Abstract : The objectives of this study were: 1) to study the feasibility to intrusive rock mapping and to establish criteria for regional geological mapping at the scale of 1:500,000 in polycyclic and polymetamorphic areas using Logic Method of photointerpretation of LANDSAT imagery and RADAR from RADAMBRASIL project. 2) to evaluate the spectral behavior of intrusive rocks, using the Interactive Multispherical Image Analysis System ( Image-100 ). The region of Campos (city) in northern Rio de Janeiro State was selected as the study area and digital imagery processing and pattern recognition techniques were applied. Various maps at the 1:250,000 scale were obtained to evaluate the results of automatic data processing. (Author)
