GRASS module r.los crashes (using the QGIS GRASS interface), giving this:

r.los input=elevation.10m@PERMANENT coordinate=602085.704,,4927029.641 obs_elev=1.75 max_dist=5000 output=LOS_elev

Using maximum distance from the viewing point (meters): 5000.000000

Module crashed or killed

I have tried multiple iterations with the same result.


#1 Updated by Jürgen Fischer over 9 years ago

  • Target version changed from Version 2.2 to Future Release - Lower Priority

#2 Updated by Markus Neteler over 8 years ago

FWIW: In GRASS GIS 7, r.los has been retired and replaced by the very fast r.viewshed. The flags and parameters are rather identical.

#3 Updated by Radim Blazek almost 8 years ago

  • Resolution set to worksforme
  • Status changed from Open to Closed

r.los with GRASSS 6.4 works for me in QGIS 2.12, in GRASS 7 there is r.viewshed. Most probably the module itself was crashing regardless of QGIS. If the problem persists, try to run the same command from GRASS shell, if it crashes also in GRASS shell, please report in GRASS bug tracker, if it happens only in QGIS, please reopen this issue.
