I was wondering if anyone subscribed to this list ever heard of GeoTIFF? This is an extension to TIFF that allows a TIFF image to be georeferenced and geocoded. Even though I could find some information about it. It is hard to get something recent but also hard to find World GeoTIFF images of terrain ONLY and not MAPS, (roads/highways) more like a relief map with attention to elevations and not city streets.

I am particularly interested in finding freely available Wor;d GeoTIFF images that have encoded geospecific information in the header of the file. I can then import the image using MultiGen Creator Pro by into the Creator texture pallette to create a texture that would be more "realistic" then the contour colors that Creator now produces. Creator will read the header and apply the appropriate information into an .attr for the geotiff.

I am looking for a 'WOW' effect for my 3D terrains. These 3D terrains are created by converted DTED1( a uniform matrix of terrain elevation values with post spacing every 3 arc seconds, approx 100 meters. The information content is approximately equivalent to the contour information represented on a 250,000 scale map) using readdma, then reading the converted file into Creator which then builds OpenFlight files. The files are external and read in by one master file, therefore, the texture needs to be created while building the ded database.

I found that there is a lot of information out there but I haven't been able to narrow my search to specific world GeoTIFF images of terrain elevation ONLY.

Any leads will be appreciated.
