Remote sensing data types include medium spatial resolution multispectral (MRMS), high spatial resolution multispectral (HRMS), hyperspectral, aerial and acoustic. Calibration and validation data types include spot
check, transect, video and other (local knowledge, aerial photographs and undefined). Processing types include supervised classification, unsupervised classification, spectral analysis and radiative transfer modeling
(spectral+radiative), manual delineation, and other
