Hi Michael, The -e extents option in osgdem is geared around lat/longs as you've found out. It should be possible to provide extents in other coordinates given some further work to osgdem, exactly what this should be I can't say off the top of my head.
Through the summer and into Autumn I'll be doing alot of work on the VirtualPlanetBuilder project, as part of this work I'll be developing replacements for osgdem, I bear in mind the issue of different coordinate systems for specifying things like extents.

Hi, I'm trying to create a textured model of a certain area with the osgdem commandline tool. I define the target area via the e-parameter (extents of the model to generate) in >latitude/longitude< >osgdem -t wholeArea.tif -e 7 -46 1 1 -o partOfTheArea.osg It works great if the source imagery is also in lat/long style. But this seems to fail if the source imagery is not in lat/long-style, like UTM data, although all necessary information for reprojection to lat/long is provided by the geoTIFF header. (used UTM geoTIFFs : http://mpa.itc.it/markus/ecopat2004/landsat_tm7_20010730.tar.gz ) The result is a model without texture. What's the reason for it ? Can I achieve the expected result in another way ?
