In R
, there are landsat
package (CRAN)
landsat provides basic tools for working with satellite imagery such as automated georeferencing and cloud detection. It contains functions
for radiometric normalization, and several different approaches to atmospheric correction.
Four topographic correction algorithms have been implemented. Other useful functions such as bare soil line and tasseled cap calculations have been included. While these functions were developed with Landsat data in mind, they are suitable for use with satellite imagery from
other platforms as long as appropriate calibration data are used.
