Resumen

A Map of the Vegetation of South America Based on Satellite lmagery / Thomas A. Stone, Peter Schlesinger, Richard A. Houghton, and George M. Woodwell / The Woods Hole Research Center, P.O. Box 296, Woods Hole, MA 02543 / Photogrammetric Engineering & Remote Sensing / Vol. 60, No. 5, May 1994, pp. 541-551. / Abstract / We have developed a map of the land cover of South America based largely on NOAAAVHRRttC (Local Area Coverage) 1-km resolution data. Areas of South America for which there werc no LAC data due to cloud cover or other reasons were supplemented with a 3-year fi'me series of 15-km resolution NOAA AVHRR CVI data. Thirty-nine classes were labeled using existing vegetation maps, from phenology, and by visual interpretation of imagery. / We estimated that nine percent of the closed tropical moist forests of South America had been cleared in the decade prior to 1988, the date of the imagery; 22 percent of the original closed forests, which include tropical moist forests as a major component, of South America had been cleared or degraded; 18 percent of the original woodland and 25 percent of the grasslands had been cleared or degraded.
