Hi folk, I hardly never work with raster calculations, and unfortunately there is nowhere a collection of syntax examples for different use cases to be found (documentation :( ).
Anything apart from +-*/ is beyond my scope. So, I made a viewshed analysis over a digital surface model (try the awesome Visibility Analysis plugin form Zoran Čučković and buy him a beer!) A lot of "views" are caught by tree canopy, but I am only interest in the flat grounds. So I substracted the surface model layer from the ground model layer, and this is Layer 1. Giving a threshold of 1 meters difference for inaccuracities, all pixels in this layer above 1 should result in 0 (zero) in my viewshed raster (Layer 2) Please give me some hints, Cheers, Bernd <mailto:cont...@zoran-cuckovic.from.hr>
