[GRASS-user] importing L1G-data into GRASS

[Niels Thevs]

Dear Irene,

when you display one channel in GRASS, it is displayed by default with a 
color scheme ranging form green to yellow or blue to red. Under Raster 
-> Manage Map Color you can change this.

Regarding the import of Landsat images I prefer the following way, 
though not purely with open source software: Import your image with 
ERDAS and save it as img-file. img is a rather wide spread satellite 
image data format, which can be read inmediately by ERDAS, ENFI, ARC GIS 
etc. And, img.-files can be imported without any problems into GRASS. 
You even can build your location with a few clicks using an img file.

I guess that in Potsdam there is an ERDAS Licence somewhere.

Best regards

Niels
