Dear Niels, Debian is a bit far away in the GRASS versioning. Additionally, i.albedo is included only in the version 7, which is a development version available on svn.
You could do this if you feel up to it: Step 1: get grass gis svn version ---------------------------------------- cd /home/niels (assuming this is your user place) mkdir dev cd dev svn checkout https://svn.osgeo.org/grass/grass/trunk grass_trunk cd grass_trunk there, copy the attached c7.sh file. Step 2: Get Debian up it the requirements ------------------------------------------------- run the script install_grass_debian.txt by typing "sh install_grass_debian.txt" where you saved it in your computer Step 3: Compile GRASS ---------------------------- cd /home/niels/dev/grass_trunk sh c7.sh make make install (this requires you to have root access) Step 4: Run grass experimental version ----------------------------------------------- type "grass70" any help on that please dont hesitate. many good wishes and good luck, Yann 2008/10/2 Niels Thevs <[EMAIL PROTECTED]>: > Dear Yann chemin, > > have many thanks for your detailed reply. > > Currently, I have GRASS 6.2 in an Debian Environment.
