RESUMO

The objective of Project Rondônia is the determination of patterns of automatic classification of intrusive granites belonging to the tin-bearing region of Rondônia and localized throughout nearly the totality of the Federal Territory of Rondônia. This project utilized LANDSAT multispectral imagery, copied on paper and on magnetic tapes (CCT-computer compatible tape). Initially, a photogeological map corresponding to half of the referred territory was constructed at a scale of 1:1.000.000. The final map situates spatially and chronologically granites with cassiteritic (tin-ore) mineralizations. In this stage, a test area was proposed wich encompasses the granitic complex of Massangana/São Domingos. Mapping would be carried out by conventional photogeologic interpretation at a scale of 1:250.000 and preceeded by automatic interpretation and processing through the IMAGE-100 multispectral analyzer system. Programas used during automatic interpretation included "slicer" and "cluster synthesis" algorithms.
