Hey,
Did you find out anything? I have been looking for data to create an
earth model myself. I did a search for the tiff files you listed and
found them. I tried the following command:
osgdem --bluemarble-west -t ../land_shallow_topo_west.tiff
--bluemarble-east -t ../land_shallow_topo_east.tiff--geocentric -l 12 -o
earth.ive
Here is the output I received:
--bluemarble-west GEOGCS["WGS 84",DATUM["WGS_1984",SPHEROID["WGS
84",6378137,298.257223563,AUTHORITY["EPSG","7030"]],TOWGS84[0,0,0,0,0,0,0],AUTHORITY["EPSG","6326"]],PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]],UNIT["degree",0.0174532925199433,AUTHORITY["EPSG","9108"]],AXIS["Lat",NORTH],AXIS["Long",EAST],AUTHORITY["EPSG","4326"]]

-o earth.ive

Error: no scene graph to output, no file written.
I have the 500m blue marble images in the same directory as the data
files. I am learning. Just wanted to show what I tried and see if you
had figured anything out.
Thanks,
Michael
