Whenever I try to make a viewshed analysis with only one point of interest, I get error messages. Is this because my Terrain model (GeoTIFF) is in ETRS UTM33 (EPSG: 28533)? I create a pointshape with on point and then execute "Create Viewpoints", adjust setting and afterwards I start the tool "viewshed". These are my first approaches, so I presume I am failing here big time, but the protocol is a riddle for me...

Here a snip of the protocol
