Hi Cory, If you set the value of interpolateTerrain=false in the call to readHeightField in Dataset.cpp, things will hopefully work out for you. I've looked through the code and I can't see anything glaringly obvious as to why files with embedded geospatial coordinates work fine but it inverts terrain when specifying the geotransform on the command line.

I think there was a problem with specifying the geotransform on the command line using the -xx -yy switches rather than embedding the information in the input file but it never got resolved. I'll take a quick look at it and see if I can figure anything out and get back to you. Jason -----Original Message----- From: [EMAIL PROTECTED] on behalf of Weber, Cory C.

I'm sure this has been asked 10,000,000 times; I have a tiff 32bit grayscale image that I'm using as the DEM and a 24 bit tiff that I'm using for the texture, but when I run osgdem it creates the terrain vertically inverse of the texture... what am I doing wrong? (they match in my image viewer). I'm using: osgdem --xx 9.183 --yy 9.177 -d t:\visualization\Cory_data_070112\Area1_DEM.tif -v 2.5 -t t:\Visualization\Cory_data_0701012\Area1_img.tif --PagedLOD -l 7 -o t:\Visualization\GraphicsData\Terrain\Area1Color_071501\AreaColor_071501 .ive Cory C Weber Visual Spatial Technician Environmental Science Division Argonne National Laboratory 9700 South Cass Avenue Argonne, IL 60439 [EMAIL PROTECTED] 630-252-7498 _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
