Hi all,

Has anyone succefully added a USGS DEM's to a Mapserver mapfile?

I would like to build a wms service with some USGS DEM's but I keep on getting blank page when I do a wms getmap request. The getcapabilities request seems okay but the LatLonBoundingBox element doesn't show up for this layer.

 

Anyone has an idea of what is going wrong?

 

I checked my Mapserver executable using the "-v" flag  and I have GDAL. I also checked out what formats are available using the "gdalinfo -formats" command and I found USGSDEM ( http://www.gdal.org/frmt_usgsdem.html ) in the list.

 

 

Thanks

Hi,

 

why are you using a WMS to serve USGS DEMs, apart from a pretty black and white picture you aren't getting any data!!

 

MapServer supports the Web Coverage Service (WCS) http://mapserver.gis.umn.edu/doc/wcs-server-howto.html and I am in the process

of writing a document on how to use it for DEMs (USGS 16 bit geotiffs), and other formats, let me know if you get stuck.
