Features from Raster

The Features from Raster tool derives features such as streams and roadway embankments from an elevation raster.

Input Parameters

  • Input raster – Select the input elevation raster.
  • Feature type – Select the feature type to generate.
    • "Stream" – This option generates stream lines given the threshold area for stream generation.
    • "Ridge" – This option generates ridge lines for the inverted raster given the threshold area for ridge generation.
  • Threshold area – The threshold area to use for stream or ridge generation.
  • Pre-processing engine – Which pre-processing engine to use.
    • "Whitebox rho8" – Computes flow directions and accumulations using the Rho8 algorithm.
    • "Whitebox full workflow" – Computes flow directions and accumulations using the Whitebox tool full workflow algorithm that uses a standard D8 method for computing flow directions.

Output Parameters

  • Output coverage – The following interpolation methods are supported:
