> Dear developers,
> because i was realy impressed by the NASA tool "World Wind", i was thinking
> about to use the data, provided
> by the NASA, direct in GRASS.
> 
> So i have written a small script (r.in.onearth), which imports NASA satellite
> images of the following types:
> 
> * WMS Global Mosaic, a High Resolution, Global Coverage, Landsat TM 7 mosaic.
> All bands!
> * Radar reflectance images produced by the SRTM mission.
> * Blue Marble Next Generation layer, one for each month of the year.
> * Composite of data produced by the MODIS Rapid Response System, from data
> collected yesterday by the MODIS/Terra and MODIS/Aqua.
> 
> To get the data into GRASS, r.in.onearth is downloading the data as geotiff
> images via wget from the NASA WMS server in the size and resolution
> of the current GRASS location, and imports them via r.in.gdal into GRASS.
> The script works fine, but sometimes the NASA server cannot provide the
> MODIS-satellite images.
> 
> At my homepage is a tar.gz, called r.in.onearth.tar.gz, which includes the
> shell-script r.in.onearth, small documentation and a Makefile.
> My homepage: http://www-pool.math.tu-berlin.de/~soeren/grass/modules/
> 
> The programm needs "wget" and a Lat/Long location EPSG:4326 to work (Lat/Long
> wgs84 projection).
> There are two versions of the script, one wich needs a g.region patch which
> is, many thanks to Markus, already in CVS and
> a second which dont need that patch.
> 
> If there are other WMS server wich provide geotiffs in EPSG:4326 projection,
> so let me know. I will try to add them to the script.
> 
> It would be nice if somebody can test the script and report bugs, hints and so
> on.
> 
> Enjoy.
