Hi everybody, after applying the visible count transform (TileViewshedTilesCountPar) to an image (with a height range from 0 to 143 m) and a point file (with around 200 observers) with a relative Z of 25 m, the resulting image has negative values.
This negative values seem to match the visibility area and a closer look to the image shows that you have negative values adjacent to positive ones (for instance there are negative values of -128 side by side with positive values of 127). It seems the absolute value is correct but the negative sign makes this result a strange one. Is this an expected behaviour?
(edited: I noticed when the number of observers is significantly reduced (around 100) the resulting image values remain positive. Is there a limitation for the number of observer points?)
If needed I can provide a link to the mxb.
