well, technically the Dec 2004 image IS the most recent, but the idea of Jan-Dec is to show variation in ice cover and vegetation throughout the year -- not that they gave up after a year of making marbles. > Any tips on how I can get this into grass-6.4.0?

I have now added a page in the GRASS wiki to cover this, http://grass.osgeo.org/wiki/Blue_Marble feel free to improve. I've only downloaded the 2002 version + "Earth at Night" image, so 2004 next-generation info is a bit thin. But I think you can adjust the 2002 method to suit. I slightly copied the method from this old post: http://article.gmane.org/gmane.comp.linux.gps/1437/ If you want global topography + sea floor bathymetry elevations, see the instructions for getting the 1' global dataset: http://grass.osgeo.org/wiki/Marine_Science#Bathymetric_data http://topex.ucsd.edu/marine_topo/mar_topo.html enjoy, Hamish _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
