Calculates surface model used in METRIC

Share:

Description

DEM map is used to generate the surface representation of the image through of aspect and slope maps. This procedure helps to avoid differences in the surface temperature (and finally Evapotranspiration) caused by different incidence angles and/or elevations in mountainous areas.

Usage

1
METRICtopo(DEM)

Arguments

DEM

raster with Digital elevation model
