> What is the size and x-y resolution of your mapset? nsres: 86.08807728 ewres: 86.08807728 rows: 3793 cols: 3719 cells: 14106167
> Try adjusting the cell sizes so that you have > integer cell extents. r.cva works in this mapset when set to 'random' but not 'sites' type of analysis. Would the cell extents still be the problem? Below are the terminal outputs for three runs using the same the dem file. In the first run I used a binary raster map to define 1 viewpoint for a 'sites' analysis and got a segfault. In the second run I used a vector map to define 1 viewpoint for a 'sites' analysis and got a segfault. The third run was set to 'random' with a sample frequency designed to produce one viewpoint. This run completed successfully.
