We already have a code published here that could generate random points inside an irregular raster boundary using R. If you want another option, below is an R code toContinue readingGenerate Random Points Inside Irregular Raster Boundary Using R Code

R-Code to Map the Area Under the Curve From Reflectance Values Using Multispectral Satellite Image

By EAL Salas on February 9, 2023February 9, 2023

You must read the multispectral image data into R, extract the reflectance values for a particular band, perform a calculation on each pixel and map the results, then save theContinue readingR-Code to Map the Area Under the Curve From Reflectance Values Using Multispectral Satellite Image

Error: At least one of the class levels is not a valid R variable name; This will cause errors when class probabilities are generated because the variables names will be converted..

By EAL Salas on February 8, 2023February 15, 2023

The error message indicates that one or more of the levels in the class variable are not valid R variable names. When using R, variable names must start with aContinue readingError: At least one of the class levels is not a valid R variable name; This will cause errors when class probabilities are generated because the variables names will be converted..
