Abstract
Landsat images provide a great amount of valuable information that, when complemented with information from other sources, can be organized in a way that it is useful for decision making in agricultural planning. This organization is formalized by means of a geographical data hase whose components are described in this paper. They include acquisition of information and its insertion into the data base, the storage requirements, the logical structure which is basically relational, geoprocessing and applications. Answers to queries can be graphics displayed through the Ramtek system using two T.V. terminals or printed on an APL terminal or a fast printer. This data base is currently being used in several projects carried jointly with government institutions.
