Abstract
Remotely-sensed multiband imagery, covering 64 Km 2 between latitudes 18 ° 28′ 30″-18 ° 34′ 45″ N and longitudes 74 ° 20′-74 ° 23′ 15″ E, has been interpreted. The climate of the region studied is semi-arid tropical with an annual precipitation of 50 cm. The aerial photography, comprised of color infrared (CIR) and black-and-white infrared with 0.5 to 0.9 μm spectral band, and conventional panchromatic with 0.5 to 0.72 μm spectral band, was interpreted by conventional stereoscopic analysis based on tone, texture, pattern, shape, and size. The area was divided into 12 geomorphic units, confirmed from ground survey, and a soil map showing soil series associations was prepared and interpreted. The imagery was interpreted for the delineation of land use patterns. The I.R. false color and the black-and-white imagery on the scale of 1:25,000, with adequate ground surveys and checks, is useful for delineating second-order geomorphic units, soils at the level of association of series, and broad land-use classification.
