- Removed ETOPO2 digital elevation model and replaced it by the much more recent (and usually more detailed) Shuttle Radar Topography Mission (SRTM) data.

Resolution of the full dataset would be 1-3".

For offline mode we are using a 21600x10800 image.
- Changed the colorpalette to something more subtil and professional looking.

Please remove your old system marble directory before doing "make install".
