Thanks for everyones help and quick responses. I can create the 8 geotiff files (approx 1.8Gb each).
Just some more questions. 1) To create the elevation file using topography (2km) png file is the following command correct gdal_translate srtm_ramp2.world.21600x10800.png topo.tif gdaladdo -r average topo.tif 2 4 8 16 32 64 128 256 2) To build the OSG earth output file (ive) using the 8 geotiff and elevation data file is the following command correct? osgdem --bluemarble-west -t A1.tif -t A2.tif -t B1.tif -t B2.tif --bluemarble-east -t C1.tif -t C2.tif -t D1.tif -t D2.tif --whole-globe -d topo.tif --geocentric -l 12 -o earth.ive 3) If the above command is incorrect, do I use gdal_merge script to create a west and east tif by creating a mosiac image. For example use A1.tif, A2.tif, B1.tif, and B2.tif to create west.tif. 4) What should I expect the total storage size of all the tiles to be? 5 Gb? Thanks again.

Better then that here are the geotiffs http://telascience.sdsc.edu/tela_data/BM/geotiff/ Here is the basic script I used todo this http://telascience.sdsc.edu/tela_data/BM/world_big/geotif/bmng_scripts/m ake_ world.topo.3x86400x43200.py Will need to be tweaked for your local setup etc Enjoy Norman _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/ _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
