Description
Combination of NIR, SWIR1 and SWIR2 MODIS bands. SASI emulates the general shape of this part of the spectrum. To accomplish this, we evaluate a triangle with vertices at R(NIR), R(SWIR1) and R(SWIR2), where R is the reflectance at broad bands of the NIR, SWIR1 and SWIR2.
Usage
1
SASImodis(NIR, SWIR, SWIR2)
Arguments
NIR
Raster of near infrared band from MODIS
SWIR
Raster of SWIR 1 band from MODIS
SWIR2
Raster of SWIR 2 band from MODIS
Value
Shortwave Angle Slope Index for MODIS
