I've a question concerning the import of raster maps into grass:
On http://www.riverthreat.net/data.html it is possible to get
worldwide data on river threats and environmental pressures. The data
are provided either as images (png), ascii files or Google-Earth KLM files
with a resolution of 30 seconds (0.5 degrees).
I'd like to import some of these maps into grass gis for further analysis. Thus some questions arise:
*Which coordinate system do I have to select so that the data are displayed correctly?
* What is the best data format for the import? I think maybe Ascii? These files have a header like following:
Maybe you can help me with the import!
Thank you very much
