[Qgis-user] Angle of view

[Surya Jarausch]

Dear Qgis-Users,

I am relatively new to Qgis and working on a project to georeference
webcam-images and then determine the areas covered with snow.

To get an estimation of the quality of the projection, I would like to
create a raster with the values of the angle of view from a certain point –
the camera position. If the angle is near 90° the projection is likely to
be accurate, the more it becomes an pointed angle, the bigger possible
errors will get.

I already created a viewshed to determine the visible areas of the DEM.



I would be grateful if you could help me out,

Surya.
