ABSTRACT 
According to the requirement of the Consejo Federal de Inversiones (Federal Investment Council) and 
through the Centro de Sensores Remotos (Remote Sensing Center) depending on the Air Force, 
information was collected referring to the forest and other associated resources in the province of 
Tucuman environment. The province of Tucuman exhibits a great variety of geographic landscapes 
ranging from heights to depressed plain. Intensive agricultural developments prevail on the Piedmont 
zone and extensive agriculture-livestock on the plain. Floristic elements constituting the Tucuman forest 
are found on the mountain slopes; they make up mixed heterogeneous communities on the basis and they 
become homogeneous at a 1,900 meters height. In order to obtain a greater precision in image 
interpretation, the data were processed digitally (Contrast and edge enhancement) at the 1:130,000 scale. 
For composite color images a combination of bands 3,5 and 4 was used, with blue, green and red filters 
respectively. The results obtained were thematic maps, and the classes corresponding to native forest 
(Chaco Forest, Transition Forest, Mountain Forest), Woodland Shrublike Vegetation, Heights Pastures, 
Sugar Cane, Reforestation's and Citrus Fruits were found. Classes were quantified using a digitalizing 
table integrated to the IBM PC Analysis System, high resolution RGB Monitor.
