[mapserver-users] Vector maps from different vendors with different world coordinates

[Ed McNierney]

Jan -

It appears that your raster data is possibly projected in the UTM projection (?) and your vector data is unprojected in decimal degrees.  MapServer can handle and combine these just fine, but you will need to know all the details of the projection used to create your raster image.

different world coordinates


Hi folks,

At the moment I do some experiments with mapserver (great piece of 
software, BTW). I've downloaded two demo sets (a vector based and a 
raster based from different vendors) covering parts of Berlin, Germany.

The problem is that they seem to use different world coordinates. The 
raster map is shown when I use the command EXTEND 797668 5827367 800464 
5830167 in the mapfile. The vector map, covering the same area, needs 
EXTEND 61.59 34 61.83 34.14.

Is there a possibility to rescale one of the maps so it matches the 
other one? Maybe some parameteres in the LAYER definition of the mapfile?

And, last question... is there a official "standard" for world 
coordinates in shape files? I think everyone is used to measure in 
degrees from the zero meridian and the equator.

Thank you in advance,
Jan
