Abstract:

Rapid proliferation of Vinal, a tree found in the Gran Chaco region of Argentina, impacts both the economy and ecology of Formosa Province. Landsat-GEOPIC digital imagery, combined with effective ground sampling surveys, provided new information on the occurrence and distribution of Vinal in a cost and time effective manner. Changes in extent and distribution of vinal over a 6,822 sq km study area were analyzed using 1975 and 1980 Landsat data and digital change analyses in the EarthSat GEOPIC Interact system. Results indicate a seven to ten percent annual area increase of Vinal. Landsat GEOPIC processing was used to generate images and distribution land cover and change analysis maps at 1100,000 scale.
