This tool calculates the maximum length of the flowpaths that run through each grid cell (in map horizontal units) in an input digital elevation model (dem
). The tool works by first calculating the D8 flow pointer (d8_pointer) from the input DEM. The DEM must be depressionless and should have been pre-processed using the breach_depressions_least_cost or fill_depressions tool. The user must also specify the name of output raster (output
).
