In the following sections each of these programs will be 
briefly described together with their latest realizations. 
Crop Survey 
This is probably the most important of the programs being 
developed in terms of the economic and sociaJ benefits that can be 
generated for the country. The purpose of the program is to develop a 
survey system for the major economic crops through the automatic processing 
of Landsat imagery. Planted area estimations for cultures of sugar cane, 
soybeans, corn and wheat have been obtained with success for areas no 
larger than 4 Landsat scenes. Presently a survey of sugar cane is being 
carried out for the entire State of Sao Paulo. The area of sugar cane in 
this state is covered by 14 Landsat scenes and it is responsible for about 
60% of the total national production.
