Hi,
I'm currently using pyGRETA to evaluate renewable potentials in several country but i'm having some problems with RoofTopPV. In particular in some country (for example Greece), i'm getting a potential near to zero which is obviously wrong. I saw that the problem is related to the masking of the available area, so i tried to check all the masking parameters and i found that the problem seems to lie in the settlement footprint matrix. In particular is like in Greece, pyGRETA does not see any settlement. For the input raster i downloaded the high resolution rasters (0.32 arcsec or 10m) of World settlement footprint from (https://figshare.com/articles/dataset/World_Settlement_Footprint_WSF_2015/10048412). Then i resampled them to 250 m using both the nearest neighbour and the mode algorithm and then i merged them in a unique file.
I attach the .mat file (converted in .txt) that pyGRETA generate for Greece, starting from the world raster of settlement footprints (Greece_settlemet.txt.
Have you possibly any idea on the error? maybe i'm doing something wrong with the pre processing of the rasters?
