One of the most significant environmental impacts of iron-ore mining is associated with landscape modifications, particularly in equatorial forest conditions around the N1-deposit located in the Carajás Mineral Province. The use of remote sensing data can be an excellent alternative to decrease costs for environmental data acquisition in this region. Integrated optical and radar images were used to extract complementary information about the landscape's natural conditions and anthropogenic changes in a prospective vision of future use impacts. The main objective of this research is to obtain a set of environmental data for future implementation of a knowledge-system which can be of common use to other areas or regions with similar characteristics.
