Re: [mapserver-users] queryByAttributes on PostGIS-Layer
Found the problem (thanks to Nicol ;-)
Code:
@$myQuery = $layer->queryByAttributes('nr_','7', MS_SINGLE);
must be changed to:
@$myQuery = $layer->queryByAttributes('nr_','nr_=7', MS_SINGLE);
Is this a bug?

Subject: [mapserver-users] queryByAttributes on PostGIS-Layer
Hallo list,
My test-system: Mapserver 5.02 on WinXP and postgreSQL 8.2
I try to make some querys via php-mapscript for a postgis-layer:
queryByPoint,queryByShape and queryByRect is no problem.
queryByAttributes always return "no result" (field 'nr_' is an integer)
If I use a shapefile for the same data (biogasanlagen.shp)
queryByAttributes works fine.
mapfile:
...
LAYER
NAME "biogasanlagen"
TYPE point
STATUS on
CONNECTIONTYPE postgis
CONNECTION "user=postgres password=xyz dbname=mydb host=localhost
port=5432"
DATA "the_geom from biogasanlagen using unique gid"
#DATA biogasanlagen.shp
TEMPLATE void
CLASS
Name "biogasanlagen"
OUTLINECOLOR 128 70 0
COLOR 230 70 0
SYMBOL 'circle'
SIZE 12
END # CLASS
TRANSPARENCY 88
TOLERANCE 8
END
...
php-Code:
...
$layer = $map->getLayerByName("biogasanlagen");
@$myQuery = $layer->queryByAttributes('nr_','7', MS_SINGLE);
...
any idea?
Thanks Sven

[mapserver-users] bgd_i.lib?
Hi All, I'm trying to compile MapServer 5.0.2 on windows XP using MSVC 7.1 and the MapServer buildkit. The buildkit includes the source for GD-2.0.35, which is the latest stable release of GD. I followed the instructions to build GD from the readme, and successfully built GD, but it doesn't build a bgd_i.lib file. There is a bgd_a.lib and a bgd.lib file though. I've tried pointing the MapServer nmake.opt file at both of those files, but it always fails to build due to unresolved external symbols, all related to GD. Where do I get the bgd_i.lib file from?

RE: [MAPSERVER-USERS] Displaying population density with Mapserver
Faldor, When you have point coordinates stored in a text file, there really is no way to encode/attach the projection definition. Even if you could, it doesn't sound like you really know what spatial reference system (SRS) or projection that it is in. The key to projecting to another SRS or translating ground units to another measure (from degrees to meters) is knowing what the current SRS of the data is. Since your data is worldwide and it is unprojected (lat/lon), a good first guess would be to assume that it is unprojected with using the WGS84. Try defining your layer projection by including this block in your layer definition. PROJECTION "init=epsg:4326" END David. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Pierre-Benoit Besse Sent: Wednesday, May 28, 2008 4:11 AM To: Fawcett, David Cc: mapserver-users@lists.osgeo.org Subject: Re: [MAPSERVER-USERS] Displaying population density with Mapserver Well, I confess, I'm new to GIS applications and I do not know a lot about projections.

Regards 2008/5/27 Fawcett, David <[EMAIL PROTECTED]>: Before you create lots of different layers to simulate symbol scaling, you may want to try something else. It has been a long time since I have played with scaled symbols, but give it a try. You should be able to scale the symbols by setting a SYMBOLSCALE in the LAYER object. This is the scale at which you want the symbol to appear at the SIZE stated in the map file. You may want to modify STYLE MAXSIZE if you think that you will want your symbols to be larger than 50 pixels. Another completely different approach that just came to my mind would be to use ground units (e.g. meters) to set the size of your symbol. To do this, set LAYER SIZEUNITS to meters. Calculate the size of a symbol in meters on the ground that will touch adjacent symbols, or give you the desired amount of space between the symbols. That way, the symbols should scale consistently.

[mapserver-users] International characters in text paramater
Hi! Tried to find a answer to this but was unable to. I am trying to use Norwegian characters in the text parameter in the class object. I set "Text (Lysløype)" in the map file but this does not work. How can I do this correctly? Example follows: LAYER # Lysloype NAME Lysloype TYPE line STATUS default DATA bygg/lysloype MAXSCALE 2 TRANSPARENCY 80 LABELMAXSCALE 2000 CLASS STYLE COLOR 255 255 0 # Gul farge. SYMBOL "point_line" SIZE 4 END STYLE COLOR 255 255 0 # Gul farge.

[mapserver-users] geotiff raster optimization
Hi List! First of all, i would like to tell I'm a newbie with these issues, and hardy understand everysingle concept involving geo-references and projections and stuff like that. I have been using mapserver for about a month, but right now i'm stuck with some optimization issues i am about to explain. I'm building a map based in images i generate from scratch. Let's say i have one picture per country. Those pictures are based in a huge png file 1x14660 pixels. So lets say i have my own projection system. I have isolated every single country in the world in its own image file, and i have managed to get the xmin, xmax ymin ymax coords for every country. The size of each country depends on a few concepts which would be long to explain... but every country will have a different size. Alltought mapserver manages that correctly. Here's an example of a file * in my png images directory: TR.png: PNG image data, 1200 x 400, 8-bit colormap, non-interlaced TT.png: PNG image data, 1400 x 1400, 8-bit colormap, non-interlaced TW.png: PNG image data, 1200 x 1000, 8-bit colormap, non-interlaced TZ.png: PNG image data, 800 x 800, 8-bit colormap, non-interlaced UA.png: PNG image data, 1000 x 600, 8-bit colormap, non-interlaced UG.png: PNG image data, 400 x 400, 8-bit colormap, non-interlaced US.png: PNG image data, 5800 x 3800, 8-bit colormap, non-interlaced UY.png: PNG image data, 400 x 400, 8-bit colormap, non-interlaced UZ.png: PNG image data, 2400 x 1400, 8-bit colormap, non-interlaced (so you got the idea right?) The total size of the pngs is 50 MB (but expected to be much bigger). So for every image of each country i do this procedure: [*] pngquant, so i downsample my PHP-GD generated 24 RGB PNGs to 8 colormaps with a real acceptable quality. (i have had some trouble with the color i used as a background (and later defined as OFFSITE), because pngquant changed it. pure white (#FFF) seems to work fine later). I think this step is useless, because later, i make mapserver generate the image as a jpeg... or it isn't?? [*] gdal_translate -of GTIFF -co TILED=YES -a_ullr xmin ymax ymin xmax my.png new.tiff which from what i have understood, uncompress all the image data (nice to mapserver) and also puts those extend variables inside the image file. [*] gdaladdo -r nearest file.tiff 2 4 8 16 32 64 128 1000 which i think puts "thumbnails" of the huge picture, inside it. So mapserver access to less amount of data when the zoom is not far enough. Then, with all my tiff files, i run the following command: gdaltindex world.shp *tiff which generates world.shx world.shp and world.dbf. The size of all the generated tiffs is around 500MB (which is not much for mapserver right?) my .map file looks like this: MAP NAME "World" SIZE 750 550 IMAGECOLOR 83 83 83 IMAGETYPE png24 EXTENT -1 -7330 1 7330 OUTPUTFORMAT NAME png24 DRIVER "GD/PNG24" MIMETYPE "image/png" IMAGEMODE RGB EXTENSION "png" END LAYER STATUS DEFAULT TYPE RASTER NAME "MUNDO" TILEINDEX "world.shp" OFFSITE 255 255 255 END END As a frontend I use openlayers, so I actually think the imagetype and output format get overwritten by the openlayers software, which adds to every request to the cgi the imagetype=png variable, so I'm pretty sure the images that are generated by mapserver, are jpegs (smaller size than png and png24, and really acceptable quality). The main problem of the system is performance. It takes about 40 secs to generate the first level of zoom in the openlayers front-end (and about the same time, every time you zoom in). If it's usefull, i have compiled a 5.0.2 version of mapserver with this configure options: ./configure --with-gdal --with-fastcgi --with-png12 --with-gd I have develped a cache system (PHP based), which simply acts as a proxy for mapserver. I guess i could use tilecache or geowebcache... but the idea of the system, is to be running permanently: every country will be regenerated with a new picture every few minutes (so i guess a cache system woudln't do the trick...). So thanks for reading this far, and i would really appreciate if someone could give me some light. thank you for reading this far ;) -- Javier Infante <[EMAIL PROTECTED]> Irontec ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
[mapserver-users] queryByAttributes on PostGIS-Layer
Hallo list,
My test-system: Mapserver 5.02 on WinXP and postgreSQL 8.2
I try to make some querys via php-mapscript for a postgis-layer:
queryByPoint,queryByShape and queryByRect is no problem.
queryByAttributes always return "no result" (field 'nr_' is an integer)
If I use a shapefile for the same data (biogasanlagen.shp) queryByAttributes
works fine.
mapfile:
...
LAYER
NAME "biogasanlagen"
TYPE point
STATUS on
CONNECTIONTYPE postgis
CONNECTION "user=postgres password=xyz dbname=mydb host=localhost
port=5432"
DATA "the_geom from biogasanlagen using unique gid"
#DATA biogasanlagen.shp
TEMPLATE void
CLASS
Name "biogasanlagen"
OUTLINECOLOR 128 70 0
COLOR 230 70 0
SYMBOL 'circle'
SIZE 12
END # CLASS
TRANSPARENCY 88
TOLERANCE 8
END
...
php-Code:
...
$layer = $map->getLayerByName("biogasanlagen");
@$myQuery = $layer->queryByAttributes('nr_','7', MS_SINGLE);
...
any idea?
Thanks Sven

Re: [MAPSERVER-USERS] Displaying population density with Mapserver
Well, I confess, I'm new to GIS applications and I do not know a lot about projections. I understand I have to tell MapServer what is the projection of each layer I use in the mapfile, but using ogrinfo on my shapefiles tells me that : Layer name: pop_density Geometry: Point Feature Count: 249937 Extent: (-180.00, -56.00) - (179.75, 83.50) *Layer SRS WKT: (unknown)* latitude: Real (24.15) longitude: Real (24.15) densite: Real (24.15) I generated this shapefile from a CSV file with 3 columns : latitude, longitude, density_value. Did I have to define a projection then ? How do I do that ? Best regards, Faldor 2008/5/27 Fawcett, David <[EMAIL PROTECTED]>: > Have you defined an output projection for your map and input projections > for each of your layers?
