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.
