Hi all.
Surprisingly, reading a slite raster is way faster than a plain TIFF. Try this:
in QGIS, questa http://download.gfoss.it/TrueMarble/TrueMarble-250m.sqlite
and this:
http://ueod-globe.net/globe/TrueMarble_GeoTIFF/TrueMarble.250m.21600x21600.D2.tif.gz
Caution: you'll need gfdal 1.7, and probably a 64 bit system, as the sqlite file is >
2 Gb.
All the best.
