Directional Roughness

The Landuse Raster to Directional Roughness tool converts a landuse raster (NLCD, C-CAP, etc.) to a coastal directional roughness dataset. The tool has the following options:

  • Input landuse raster – Select which landuse raster in the project will be the input.
  • Method – Select which method will be used for computation of the conversion.
    • "Linear" – Computations will convert in a linear fashion.
    • "Sector" – Computations will convert through the use of sectors.
  • Total distance – Sets the total distance of the directional roughness, measured in the units that the project is set in.
  • Weighted distance – Sets the weighted distance of the directional roughness, measured in the units that the project is set in.
  • Target grid – Select which grid will be the target.
  • Landuse raster type – Select which type the landuse raster is.
    • "NLCD" – Sets the landuse raster type to National Land Cover Dataset (NLCD). A mapping table file for NLCD can be found here and down below.
    • "C-CAP" – Sets the landuse raster type to Coastal Change Analysis Program (C-CAP). A mapping table file for C-CAP can be found here and down below.
    • "Other" – Sets the landuse raster type to be set by the user. This selection adds an option to the dialog.
      • Landuse to directional roughness mapping table – The Select File... button allows a table file to be selected. Its full file name will appear on the box to its right.
  • Default wind reduction value – Set the default level of wind reduction for the new dataset.
  • Output wind reduction dataset – Enter the name for the new wind reduction dataset
