[GRASS-user] Problems with r.viewshed

[Luis Miguel Royo Pérez]

I'm sorry but it didn't work.

I have reinstalled the addon but it didn't work, reinstalled GRASS 6.4 
and neither, then installed GRASS7 again, and appears this message:

r.viewshed -b input=Portada en inisig output=visPort 
coordinates=-3.74034324324,42.5352702703 obs_elev=9 tgt_elev=1.75 
max_dist=30000
Computing events...
Computing visibility...
r.viewshed: statusstructure.cpp:73: float
get_vertical_angle(Viewpoint, StatusNode, surface_type,
int): La declaración `fabs(sn.dist2vp) > 0.001' no se
cumple.


I will try in another PC.

Thank you for your time.
