'''i.uslek''' creates USLE K factor (soil erodibility) from sand, clay, silt fractions and organic matter fraction. Based on USDA 1951 (p209) quoted in FAO World Soil CD, and from some generic [soil class+OM] to K conversion table.
 
 
 
'''i.usler''' calculate the USLE erosivity factor of precipitations, 4 equations are available.
 
 
 
'''i.albedo''' creates Albedo. This module takes Modis, Aster, Landsat or AVHRR individual surface reflectance bands to calculate Albedo. This module is a precursor to r.sun or any Energy-Balance related processing.r.albedo
 
 
 
'''i.emissivity''' calculate emissivity from NDVI.
 
 
 
'''i.eb.*''' 10+ modules of Energy Balance related processing according to SEBAL model (Bastiaanssen, 1995).
 
 
 
'''i.vi''' Vegetation indices (13), single CPU (Baburao Kamble prepared the functions). MPI and grid versions prepared by Shamim Akhter
