Hello,
I’ve been use qgis for a while and I’m starting now with GRASS, too.
I’m interested in building a inter-visibility map using a point shapefile and a DEM. QGIS has a plugin for viewshed, and I tried LOS in GRASS which works wonderfully, for a single point of observation.
Is there a way to get lines linking sites that are visible from each other?
Thank you
