sm_inversion_lut: Inversion of SM from look up table generated by WCM

In WCM: Water Cloud Model (WCM) for the Simulation of Leaf Area Index (LAI) and Soil Moisture (SM) from Microwave Backscattering

Description

Inversion of SM from look up table generated by WCM

Usage

sm_inversion_lut(img, lookuptable)

Arguments

img	raster object
lookuptable	Look up table simulated from 'wcm_sim' function

Value

a raster object (pixel value represents SM)

Examples

radar1 <- raster::raster(ncol=10, nrow=10)
val <- seq(-12,-7, length.out=100)
radar1[] <- val
A= -9.596695
B= -0.005331
C= -11.758309
D=  0.011344
lut1 <- lut_wcm(LAI=seq(1,6,0.1), SM=seq(0,.6,.01),coeff=c(A,B,C,D))
example(out_sm <- sm_inversion_lut(img = radar1,lookuptable = lut1))

Example output

Warning message:
In example(out_sm <- sm_inversion_lut(img = radar1, lookuptable = lut1)) :
  no help found for ‘out_sm <- sm_inversion_lut(img = radar1, lookuptable = lut1)’
