pywasp.lincom.roughness_to_landmask(lc_map, lctable)[source]

Convert a roughness map to a landmask map

All classes with z0 = 0.0 will be converted to water (0) points, while all other roughness lengths will be considered land.

Warning

This function is experimental and its signature may change.

Parameters:
  • lc_map (xarray.DataArray) – Landcover rastermap

  • lctable (LandCoverTable) – Map from LandCoverID to roughnesses

Returns:

  • raster_mask (pw.RasterMap) – RasterMap of water (0) and land (1) mask

  • vector_mask (pw.VectorMap) – VectorMap of water (0) and land (1) mask
