The Amazon region has always been known for its legendry, histories and fantasies, which by their own reality. Now widespread-concepts and ideas for an area of more than 4,000,000 km2. -diffused image is an attractive and mysterious region, enhanced and disputed as granary of the world and hell green. The famous hileia of Humbolt hatch actually a extraordinaria diversity of physiognomies in all its extension.

.In this immense Continent "green" we observed the presence of plains, plateaus at various levels, unstable areas in opposition to areas stable, atapetados soils of different types, since the more acids to high potentiality. The soils of the Amazon, influenced by a large number of types of climate, favored the development of physiognomies, highly complex and diversified in their different forest ecosystems, cerrado formations, pioneer, areas of tension ecological, All these landscapes based-if a geology yet to discover their mineral deposits, so well kept.

Their complex network of drainage participates actively this dynamic exchange between the forces of nature, as the cause and effect of different phenomena.

.The creation of the Project RADAMBRASIL in 1970 aims at updating and systematization of the data on the Brazilian Amazon region with the aim of orienting more rational their occupation and exploitation.

At this time had already been developed the radar system of endorsed lateral, among other advantages, presented the ability to penetrate rain clouds and fine where constituted obstacles to the acquisition of aerial photos of large areas of the Amazon Region.

.Approved the choice of system, began the flights overcoating in July 1971 and the end of 1978 have already published 18 volumes in 117 thematic maps in the scale of 1:1,000,000 dealing geology, soils, aptitude agricultural, fitoecologia, geomorphology, potential use of land and subsidies to planning, in addition to 285 letters planimétricas and images of radar system with slots estereoscópicas.
