pyflwdir.dem.slope# pyflwdir.dem.slope(elevtn, nodata=-9999.0, latlon=False, transform=Affine(1.0, 0.0, 0.0, 0.0, -1.0, 0.0))[source]# Returns the local gradient Parameters: elevnt (1D array of float) – elevation raster nodata (float, optional) – nodata value, by default -9999.0 latlon (bool, optional) – True if WGS84 coordinates, by default False transform (affine transform) – Two dimensional transform for 2D linear mapping, by default gis_utils.IDENTITY Returns: slope Return type: 1D array of float
