[GRASS-user] r.sun problem

[dorothee spindelndreher]

Hi all.
 
I am using r.sun -s to calculate solarmaps for each month. I wrote a shell script which calculates every 10th day (including the shaddowing effect). But something is going wrong. I looks like the shaddows are displaced somehow (see attachement). Using r.sun2 -s didnt make any difference.
Curiously once it worked! But although I'm using the same projection, location, mapset and DSM - it doesnt work anymore.
 
I hope anybody could help me out or have any ideas how I could solve this problem....I really need these maps.
 
Thanks in advanced!
  
Regards
Doro
