Reprocessamento digital das imagens SLAR geradas pelos Projetos RADAM e RADAMBRASIL, Projeto RADAM-D

Abstract

The Project RADAM (for Radar Amazon), organized in October 1970, was a Brazilian government decision to undertake a reconnaissance survey of the Amazon region and the adjacent Brazilian Northeast. The major objective was to collect information on mineral resources, soils, vegetation and land use. In June 1971, the first flights took place. In July 1975, the program was expanded to the hole country and had its name changed to RADAMBRASIL. The remote-sensing platform was a twin-jet Caravelle flying at an altitude of 12 km with a speed of approximately 690 km/h. On board was the side-looking radar Goodyear Mapping System 1000 (GEMS). The generated data are stored at CPRM-Geological Survey of Brazil. This RADAM-D Project deals with the preservation of original SLAR image negatives and diafilms through data scanning and digitization. The project works with the inventary of available material, organization of radar strips, high resolution image scanning, composition of final images and its publication
