How to call GDALDEMProcessing from the GDAL C# wrapper?

I'm trying to calculate aspect and hillshade in C# using GDAL. I have installed GDAL and GDAL.Native packages via NuGet but I could not find the GDALDEMProcessing() calls (https://gdal.org/programs/gdaldem.html) for calculating aspect and hillshade of DEM file. How to calculate aspect and hillshade in C# using GDAL?

Solution

  • You can use GDAL wrapper function : 

    Gdal.wrapper_GDALDEMProcessing(destRaster, srcRaster, "hillshade", null, null, null, null)

    (you can provide GDALDEMProcessingOptions as 5th parameter)
