Hello


In the map file is this statement

DATA "GEOM FROM TEST_TABLE using unique objid_parent SRID 25832"

I get this message from mapserver in log file

Error: ORA-00907: missing right parentesis

. Query statement: SELECT SDO_AGGR_MBR(GEOM) AS GEOM from (SELECTGEOM

This have to be changed SELECTGEOM to select geom

Can I do something in the map file or is it a bug?

Re: [MapServer-users] I want to change Map

[Sven Schroeter via MapServer-users]

Hi,

Tile-based maps are provided in a predefined tileset. In the case of 
Google or OSM, for example, this is usually in EPSG 3857 and is defined 
in a grid with corresponding resolutions for the different zoom levels 
(always based on an extent): 
https://mapserver.org/mapcache/config.html#preconfigured-grids

A WMS is usually used as the data source.
Of course, you can also do this for self-defined tilesets with other 
resolutions and extents, as in the case of the Korean institute.
With MS4W and the Mapcache software it contains, you can define and 
create such a tileset yourself.


Greetings from Germany
Sven

Hello everyone.!
Good morning.

I'm Choi and I'm Korean.
I'm trying to load and manage a map.

1. I found mapwingis for C#

2. I found video for sample
https://www.youtube.com/watch?v=mBu9XgrfZfM
    In this video, he gets map images with SAS.planet program and 
supplies maps with ms4w.

    After, he loaded the maps in C# project with axmap.

3. I did the sample and it works well.

4. It will take about 200 days to get 20 level's maps with SAS.planet 
program for some area)


5. So, I got new maps about 4TB from https://www.ngii.go.kr/ is 
Korea's National Geographic Information Institute


6. But, I failed to load the new map in sample c# project
    // Source code used in video C# project
    providers.Add(providerid, "map", "http://127.0.0.1/map/z{zoom}/ 
*{y}/{x}*.png", 
tkTileProjection.SphericalMercator, 0, 13);


    // Modified Source code
    providers.Add(providerid, "map", "http://127.0.0.1/map1/z{zoom}/ 
*{x}/{y}*.png", 
tkTileProjection.SphericalMercator, 0, 13);



7. After I found some differences.

    - Sample's map is Google map based EPSG:4326 and file's array is 
{zoom}{y}{x} and image's size 256*256 pixels


    - But my new maps are based EPSG:5179 and files array is 
{zoom}[x]{y} and image's size

512*512 pixels

If someone knows the way to load my new maps with ms4w
Please, let me know.

Thank you!

Best regards
Choi.

When fn was empty, the image was sent to stdout. In SWIG-Mapscript,
this function has been replaced by ImageObj->save(fn), but fn cannot

Re: [MapServer-users] mapserver 5 installation

Hi Valeri,
I have created a document for the installation under the IIS, where the 
map server runs cleanly via the FastCGI module.
In addition, the map server is not addressed as mapserv.exe, but as an

My doku is in german, which is hopefully no obstacle;-)

Re: [MapServer-users] Tutorials for creating time dimension images and good web frontends for dynamically changing map projects?

[Sven Schroeter]

here are some quick ideas which tools could be interesting in this context:

If you want to start with python (or php) then I would think about using 
mapserver based on mapscript.

https://mapserver.org/mapscript/index.html
You can use ogr2ogr to easily create shapefiles.
For meteorological analysis the time parameter for WMS services is useful.
For leaflet there is a plugin: 
https://github.com/socib/Leaflet.TimeDimension


Happy mapserving

Am 14.10.2022 um 08:39 schrieb Stefan Gofferje:

Good morning all!

After the relative ease of my first mapserver project, I'm now 
motivated and keen on getting another project running.


Since about a year (plus minnus), I'm every day checking for Sentinel 
I and II data covering the area where I live. If there is anything, I 
download the data and run some scripts which do automatic processing 
and generating of composites, like SAR VV/VH or NDVI, NDCI, etc.

The ready images are then posted to a Telegram channel.

At the moment, there's still a number of manual steps (search data, 
decide what to download, trigger download, trigger processing and 
trigger Telegram push) and the existing scripts are Bash scripts 
calling GDAL tools.


My first step now is to learn Python and move everything from Bash to 
Python and automate it, ideally so far that the whole process can run 
in a Docker container as a cron job.


Then I was thinking, instead of pushing images to Telegram, I could 
use mapserver to serve the images to some web frontend. The map files 
are very easily created programmatically, so that should be easy. I'm 
missing a few things for that, though:
While going through mapserver's docs, I noticed that it can handle 
time dimensions for imagery. That sounds like something worth 
exploring. The docs describe the use of a shape file but 
unfortunately, I have no clue how to to *create* that programmatically.


Regarding the frontend, I could just put up a single page leaflet app. 
That would be easy enough. But I'm wondering if there's already some 
cool solutions out there.


So, If anybody has a link or pointer for me on the programmatic 
creation of shape files for time-indexed imagery and/or interesting 
web frontend projects, I would be very grateful!

So, basically, I 'find' all pngs/pgws, move them from the subfolders

shapefile which I use as data source? Let's try that.

Hi all,

Life (and COVID) hit, so I never got anywhere with updating my weather

Currently I have another project - due to the geopolitical situation:
I'm working on a mobile system to provide emergency/off-grid 
"tactical" communication and data. It's centered on a Raspberry Pi and 
includes things like Meshtastic and others. One of the things I would 
like to add is a WMS/WFS server to provide map data via local Wifi AP 
to connected devices.


Topographical (and other) maps of whole Finland are available under 
CC4 from the Finnish Land Survey through the KAPSI non-profit. The 
maps are in 12kx12k PNGs in a folder structure by UTM grid. See here: 
http://kartat.kapsi.fi/files/peruskarttarasteri_jhs180/taustavari_korkeuskayrilla/1m/etrs89/png/ 


The data can by rsync'd down.
I'm not clear how I would configure mapserver for that. Do I have to 
create one map with extent and such for each PNG tile or can I point 
mapserver to the root directory  of the data and tell it to go through 
it recursively and get the data from the PGW sidecar files?

 When I use Mapserver 7.6.4 in the same setup, the following lines appear:

-- /usr/include/php/20200930/main

-- Found PHP-Version 8.0.21 (using /usr/bin/php-config)

In Mapserver 8 these are missing and accordingly the output in 
mapscripts is:


--* Mapscripts

--* Python: disabled

--* PHPNG: disabled

That means PHP is not activated. In comparison the output with Mapserver 
7.6.4:


--* Mapscripts

--* Python: disabled

--* PHP: ENABLED

--* PHPNG: disabled

It is the same server with the same installation components. 
Accordingly, in a make and make under Version 8 install PHP Mapscript is 
not installed.


php - v generates the following

Unable to load dynamic library 'php_mapscript.so' (tried: 
/usr/lib/php/20200930/php_mapscript.so

Hello MapServer community!

I'm thrilled to announce that MS4W 5.0 has arrived for Windows users, 
with its first beta.  Get it at: 
https://ms4w.com/release/experimental/ms4w_5.0.0_beta1.zip


A ton of effort has been happening for months, almost a year, for this 
release (there have been 13+ alpha builds already).  The plan is to 
release the final MS4W 5.0 in January, along with the MapServer 8.0 
release then; but this first public beta allows power users and admins 
to begin adapting their environments.


As always feedback is encouraged through the MS4W issue tracker: 
https://ms4w.com/trac


A temporary link to the new documentation is: 
https://ms4w.com/README_INSTALL_MS4W_5.html (but please always use the 
local README in your download).


Here are some of the highlights:

- PHP 8.1 MapScript (very fast wow!)
- Python 3.10.1 MapScript (added quickmap.py and other test files, 
similar to the usual PHP files)
- ms4w.conf & other security requirements (see 
https://ms4w.com/README_INSTALL_MS4W_5.html#securing-your-ms4w-installation 
)


Your test workflow might be:

- open command prompt
- cd ms4w
- setenv.bat
# download PROJ grids locally
- proj-install-grids.bat (install grid files into 
/ms4w/share/proj/grids/  see 
https://ms4w.com/README_INSTALL_MS4W_5.html#proj-networking )

# test PHP MapScript (PHP 8.1 is very fast wow!)
- php -dextension=C:/ms4w/Apache/php/ext/php_mapscript.dll -r "echo 
msGetVersion();"

# test Python MapScript (actually Python 3.10.1)
- python -c "import mapscript; print (mapscript.msGetVersion())"

Here are some of the specific changes:

 - upgraded MapServer and MapScript (PHP, Python, CSharp, 
Java) to today's 8.0.0-dev

 - rebuilt MapServer plugins (Oracle, Microsoft SQL Server)
 - removed unnecessary folder /ms4w/apps/phpmapscriptng-swig
 - updated /htdocs/quickmap.php
 - added new required ms4w.conf file into /ms4w root and
   set MAPSERVER_CONFIG_FILE location in Apache httpd.conf and

[mapserver-users] PHP Mapscript on Debian 10

[Sven Schroeter via mapserver-users]

Hi,

I am trying to get PHP Mapscript to run stably on a Debian 10 machine.
The installation actually worked fine and everything is running, only 
there is an error after each automatic nightly restart of the Apache 
server.
After that PHP continues to run, but the Mapscript module does not work 
anymore.


This is the error message from Apache after the restart at night:

[Mon Jun 14 00:00:04.851967 2021] [mpm_prefork:notice] [pid 24101] 
AH00171: Graceful restart requested, doing restart
[Mon Jun 14 00:00:05.847274 2021] [mpm_prefork:notice] [pid 24101]

child pid 29129 exit signal Segmentation fault (11)


If I restart Apache manually after that everything runs normal again.


I did the following installation of Mapscript and Mapserver:

1. Installation Apache Postgres GDAL:
apt-get -y install apache2 libapache2-mod-php postgresql-11-postgis-2.5 
gdal-bin

postgresql-11-ogr-fdw && apt-get clean

2. PHP components:
apt-get -y install php-pgsql php-gd php-curl php-mbstring php-sqlite3 
php-zip phpsqlite3 php-bcmath php-xml && apt-get clean

a2enmod cgi && systemctl restart apache2

3. Mapserver 7.6x with PHP Mapscript - own compilation with cmake:

sudo apt-get install libfreetype6-dev php-dev libproj-dev libfribidi-dev
libharfbuzz-dev libcairo-dev libgdal-dev libgpg-error-dev 
libcurl4-openssl-dev

libfcgi-dev

wget http://download.osgeo.org/mapserver/mapserver-7.6.3.tar.gz && /
tar xvf mapserver-7.6.3.tar.gz && /
cd mapserver-7.6.3/
sudo apt-get install cmake
mkdir build
cd build

..
make
sudo make install
echo extension=php_mapscript.so>/etc/php/7.3/mods-available/mapscript.ini

phpenmod mapscript
service apache2 restart

after these installation steps I have a perfectly running PHP version 
7.3.27-1~deb10u1 with Mapscript (MapServer version 7.6.3) but as said 
the Mapscript module error after every nightly restart of Apache.

If I restart Apache manually after that everything runs normal again.
I am now quite at a loss...

Thanks for any advice, unfortunately I am not a Debian (Linux) expert.

Sven




After this

Re: [mapserver-users] HTML Legends with MapServer

[Sven Schroeter]

the templates are usually not very complex, but rather long due to the 
large number of layers, here is a shortened example:

Query templates already support the concept of includes:

so I wonder if it might be possible to extend that functionality to 
HTML legend processing. Do you have a particularly complex example you 
could share with me?

Re: [mapserver-users] Problem with UNION layer and labelling

[Sven Schroeter]

Hi Oliver,
this is a complex SQL statement and I would always store such things in 
a view on the database. Then you can visually check if all data comes as 
it should.
Otherwise it could be due to the encoding of the data records, I 
sometimes had problems with it in the past.
By the way, you can just ask Armin Retterath in your house, he will find 
every error ;-)

Greetings also to Armin

Hi list,

I tried with MapServer 7.0.4 and 7.4.2 to get labels on an UNION layer. The 
labels are OK when I loaded the source layer itself into QGIS, but the UNION 
layer returns an empty picture (using LABELITEM) or the name of the label field 
including the brackets is placed instead of the data (using TEXT inside LABEL).
Furthermore, the variable settings for ANGLE, FONT, SIZE and POSITION don't 
seem to be handled correctly in the UNION layer. The font size and the position 
aren't identical to the source layer. Layers with polygons and no labels are 
drawn correctly!

Re: [mapserver-users] Download Windows binaries of MapServer

[Sven Schroeter]

Hello,
I don't think the ms4w page is available right now. If you need Windows 
binaries, you can also download the version of gisinternals:

https://www.gisinternals.com/release.php
You can quickly download the latest version of ms4w 4.01 here, I just 
put it on our server: https://netgis.de/download/ms4w_4.0.1.zip

[mapserver-users] WFS PHP Wrapper for POST body Request

[Sven Schroeter]

Hi,

I'm using a WFS Wrapper written in PHP with following Code (MS Version 7.x):
...

try {
        $oMap = ms_newMapobj($mymapfile);
    } catch (Exception $e) {
        echo 'Exception: ', $e->getMessage(), "\n";
        ms_ioresethandlers();
        $oMap->free();
        unset($oMap);
        exit;
    }

    $request = ms_newowsrequestobj();


    foreach ($_GET as $k=>$v) {
        $request->setParameter($k, $v);
    }

    foreach ($_POST as $k=>$v) {
        $request->setParameter($k, $v);
    }

    $oMap->owsdispatch($request);
    $contenttype = ms_iostripstdoutbuffercontenttype();

    //Objekt reset
    $oMap->free();
    unset($oMap);

      $buffer = ms_iogetstdoutbufferstring();
      header('Content-Type: application/xml; charset=utf-8');
      echo $buffer;

...

this works fine with GET Request or Post Requests sent from a form.
I have a problem with data I send over the body of a POST request.
So I can get to the data and hand it over, but how?
$postBody = file_get_contents('php://input');

I've already tested it with
$request->loadparams();

Any idea?
Thanks Sven

[mapserver-users] Fwd: Re: [MS4W-Users] transparency with php mapscript

[Sven Schroeter]

Hi all,

I'm fighting with the SWIG PHP MapScript Opacity again and found a very 
strange behavior.


Here is my test script:

include("../includes/phpmapscriptng-swig/mapscript_70400.php");
$map = new mapObj(MAPFILE_PATH.'test.map');

// set image format
$map->selectOutputFormat("image/jpeg");
$oRasterLayer = $map->getLayerByName('tk_rlp_tms_grau');
$oPolyLayer = $map->getLayerByName('grenzen_vg');

$oRasterLayer->setOpacity(10);
$oRasterLayer->status = MS_ON;

$oPolyLayer->setOpacity(30);
$oPolyLayer->status = MS_ON;

// set image size
$map->setsize(1000,768);
$map->setextent(300497,5495624,366043,5558489);

// Bild im MapServer IMAGEPATH abspeichern.
$image = $map->draw();

//Bildname, Extension und Pfad
$picname = md5(rand());
$picext = ".jpeg";

$picpathname = MS_TMP_PATH.$picname.$picext;

// Bild im MapServer IMAGEPATH abspeichern.
$mapimage = $image->save($picpathname,$map); //URL


$imgurl = MS_TMP_URL.$picname.$picext;

//header('Location: '.$imgurl);

echo '';



If I set the width of the image to a number with 2 zeros at the end 
everything works fine.

e.g. $map->setsize(800,814);
or $map->setsize(1000,768);

as soon as I change the value for the width of the image it often 
doesn't work anymore and the layers don't have transparency anymore.

e.g. $map->setsize(801,814);
or $map->setsize(1011,768);

It is extremely difficult to see a pattern here.
All variants work with the old Mapscript.
Is this a bug?

Thanks + Greeting
Sven

[mapserver-users] transparency with php mapscript

[Sven Schroeter]

Hello,

I test current php mapscript versions under Windows and try to give a 
layer transparency.


With mapserver versions < 7 this was possible:

$layer_poly->opacity = 68;

With the version MS4W 3.3.1 with Mapserver > 7 and PHP Mapscript it 
works like this:


$layer_poly->updateFromString('LAYER COMPOSITE OPACITY 68 END END');

In the new version MS4W 4.0.0 with the SWIG API I tried the following 
variants:


$layer_poly->opacity = 68;
$layer_poly->setOpacity(68);
$layer_poly->updateFromString('LAYER COMPOSITE OPACITY 68 END END');

In all variants no error message, but also no transparency.

Any ideas?

Thanks Sven

[mapserver-users] PHP Mapscript Swig

[Sven Schroeter]

Hi,
sorry for the cross-post, but maybe there's someone here who doesn't 
read the ms4w list...


I'm using the new MS4W 4.0.0 and try to build a WMS Wrapper for the new 
PHP Mapscript with Swig.
I am currently writing the complete PHP mapscript code from my client so 
that it runs with both versions, so far this works fine, 
msIO_getStdoutBufferBytes() is the only problem so far...


Here is my Test Code for the last MS4W 3.3.0 with old PHP Mapscript
This works fine trying two example requests with getCapabilities and getMap

#
...

$oMap= ms_newMapObj($mymapfile);

ms_ioinstallstdouttobuffer();

$request = ms_newowsrequestobj();

//Get Request
foreach ($_GET as $k=>$v) {
    $request->setParameter($k, $v);
}

$oMap->owsdispatch($request);
$oMap->free();
unset($oMap);

$contenttype = strtolower(ms_iostripstdoutbuffercontenttype());

//Capabilities Request
if ($contenttype == "application/vnd.ogc.wms_xml; charset=utf-8"){
    header('Content-type: application/xml; charset=utf-8');
    echo ms_iogetstdoutbufferstring();
}

//getMap jpeg
else if ($contenttype == 'image/jpeg'){
    header('Content-type: image/jpeg');
    echo ms_iogetStdoutBufferBytes();
}

...


and here ist the same Code using the new Swig Version:
The getCapabilities Request works fine, not the getMap Request.
I get no picture but only this text:
Resource id #7

#
...

include("../includes/phpmapscriptng-swig/mapscript.php");
$oMap= new mapObj($mymapfile);

msIO_installStdoutToBuffer();

$request = new OWSRequest();

//Get Request
foreach ($_GET as $k=>$v) {
    $request->setParameter($k, $v);
}

$oMap->OWSDispatch($request);

unset($oMap);

$contenttype = strtolower(msIO_stripStdoutBufferContentType());

//Capabilities Request
if ($contenttype == "application/vnd.ogc.wms_xml; charset=utf-8"){
    header('Content-type: application/xml; charset=utf-8');
    echo msIO_getStdoutBufferString();
}

//getMap jpeg
else if ($contenttype == 'image/jpeg'){
    header('Content-type: image/jpeg');
    echo msIO_getStdoutBufferBytes();
}

...


Any idea?

Thanks Sven

Hi,

I have a line Layer and want to change the pattern dynamicly from the

Is it possible?


e.g. I have this working:

            COLOR [linecolor]
            WIDTH 4
            PATTERN 40 10 END
        END
 END  # CLASS


and I want to get the pattern from an attribute:


    CLASS
 NAME "buslines"
        STYLE
            COLOR [linecolor]
            WIDTH 4
            PATTERN [pattern] END
        END
 END  # CLASS

but this dont work. Any hint?

I have no experience with other programming languages at mapserver, so far I

Thank you very much, Sven.

Is it right to use FastCGI for less resource consumption?
What language of MapScript is more suitable the best performance?

Regards.

Hi Vladimir,

the fastest way is probably the CGI variant. You write your mapfiles and 
deliver the data via mapserv and the corresponding parameters.
In the case of PHP you have to build a wrapper, which is no problem. If your 
server runs under windows, this is the better variant, because many firewalls 
close when you call mapserv.exe.
When it comes to custom programming, the php (or python or C# or Java) variant 
has more influence.

On a Windows server just rename mapserv.exe to mapserv and all will be good.

In the case of PHP you have to build a wrapper, which is no problem. If your 
server runs under windows, this is the better variant, because many firewalls 
close when you call mapserv.exe.
When it comes to custom programming, the php (or python or C# or Java) variant

Betreff: [mapserver-users] What is the best way to generate WMS?

Hi list,

There are several tables with a lot of objects in PostGis database.
Fields of the tables contain styles(color, width etc)

The goal is fast getting a single image(WMS) on client .
I am aware about two ways to do it:
mapserv as FactCGI and some kind of MapScript(PHP in my case)

What is the best for performance?
Is there more productive way?

Re: [mapserver-users] What is the best way to generate WMS?

[Sven Schroeter]

I have no experience with other programming languages at mapserver, so far I 
only used php and that works well, e.g. I use a wrapper here:
https://geodaten.naturschutz.rlp.de/kartendienste_nature_protection/mod_ogc/

I developed this on the basis of this example:

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

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

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

Best,

Edward

Most of the battle is identifying the over/under in the data. Have you got

All, 
 
I’m looking for general techniques in how to best manage rendering of
over/under roadway and rail road bridges, etc.
 
My first thought was to use some sort of special overlay layer to handle
this.  But maybe a database appraoch might be better.  I also start to fall
into the problem of having a lot of transporation related layers,   Streets
and Railroads obviously, but the not the so obvious are Alleys, Sidewalks,
Park Trails/Paths, Bike Routes, tunnels, etc.  
 
How to make these all stack nicely.  I generally maintain these things all
in thier own grouping right now as separate datasets.  They originate from
separate authors and are maintained that way too.  Which is why I was
thinking that a DB approach might be the best to make the Z-indexing work.
 
Thoughts?

Re: [mapserver-users] Out-of-memory error due to huge NTv2 shift-file

Hello, Michael,

interesting, I have already experimented with the new NTv2 grid for Mannheim 
and we also use Mapserver + Postgis. 
I didn't have the problem you mentioned, but the test system wasn't in

Betreff: [mapserver-users] Out-of-memory error due to huge NTv2 shift-file

Dear mapservers, 

in our region in Germany a new CRS is introduced (ETRS:25832). For cadastral 
precision a NTv2 grid-shift file has been generated. This uses a very fine grid 
and is now 350MB in size. While we tested this file in our dev environment and 
everything worked fine, our production environment is not able to cope with the 
amount of requests, since it seems, that each mapserver process is opening that 
file and soon Out-of-memory errors appear, until the server is not answering 
anymore. Not sure whether each request is causing the .gsb file to be loaded, 
or only requests that actually invoke a reprojection.

I assume that we can reduce the amount of needed reprojections as soon as data 
is permanently projected to the new CRS, but still some on-the-fly projections 
will be necessary. I am looking for good strategies to handle this problem. 
Could anyone give some advice? 


Cheers, Michael

I guess this happens because of the new COMPOSITE block:

COMPOSITE
OPACITY 100

I remember that I had the same problem, and I had to use 
$layer->updateFromString() to set the opacity. As far as I can recall, this is 
a known issue, no methods to change opacity nor composite are available for PHP 
mapscript.

Hi Steve and Carlos,

thanks for your support. 

When I understand it correctly, I can not use the IN operator in conjunction 
with queryByAttributes in Mapserver 7 (mapscript) ?
I use this function so far for the transfer of different IDs (whether integer 
or string) to read out a subset of POSTGIS tables.
I have now tried the following and it works:

$qstring = "([gid] = '1' || [gid] = '2' || [gid] = '4' || [gid] = '11')";
$query_layer->queryByAttributes("gid",$qstring,MS_MULTIPLE);

Maybe it is possible to get the IN operator back in the future?

Ugh, my bad. At least with the LIKE operator it’s because MapServer doesn’t

maybe that I can come up with a work around for Sven using the native SQL that

The query syntax is given in MapServer expression syntax. I think there’s a

  queryByAttributes("gid", "gid > 100", MS_MULTIPLE) // does not found anything
 
is evaluated as gid = “gid > 100”. Valid but not what you’re looking for. Your 
last example is the right way to do it - queryByAttributes("gid", "([gid] >

then it ignores the qitem.
  queryByAttributes("gid", "100", MS_MULTIPLE) // found one result

  queryByAttributes("municipio", "'GUADALAJARA'", MS_MULTIPLE) // found one

like the first example this evaluates as municipio = "municipio LIKE 'G%'", not 
what you want. See below…

the IN operator works off a delimited list, try queryByAttributes("gid",

  queryByAttributes("municipio", "([municipio] LIKE 'G%')", MS_MULTIPLE); //

This is close, it’s a logical expression but you’re comparing a number against

[mapserver-users] OFFSITE and RESAMPLE in MS 6

Hi,
I changed a project from MapServer 5.6 to MapServer 6.0.2.
I have the problem, that my raster layers look bad, because PROCESSING
RESAMPLE is ignored for rotated GeoTIFF images when OFFSITE is set.
When I take the "OFFSITE 255 255 255" line out, then the RESAMPLE=AVERAGE
setting works and my raster layers look fine, but naturally the single
raster images overlap each other, so I there are white triangles at the
borders/corners.
The same Problem was already posted some times.
I think it could be the wrong sequence of the operations. Maybe in MS 5.6 it
was different?
Is there a solution for it in MS 6?

$datQuery = $layer->queryByPoint($qPoint, MS_SINGLE, 1);
if you want more results:
$datQuery = $layer->queryByPoint($qPoint, MS_MULTIPLE, 1);

Subject: [mapserver-users] setting up raster queries


Hello,
I have a DEM file on my map so that users can click identify and get the 
elevation for the location.  The query works however I get anywhere between 
0 to 2 records returned.  Is there a way to return only a single record on a 
query?

Thanks

[mapserver-users] mapserver >= 5.6 and querys via php-mapscript

[Sven Schroeter]

Hi,
I'm still fighting with mapserver >= 5.6 and querys via php-mapscript.
My code for e.g. making a queryByRect works fine since I use resultsGetShape 
instead of getShape for version 5.6:


//query
@$datQuery = $query_layer->queryByRect($qRect);

//number of objects
$resnum = $query_layer->getNumResults();
echo "number of objects: ".$resnum."";

//if query success
if ($datQuery == MS_SUCCESS) {

//check ms version
 if (ms_GetVersionInt() < 50600){
$query_layer->open();
 }

 //write table
 echo '';

 for ($j=0; $j<$query_layer->getNumResults(); $j++) {
  $result = $query_layer->getResult($j);

 //check ms version
 if (ms_GetVersionInt() < 50600){
$shpobj = $query_layer->getShape($result->tileindex,$result->shapeindex);
}
 else{
$shpobj = 
$query_layer->resultsGetShape($result->shapeindex,$result->tileindex);

 }

  $si = $result->shapeindex;
  $attr = $shpobj->values;
  echo ''.$si.'';
  foreach($attr as $name=>$wert) {
   echo ''.$wert.'';
  }
  echo '';
  $shpobj->free();
 }
//check ms version
if (ms_GetVersionInt() < 50600){
$query_layer->close();
}
echo '';
} // end success

My problem: using ms 5.6 the shapeindex ($result->shapeindex;) is only an 
temporal arrayindex (0-x) and not the "real" shapeindex I get with 
mapserverversions < 5.6.
How can I get the "real" shapindex of my shapes using ms 5.6? I need this 
for pointing on single shapes in another program.


Thanks
Sven

Re: [mapserver-users] rasterquery

[Sven Schroeter]

Frank,

thank you for the hint, I have found that it only doesn't work with a ESRI 
Grid.

With a .tif / geotif the rasterquery works without problems. Is this a bug?

[mapserver-users] rasterquery

[Sven Schroeter]

Hi,
I try to make a raster query using phpmapscript
My layer in the mapfile:

# DHM ESRI Grid
LAYER
NAME "mydhm"
DATA "dhm_vg/grid/dhm_vg" #grid dir
STATUS default
TYPE RASTER
TEMPLATE "template/query.html"
END

My php code:

//load mapfile
$map= ms_newMapObj($mapfilepath.'\map.map');

//create point
$qPoint = ms_newPointObj();
$qPoint->setXY(2554032,5521435);

//set layer
$layer = $map->getLayerByName("mydhm");

//query
@$datQuery = $layer->queryByPoint($qPoint, MS_SINGLE, 1);

if ($datQuery == MS_SUCCESS) {
 echo "OK!";
}

this works fine with mapserver 5.02 but there is no result  with mapserver 
5.6.1


apServer version 5.6.1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP

[mapserver-users] OGR/PHP Extension encoding

[Sven Schroeter]

Hi,
I'm using the OGR/PHP Extension to convert data from a postgis database to 
ESRI Shape by using the actual extent of my mapclient.
This works fine, you can test the "Export-Button" (in the left panel) on my 
client, choose for example "Naturschutzgebiete" in the dropdown of the 
export-dialog:

http://map1.naturschutz.rlp.de/mapserver_lanis/
My database is utf-8 encoded and I want to export my attribute-data to 
Latin1.

Is there a possibility to tell  ogr via php to change the encoding?
With pgsql2shp I can set PGCLIENTENCODING=LATIN1 and it works. This doesent 
work with ogr2ogr.

Any idea?
Thanks
Sven

Hi,
thank you very much, shapeObj resultsGetShape is the solution.
resultsGetShape works fine.
But I don't understand why shapeObj getFeature is in the documentation?

Why there comes no array in $attr = $shpobj->values; ?

Re: [mapserver-users] ms_newprojectionobj

Hi Jeff,
thank you for your reply.

I got the failure:
in my proj-file the epsgcode is following:

<31466> +proj=tmerc +lat_0=0 +lon_0=6 +k=1.00 +x_0=250 +y_0=0 
+ellps=bessel +units=m +no_defs  no_defs <>


But it must be:

<31466> +proj=tmerc +lat_0=0 +lon_0=6 +k=1.00 +x_0=250 +y_0=0 
+ellps=bessel +datum=potsdam +units=m +no_defs  <>



There is no definition of the datum. That makes the wrong coordinates.
I didn't see it because one Server had a PROJ_NAD System variable on the 
correct proj-file

You could test it on both servers with a Windows package like MS4W 
(http://www.maptools.org/ms4w), so you are sure that the same library 
versions are used.

Hello Sven,

I suggest you search for a file called epsg on both systems. It is a

Search both for <31466> and  <4326>
Compare the lines and check to see they match.

Good luck!

This is something that I'm interested in as well, could I please ask you to

BTW: I think you can expose a new InfoFormat by setting the

[mapserver-users] GetFeatureInfo in XML

[mapserver-users] apache warning TIFFReadDirectory

[Sven Schroeter]

Hi,
I'm working with MapServer version 5.0.2 (php mapscript) on a Apache 2.2.4 
webserver.

Everything works fine but Apache logs following warning:

Warning 1:
TIFFReadDirectory:Unknown field with tag 37522 (0x9292) encountered

I'm using raster-data (.tif with .tfw) in an image catalogue.
Any idea?
Thanks

[mapserver-users] get connectiontyp via mapscript

[Sven Schroeter]

Hi all,

I try to get the connectiontyp via mapscript, this works:

$layer = $map->getLayerByName($qlayer);
$contyp = $layer->connectiontype;

I get back a "1" for shapefiles and a "6" for Postgis-layers.

Where can I find the other types?

Thanks
Sven

[mapserver-users] incorrect minscale using php mapscript

[Sven Schroeter]

Hi all,

I'm using php mapscript (MS 5.2.1 on Windows) in my client and have problems 
with the minscale from the WEB-Section of my mapfile.


For example if I set
MINSCALE 1

on an imgsize with 1618 x 907 pixels the minscale for creating an image is 
17848

on an imgsize with  822 x 503  pixels the minscale is 16355

I get the same wrong scale setting the minscale with mapscript:
$map->web->set(minscale, 1);

where is the error?

Thanks
Sven

Re: [mapserver-users] Displaying points on the map only for certaintime period

[Sven Schroeter]

Hi,
that depends on your client application. For example you can update the map 
via php-mapscript with  ajax. For a periodical request I use the prototype 
javascript framework:

http://www.prototypejs.org/api/ajax/periodicalUpdater

Hi,
   I have to display a point on the map only for 5 seconds. After 5 seconds 
the second point from the database should be retrieved from the database 
and displayed.This process continues till all the points in the database is 
displayed.Can anyone tell me how to do this..


Thanks.

[mapserver-users] query case insensitive

[Sven Schroeter]

Hi all,

I'm using the queryByAttributes-function of PHP-Mapscript with the LIKE (~) 
operator for strings (out of a POSTGIS-table):


$queryString = "nom_bande ~ 'WT'";
$queryItem = "nom_bande";
@$datQuery = $layer->queryByAttributes($queryitem,$queryString,MS_MULTIPLE);

Every dataset that contains 'WT' comes as result. But this is case 
sensitive, if I try

$queryString = "nom_bande ~ 'wt'";
there is no result.

Is it possible to make the query case insensitive?

Thanks
Sven

Re: [mapserver-users] GetFeatureInfo for number in textfield

[Sven Schroeter]

Steve,
it's really the problem with the template substitution string, with "mynr" 
it works, thank you very much!

nr is also a template substitution string (means number of results) in 
mapserver templates so I'm guessing
that's being returned instead of the column values. A value of 1 for every 
result seems to confirm that. The
work around would be to rename the column in your SQL statement (eg "nr as 
mynr").

Hi,
My System: Mapserver 5.02 on Win 2003 Server with Postgres/Postgis 8.3/1.3.
I make a GetFeatureInfo Request from a WMS-Service:

With
INFO_FORMAT=text/plain
every field from my Postgis-table comes with a correctly result:
For example

GetFeatureInfo results:

Layer 'naturschutzgebiet'
 Feature 13288152:
   geodb_oid = '175'
   objectid = '175'
   nr = '23308'
   name = 'Ernstberg'
   ...

The Field "nr" is a textfield with some numbers as strings, for example nr
= '23308'.
If I try to get a result via html-template (INFO_FORMAT=text/html)
everything works fine except the field "nr".
For this field I get in every query a "1".

any ideas?

Thanks
Sven

[mapserver-users] toWKT() method

[Sven Schroeter]

Hi all,

I'm using PHP-Mapscript with GEOS (Mapserver 5) to get a WKT-String from a 
POSTGIS-Table:

$mywkt = $shpobj->toWKT();

Everything works fine for POLYGON, LINESTRING and POINT - tables.
If I try the "toWKT()" Method for MULTIPOLYGON-Tables I get back a POLYGON 
WKT-String.
What can I do?

Thanks,
Sven

Re: [mapserver-users] Accessing raster cell values

[Sven Schroeter]

Hi,

if you have access to  the mapfile, you can make a queryByPoint  with
mapscript (i.e with an ajax-function)
You have to send your point-coordinats to the script like this:

$coord = split(',',$_POST["coord"]);
dl('php_mapscript.dll');

//load mapfile
$map= ms_newMapObj($mapfilepath.'\yourmap.map');

//create point
$qPoint = ms_newPointObj();
$qPoint->setXY($coord[0]*1,$coord[1]*1);

//set layer
$layer = $map->getLayerByName("your_rasterlayer");

//Pointquery (Single)
@$datQuery = $layer->queryByPoint($qPoint, MS_SINGLE, 1);

//if success
if ($datQuery == MS_SUCCESS) {
for ($j=0; $j<$layer->getNumResults(); $j++) {
   $result = $layer->getResult($j);
  $layer->open();
  $shpobj = $layer->getShape($result->tileindex,$result->shapeindex);
  $attr = $shpobj->values;
  //echo round($attr["value_0"],2);
  $rasterdata = round($attr["value_0"],1);
  print 'My Data: '.$rasterdata.';
  $shpobj->free();
}
}
 else{
print 'no Data';
 }

Greetings
Sven

Subject: [mapserver-users] Accessing raster cell values



Hello List,

This question may be a general newbie GIS question and not solely  related 
to Mapserver, so apologies if I'm posting to the wrong place.


I am serving a GeoTiff via Mapserver using WMS, and displaying it  using 
OpenLayers, so far so good.
I need to be able to click on a point on the map and display the  value 
held within that particular Raster cell.
Can anyone suggest what mechanism I should use for this? WCS looks  like 
it might be the thing I need, but I'm having difficulty finding  much in 
the way of examples and instructions.
I've followed what examples there are and all I can get Mapserver to 
return using WCS, is a Geotiff with every pixel set to zero.
So I've obviously not got it working correctly, and even if it were  I'm 
not sure how to get the information I need out of the returned  Geotiff 
when my client is OpenLayers.


Can anyone suggest a way to access a raster's values when it is  served by 
Mapserver and viewed using OpenLayers?


Thank you

Andrew Mason
