Hi, I have 2D isolines in GRASS vector format with elevation in an attribute field called height. I used v.surf.rst function to create raster DEM. However, after creation, it outputs a DEM with value 0 elevation only. The description of the function is given as below. What would be the possible cause for this? I am using wingrass 7.
cheers, Brian. v.surf.rst -z input=isoline@TOPOIKDATA zcolumn=height elev=elev_1m Reading features from vector map ... Ignoring 86730 points (too dense) Processing segments...
