[mapserver-users] contours in mapfile

[Fawcett, David (MPCA)]

Oz, 

In looking at your layer definition, you have defined a layer extent in coordinates that don't appear to match the spatial reference system you have defined for that layer in the projection block.  

It looks like you have meters or feet in your extent and the units for the projection that you have defined are decimal degrees.   

I would suggest getting rid of your layer extent unless you really need it.  Make sure that the projection that you have defined in your layer matches the projection of your data.  

At the map level (you didn't include this part of the map file), make sure that the units of your map extent match the projection of your map.  

The best approach is to simplify your map file as much as possible to get it working.

David.

Subject: [mapserver-users] contours in mapfile

Hi Everyone,

I am trying to display an ESRI ASCII Raster with map file in a contoured form.

Despite following the documentation here:
http://mapserver.org/input/raster.html#how-are-rasters-added-to-a-map-file
I fail, and get an empty map...

Here's is what I try in the mapfile:

I also attach the raster file as zip.

Can someone tell me what am I doing wrong ?

Thanks in advance !
