Calculating Sloped Areas


I am trying to calculate areas in a sloped terrain. I am approaching the scripts with DEM and AreaCalculator Transformer with Type: Sloped Area. If I converted the DEM to polygons using RasterCellCorcer using 3D Forcer Transformer to have the z on the polygons, they still horizontal, thu I got the same area as the plane area. Any ideas how to calculate sloped areas with a DEM?

Hi @jaircasti, you can transform the DEM raster to a new numeric raster whose cell values represent the slope value at their location.

Another option would be to create a TIN out of the DEM first and then use the AreaCalculator
