Classification of land degradation identified by visual interpretation of spectral features and texture types ^*

Status of degraded land	Texture types	Spectral features
Slight	Smooth, fine, and coarse	High reflectance dominates, with linear and patchy features (homogeneous light-tone pattern)
Moderate	Mixed with fine and coarse and mottled	Moderate reflectance dominates with patchwork type features (associations of patches of light to moderately dark gray-tones, rounded or oval, isolated or connected)
Moderate to severe	Fine, coarse, mixed, mottled, rounded, subdued (blurred), rugged, and peaked divided	Moderate to low reflectance dominates, with patchwork type features (mosaic of intermingled patches of light and dark grey-tones, isolated or partially connected patches)
Severe	Fine, coarse, rough, and peaked divided	Low reflectance dominates with patchy-punctuated features (irregular, rounded or oval, and mostly isolated patches)
