wbt_normalized_difference_index {whitebox} | R Documentation |
Calculate a normalized-difference index (NDI) from two bands of multispectral image data.
wbt_normalized_difference_index( input1, input2, output, clip = 0, correction = 0, wd = NULL, verbose_mode = FALSE )
input1 |
Input image 1 (e.g. near-infrared band). |
input2 |
Input image 2 (e.g. red band). |
output |
Output raster file. |
clip |
Optional amount to clip the distribution tails by, in percent. |
correction |
Optional adjustment value (e.g. 1, or 0.16 for the optimal soil adjusted vegetation index, OSAVI). |
wd |
Changes the working directory. |
verbose_mode |
Sets verbose mode. If verbose mode is False, tools will not print output messages. |
Returns the tool text outputs.
