers necessary 
 for 
 the application in a master mapfile.
 
 Do you have experience in using lots of includes within a mapfile? I remember 
 using includes for about 30 layers in an php application (pmapper) once 
 (v4.10 
 on ubuntu 7.10) and I run into problems. namely there where too many open 
 files opened by apache and the mapserver process. It seemed, that the 
 includes 
 weren't closed, and each time the map was redrawn, the includes where opened 
 again and so the file system limit of max. open files was reached quite soon.

   /symbols/ - symbol.map
   /templates/ - template files

Actually, I don't think it's a great example, but it shows you how to create a

showing the direction the animals moved, within a user specified time frame.

I'm open to any feedback on this - it's a modification of one I modified from

I should say, note the use of debug. the error messages are invaluable when it

It is very dependent on your needs.  For example, if you have departments 
responsible for various layers you may want to divide the structure by that, if 
there is only one administrator then that isn't necessary.

Typically, if there is only one administrator I tend to do something like 
this...

[root]/ -- make this whatever you want and that makes sense from a permissions 
and storage stand point for your new server.

for a simple shapefile layer...
[root]/layer_a/layer_a.map
[root]/layer_a/layer_a.[shp|dbf|shx]

for a tree'd shapfile
[root]/layer_b/layer_b.map
[root]/layer_b/layer_b.[shp|dbf|shx]
[root]/layer_b/data/[... quad tree goes here ...]

for a raster...
[root]/layer_c/layer_c.map
[root]/layer_c/raster/[... raster data ...]

Then you can use mapserver includes to include the proper mapfile fragments 
into an applications various mapfiles.

 I will be using a linux server, so the structure will reflect the unix 
 filesystem hierarchy to a certain degree.
 
 A good starting point seems to be /usr/local/ to me.
 
 /usr/local/mapdata/ for storing raster and vector files
 /usr/local/mapfiles/ for mapfiles and other config files
 
 You would have /usr/local/mapdata/CLIENTDIR/vector and  
 /usr/local/mapdata/CLIENTDIR/raster for client specific map data
 similar to
 /usr/local/mapdata/PROJECTDIR/... for project data
 
 and /usr/local/mapdata/share/vector  /usr/local/mapdata/share/raster for 
 shared map data (srtm topo maps e.g.)
 
 A good structure for mapfiles  co would be:
 /mapfile.map
 /fonts/ - font config and font files (ttf)
 /icons/ - icon files (png, ...)
 /symbols/ - symbol.map
 /templates/ - template files
 
 This structure could be mapped to 
 /usr/local/mapfiles/share/...
 or
 /usr/local/mapfiles/CLIENTDIR/...
 
 I would really appreciate any comments and shared experience on this ...

Hi,
 
We are using Mapserver to produce tiles for a web application, using Tilecache 
as the caching mechanism. 
 
When we were building the system, we figured out that tiles requested does not 
fit well side by side (the roads of one tile does not fit the prolongation of 
the same road in the next tile). To eliminate this issue, we had to issue an 
extra 10 pixels (around the whole tile) request to Mapserver and then cut them. 
 
Then another problem arose: we could not make this with the labels because they 
appeared cut in one tile and there was no prolongation of it on the next tile. 
The solution was to divide it into different layers: one for the roads with the 
10 pixels buffer and another for the labels without buffer. This has the impact 
of duplicating the total number of images.
 
Anyone known an alternate solution for this problem?
 
Isn't Mapserver capable of serving images that fit well side by side?
 
Thanks in advance!

Re: [mapserver-users] Mapserver images doesn' t fit well on a tiling scheme‏

[Dan Little]

I think you're a bit wrong there.  If you build the Cache using tilecache, when 
you use the metaTiles it will take a larger sample than the image being 
generated, for example if you have a 3x3 meta tile grid, the center tile of 
the nine-tile grid will be used.  I had the exact same problem you are 
describing, but then setup the tilecache generator to use metatiles and things 
started to work beautifully -- including labels.

With metaTile I can issue a pre-defined number of tiles that fit well. But this 
is per-request (if I'm right). For instance, if I make two consecutive requests 
of 4 tiles each from consecutive map zones, I get two sets of tiles that does 
not fit with each other (the first 4 do not fit side by side with the second 4).
 
The problem with that approach is that tiles from the same request fit well, 
but in order to construct a map like VE or Google Maps I need that tiles from 
different requests to always fit well.
 
Please tell me If I am wrong.

Re: [mapserver-users] Mapserver images doesn' t fit well on a tiling scheme‏

[Dan Little]

There are two steps to a tilecache...
Step 1: Seeding it.
Step 2: Querying from it.

Metatile usefulness is best seen while seeding the tile cache.  If you look at 
the attached graphic (a rough estimation of a 3x3 meta-tile setup) then you'll 
see as the tilecache seed iterates through the map, it oversamples the map 
and uses the center image to represent the tile (A).  When moving onto the 
next tile (B), it performs the same over-sampling.  Since the map is then 
never at the edge of the generation you do not see errors with off-map lines 
and labelling at the edges.

Now, there two ways to query the tilecache:
1) As a WMS service.  IMO, this is slow you can do as you wish but I've always 
thought this to be quite a bit slower than taking the oppurunity to fully seed 
a tilecache.  In this scenario if you have a cache hit there is no additional 
generation costs.  If you have a cache miss the generation cost is greater, 
but mapserver, PIL, etc., are very efficient at generating images.  The actual 
cost of generating a 256x256 image and the cost of geneerating a 768x768 image 
is not terribly significant.  Plus, once it has been done for a tile, it never 
needs to be done again.

2) As a tilecache, this is where you just serve up the directory as a 
TileCache.  This is a lot faster but assumes you have fully seeded your cache.  
In this scenario you have no additional generation costs, all of that work has 
been done up front.

 I'm not sure if I got it right... When I request a 3x3 meta tile grid, 
tilecache only caches the center image? What if I request the image on the 
right of it and again another image to the right? Tilecache will issue new and 
overlapped requests to Mapserver? Or for the second request it will reuse a 
tile from the previous 3x3 request?

 To summarize, here is the way to *completely* avoid truncated labels
 and edge artifacts:
 
 * use a 10 pixel metabuffer in your tilecache config (the number of
 metatiles is irrelevant, but as Chris points out, there'll be more
 labels included if you use a 3x3 (or more) metatiling scheme than a
 1x1 one :
 
 metaTile=true
 metaSize=3,3
 metaBuffer=10
 
 * set a 10 pixel edge buffer in mapserver (so no labels are rendered
 in the 10 pixels on the edges of the image) :
 WEB
 METADATA
 labelcache_map_edge_buffer -10
 END
 END
 
 * use PARTIALS FALSE in all your label blocks

Re: [mapserver-users] dynamically added shapes and their values

[Dan Little]

Totally spit balling...

What about writing your layer to a temp. file that's KML/GML.

The file size is small, it carries the attributes you want, and it's easy to  
write the file using anything that writes text files (presumable C# can write 
text files ... but I know Microsoft misses little details from time to time).

Then write yourself a little mapfile you can open... maybe following this as a 
guide...
http://mapserver.org/input/vector/gml.html
-or-
http://mapserver.org/input/vector/kml.html

And just change CONNECTION using Mapscript to whatever the location of your 
newly created KML/GML file happens to be, then proceed with the processing.

Re: [mapserver-users] PHP Mapscript question

[Dan Little]

Rafeal,

I think you'll need to clarify a little bit more.  Mapscript is a library you 
use inside of a PHP script.  If you're trying to access data on another server 
then you'll need to be more specific about what that data might be.  If you're 
trying to retrieve an image from another server then you might want to look 
into php curl.

Re: [mapserver-users] newbie: Error in first atttempt to use postgis with mapserver?

[Dan Little]

Newer versions of Postgres do not automatically create an OID column, as it was 
a limited 32-bit construct.

Try add using unique XXX where XXX is the column name of the primary key (or 
at least a unique key).  If you've uploaded the layer from a shapefile using 
ogr2ogr you can use the column ogc_fid

Re: [mapserver-users] Mapserver.org sample ...

[Dan Little]

Bob  Chris,

OpenLayers and GeoMOOSE are entirely non-competitive projects.  The OL is a 
library on which to build mapping interfaces such as GeoMOOSE.  Which is why 
we're using it for GeoMOOSE 2... it gets rid of a lot of the tedium of 
maintaining code for the more basic aspects of the application (like Zooming, 
Drawing, etc.). 

The real advantage to GeoMOOSE is the service model, and the litany of services 
we try to make easy to configure for users.  Out of the box GeoMOOSE is high 
customizable but also highly useful.  The goal is to provide an interface to 
mapserver that works WITHOUT any coding.  I want people to know ZERO 
javascript, php, or python, and still be able to use the web-mapping client.

 Chris,
 
 The biggest piece I see GeoMoose contributing to, is the CGI calling methods. 
  
 GeoMoose makes extensive use of the ImageMap building and Query Mechanisms 
 available with MapServer, not just the image rendering.  Although the 
 stacking 
 of the images inside of the GeoMoose interface is and has been a novel way of 
 presenting the MapServer contructs (IMO).  OpenLayers does this as well to 
 some 
 degree, but I believe the GeoMoose interface provides a greater degree of end 
 user control.
 
 I'm interested in promoting more than just MapServer image rendering.  Using 
 Mapserver's CGI capabilities with a Client LIB is pretty much the way I've 
 used 
 MapServer since starting up with it over ten years ago.  The imagemap 
 (templating) and Query capabilities are just as important as the image 
 rendering.  The teaching reference below, was aimed squarely at the idea of 
 using MapServer via it's CGI calling structure, which I've always thought 
 should 
 be demo-ified in some location.  But since MapServer (and it's community) 
 hasn't 
 in the past had any particular interest in ratifying a client for use, I 
 never 
 pursued the idea.  But now, with that nice OpenLayers window on the MapServer 
 page, the sky's the limit so to speak, as far as setting up demos and 
 including 
 them in the MapServer site, or at least it seems like it should be.

 Absolutely. The demo on the MapServer site is using a layer that is
 generally not needed in any application -- at least not until you're
 looking for something that can be deployed without a MapServer 'server'
 in the mix.

 The dem on the MapServer main site seems pretty fast to me. Much faster
 than any non-cached demo I've seen. Are you saying that GeoMoose has
 tuned MapServer t such an extent that it is faster to render images than
 it is to serve pre-rendered tiles that demonstrate MapServer's rendering
 skills?
 
 * Handles many layers with ease.  The limit is the client hardware,
   and the control is given to the user as to how many to display.
 
 This is a GeoMoose benefit over other client software, but I don't see
 how it makes a better demo of MapServer's rendering capabilities.  
 
 * The publishing of the data can be distributed, down to the layer
   level, including the contents of the popups.  Each layer can be
   managed separately without consequence to the rest of the
   interface, if it breaks, only that layer is not available.
 
 This is a GeoMoose benefit over other client software, but I don't see
 how it makes a better demo of MapServer's rendering capabilities.  
 
 * More interface user Control, layer fading, on/off, stacking order,
   popup on/off.
 
 This is a GeoMoose benefit over other client software, but I don't see
 how it makes a better demo of MapServer's rendering capabilities.

   than you think.
 
 This is a GeoMoose benefit over other client software, but I don't see

   functionality for images, imagemaps, and querying.
 
 I don't knwo what you mean by this, so I can't comment on it.

Re: [mapserver-users] how MapServer manage the hyperlinks in the shapefile data table

[Dan Little]

Yes there is.  Look into the query and template functions in MapServer.

In the shapefile you should try to store a minimal representation of the 
hyperlink.  Like a ID or a relative URL.  That way if the look up system, or 
server, changes you do not need to do a complete update of your shapefile.

So, for example, say you had a column called OBJECTID that contained a unique 
identifier for the feature that is used in other systems.

In a template file you can do the following:
 a href=http://my.other.server/the/path/to/script.cgi?object_id=[OBJECTID]; 
target=_blankView in The Other System/a

 However, I wonder if Intel Atom is adequate to run MapServer. The MapServer

 be run on either ms4w on Windows XP, or directly on Linux. The layers are 
 stored 
 on postGIS (there are fifteen layers or so), and there is also a 476 
 megabytes

 Will Intel Atom be adequate for the purpose? Will 2GB of memory help? Has 
 anyone 
 ever done such thing before?
 
 Many thanks,

Did you make sure all the paths were properly setup?  I think you need to set 
an env variable to point to where the DLL's are located.

Also, Mapserver tends not to run really well from the commandline.  You'd need 
to set all of the environmental variables to account for the QUERY_STRING, etc.

In my experience it's easier to do a buffer on the line features first

Re: [mapserver-users] Showing pop up for a line

[Dan Little]

You may also want to use mapserver to render the lines as a raster layer 
instead of vector.

Re: [mapserver-users] map mode for ajax calls

[Dan Little]

You can actually call the legend and individual layer images.

For the legends, mode=legend will help you out.  For the layer images, you 
could iterate through the layer name list to generate each individual image.

 Hi all,
 
 I've been playing using ajax calls to the ms executable.
 I'm using map mode and piping to a file, and returning this file ref to
 update the image div, and it works fast and fine.
 
 I would also like to update the legend, layer images, and it seems that
 these are only produced in browse mode.
 
 Outside of parsing the map file produced to extract the above image names
 when one pipes the cgi, is there another, possibly simpler way? way?

Re: [mapserver-users] TEMP FOLDER

[Dan Little]

Hi Bernard,

I've cross posted this onto the geomoose user's list.
1) Temp folder files (in MS4W) can over-write themsevles, I haven't seen a lot 
of problems with this personally, if there's something that causing you 
specific heart-ache then you may have to specify.

2) Changing the draw polygon icon in geomoose is pretty easy.
a) Have an image available somewhere, I'm going to use 
/images/draw_poly_icon.png for my example.
b) Open the mapbook, go to the service tag that defines the draw polygon 
service.
c) Inside of the service ... tag add an icon attribute. Ex: service 
title=Draw Polygon icon=/images/draw_poly_icon.png
d) You may also want to add a different Icon for when the tool is selected, 
repeat the process above but instead of using icon as the attribute name use 
highlight

3) Depends on your level of previous database knowledge.  On the whole, there 
is a wealth of documentation on Postgresql.org and on the PostGIS website.  
There are also any number of books that are quite good, reasonably priced, and 
widely available.  If you already have a strong back ground in database use, 
then the docs on the website usually provide analogs to Oracle or MySQL 
experience which can be enough for some people.

Re: [mapserver-users] nfs drive

[Dan Little]

You have to have the drive mounted for whatever user that is, not just as your 
self.

You'll have to excuse me if I cannot give you specific enough details, I'm 
generally a Unix/Linux guy and tend to need to work with Windows' face-to-face 
to figure stuff out.

If you'd like a PHP approach to this problem you can check out the GeoMOOSE

 I'm working on the same thing right now.  The first option is to
 generate a high resolution raster image from mapserver and then user
 reportlab to put that into a .pdf.  The problem with this is the file
 size of the resulting .pdf is large, and the vectors still don't look as
 good as they could.
 
 What I've been working on now is using reportlab and svglib.  I create a
 high resolution .jpg of just the raster layers from mapserver, and then
 I create an .svg file of the vector layers.  I use svglib to convert the
 .svg file into a reportlab graphics object, and draw that on top of the
 raster into a .pdf document.  The file size is still large, but the
 vectors look much better.  The problem I'm having now is that not all of
 mapservers labeling options are available to svg output (namely, you
 can't wrap labels).

Re: [mapserver-users] transparent pixmaps in python mapscripts

[Dan Little]

It would be three step process.

1) Generate the image.
2) Perform the clipping.
3) Over lay the new clipped image onto the Aerial.

It would require two Mapscript calls to generate images (one for the overlay 
and one for the aerial) but it would let the solution work.  If you need any 
code I've used this method for a couple of applications' printing capabilities.

 You could render the map with a known background color, and then use PIL
 to create a transparent GIF from the image.
 
 If you can use white as the bg color then you can convert the image to a
 2 color bitmap in memory, and then use it as a mask to perform the
 transparency composition.

  TRANSPARENCY ALPHA works only between layers drawn using map.draw() in
 
  a
  single pass. If you call layer.draw() for each layer in a loop in your
