Hi Looch, You shouldn't need to preprocess the data at all, save for creating the overlays using GDAL to help reduce aliasing artifcats associated with GDAL downsamping the data on the final database build. This step isn't critical though, its just a image quality step. I'd recommend just going for the main database pager generation run to make sure things are working sweetly first.
You line: osgdem --PagedLOD --bluemarble-west -t west.tif --bluemarble-east -t east.tif --whole-globe -d topo.tif --geocentric -v 1.0 -l 12 -o earth.ive Could be simplified a little as --PagedLOD is the default, and -v 1.0 is the default so: osgdem --bluemarble-west -t west.tif --bluemarble-east -t east.tif --whole-globe -d topo.tif --geocentric -l 12 -o earth.ive Should work fine. As the parameters to osgdem can be a bit long winded I typically place the osgdem call into a shell script and simply run this when I need to rebuild. This way if I make a mistake in the options I can simple stop the build, edit the option, and rerun.
