Abstract
ERTS imagery interpretation for synoptic environmental assessments has many practical advantages and some limitations. There is no typical ERTS signature for landslides because the spectral anomalies vary greatly with surface conditions. The low reflectance of open water bodies in the near-infrared bands is a good indicator of the extent of flooding. Background knowledge is important for both landslide detection and flood reconnaissance with ERTS imagery. The detection and delineation of flooding appear to have the greatest potential for operational applications of ERTS.Keywords
