I want to draw several lines between pixels under some creteria :


  • First Criteria : The distance between 2 pixel is under 2000m and upper than 500m

  • Second Criteria : The absolute difference of Z value is under 600m and upper than 400m

I tested to convert my raster DEM to points then apply this creteria but it takes a lot of time. Have you any proposal or suggestions? I'm using GRASS, Postgis or Python
