[GRASSweb-list] Grass viewshed calculation

[Melisande Celis]

Hi,
 
I'm a student from the KU Leuven University in Belgium. Because of my thesis, I'm looking
for information about GRASS, but I couldn't find it on the website. Where can I find wich
algorithms the GRASS software uses for the calculation of viewsheds? (About how 
viewsheds are made by GRASS?)
 
Thank you! Kind regards,
 
Melisande Celis
