[mapserver-users] Installing MapServer on Windows

Mon Jun 30 09:34:01 PDT 2014

Hi All,

If you are dealing with an invariant projection for your overall MAP and an invariant one for each layer displayed, consider embedding the definition (copied from the epsg file) as one or more hard-coded PROJECTION statements embedded in the mapfile.

For example,  Web Mercator (3857 is defined within the epsg file as:
  # WGS 84 / Pseudo-Mercator
  <3857> +proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +wktext  +no_defs <>

In place of a mapfile statement such as:
  PROJECTION 'init=epsg:3857'

you could follow Example 3 from http://mapserver.org/mapfile/projection.html; the mapfile could contain:
  PROJECTION 'proj=merc' 'a=6378137' 'b=6378137' 'lat_ts=0.0' 'lon_0=0.0' 'x_0=0.0' 'y_0=0' 'k=1.0' 'units=m' 'nadgrids=@null' 'north' 'no_defs' END

If this is feasible in your context you would save yourself the elapsed time associated with file open/file read operations against the epsg file.

Jukka,  thank you for the reminder on -t_srs, I had forgotten about that.
It makes sense if using the shapefile index to build that in the srs you plan to output. Now that I have been reminded of that feature of gdaltindex I can see that would be faster than parsing a large vrt file.
Thanks.

Hi,

On IIS systems I often have to set the PROJ_LIB system environment variable, to the location of the 'epsg' file, and then reboot the server, such as:

  Variable: PROJ_LIB
  Value: C:\ms4w\proj\nad

Hello..! ?:-)

I'm having a map in browse mode with a simple function taken from the tutorial 1.9 in?http://demo.mapserver.org/. ?I use ogrinfo in order to get the extent and enter it to the mapfile. When I click on the image I get the following error "msCalculateScale(): General error message. Invalid image extent, minx=-1.000000, miny=-1.000000, maxx=-1.000000, maxy=-1.000000."?

When I run it map mode everything is OK but in browse mode it's gives me that. Does it have to do with the UNITS maybe??

Thanks!?

Hello list..!!

I'm using mapserver 6.2.0. ?The command mapserv -v gives me the output:

MapServer version 6.2.0 OUTPUT=PNG OUTPUT=JPEG SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=ICONV INPUT=JPEG INPUT=SHAPEFILE

I assume there are some things missing here like proj, gdal, wfs and wms. Can I have some help in reconfiguring it??

Thanks a lot?
