[GRASS5] NASA onearth WMS service used in GRASS

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.

Regards
Soeren

Thanks very much Sören. This will be useful.
