[mapserver-users] projecting in degrees
I have shapefiles that are stored in degrees and they are displayed in degrees if there are no projections in the mapfile. When displayed like this, they look like UTM world projection. However, I need to display it in old style mercator where greenland is really big. I can get mapserver to project as mercator, but it always converts to meters. I would like to project my shapefiles in degrees. Is this possible? I need to because I handle extents and annotation points in degrees. Thanks. ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
RE: [mapserver-users] shp/dbf file's name
If I understand your question correctly you are attempting to do something similar to what I have where I am coloring polygons in a shapefile based on a numeric value stored in a frequently-updated CSV-file. As long as you have a field in both files that you can join on it ought to work. I used the OGR connection type as briefly discussed in a previous post, http://www.mail-archive.com/mapserver-us...@lists.umn.edu/msg13477.html This is the type of syntax you appear to need: CONNECTIONTYPE OGR CONNECTION "/var/www/demodata/a.shp" //path to the shapefile DATA "SELECT a.ID, b.NAME FROM a LEFT JOIN '/var/www/demodata/b.dbf'.b ON a.ID=b.ID" In my case the LAYER section in the mapfile looks like this, where "FIPS" is the field I join the files on. LAYER NAME 'parishes_on_boiladv' CONNECTIONTYPE OGR CONNECTION "myshapefile.shp" DATA "SELECT * FROM myshapefile LEFT JOIN 'full_path_to_file_named_bwa.csv'.bwa ON myshapefile.FIPS = bwa.FIPS" STATUS on TYPE polygon CLASSITEM "PercentageOut" CLASS EXPRESSION ([PercentageOut] > 0 AND [PercentageOut] <= 10) NAME "0 - 10%" STYLE COLOR 56 168 0 END END #class (continues with several more classes).

RE: [mapserver-users] maps all look squished
I'm wondering how the maps are being displayed. The original sample looked like there was a x-stretch.

What if the external dbf file doesn't have the same number of rows as the number of features in your ShapeFile? The dbf format is pretty primitive. Your best bet is to actually add to your ShapeFile the data that is now in your external file.

[mapserver-users] shp/dbf file's name
Hi, I would like to know if it's possible to draw geometries from a shp file according to attributes from a dbf but with 2 files named differently. For instance : LAYER NAME layer1 DATA shapefile1.shp CLASS EXPRESSION ([col1]=1) STYLE END END END Where col1 is a field inside a file storing attributes (dbf/csv/txt/...) but not named shapefile1.dbf I already tried to use the JOIN option but I think it's inappropriate for my purpose since "You cannot use joins to affect the look of a map" (http://mapserver.org/mapfile/join.html) Thanks for your help !

Re: [mapserver-users] Mapserver tile generation - google maps
I'll try updating GD. Thanks. TileCache is probably not an option, as the color of the data changes every minute. That would mean that tilecache has to reset its data every minute. Not sure if that is possible, or rather, wanted behaviour. OpenLayers would have been a good option, but for some odd reason the client wants the 'real google maps' interface :). In any case, thanks for your help.

Re: [mapserver-users] maps all look squished
Hi, What is the projection of your layer data, what is the projection for the output, and how do you request the image from Mapserver? -Jukka Rahkonen- -Alkuperäinen viesti- Lähettäjä: mapserver-users-boun...@lists.osgeo.org puolesta: Josh Jordan Lähetetty: pe 20.8.2010 6:16 Vastaanottaja: mapserver-users@lists.osgeo.org Aihe: [mapserver-users] maps all look squished No matter what projection I use, my maps always look stretched too wide, or squished. What could be the problem? What can I do? Attached is a picture of the problem, the top michigan is correct, the bottom one is generated in mapserver. Can anyone from Michigan suggest a projection where the state looks the most correct?

Re: [mapserver-users] refactoring STYLEs ?
Hi, You can use INCLUDE everywhere in your mapfile for reading definitions from a text file. -Jukka Rahkonen- -Alkuperäinen viesti- Lähettäjä: mapserver-users-boun...@lists.osgeo.org puolesta: Clément MONIER Lähetetty: pe 20.8.2010 14:48 Vastaanottaja: 'mapserver-users@lists.osgeo.org' Aihe: [mapserver-users] refactoring STYLEs ?

[mapserver-users] Mapserver tile generation - google maps
Hi all, I noticed a similar post regarding symbol issues, but there was no solution. My Google maps tiles are currently clipped at the tile itself. This results in rather unwanted behaviour: http://fileshare.myroute.be/exchange/Capture.PNG I'm not 100% sure that this is mapservers' 'issue' , or google maps issue. If anyone would have further tips to spice up the graphics even more, I'd be more than glad to hear them :). Thanks.
