Topographic correction
WebATCOR is a method for atmospheric and topographic correction of remotely sensed optical imagery covering the solar spectral region (0.4-2.5 µm) and thermal region (8-14 µm), German patent P4102579 granted 1993. It employs a database with the results of radiative transfer calculations based on the MODTRAN-4 code. WebTopographic Map of North Carolina.
