'A GOOD, A BETTER OR THE BEST REMOTE SENSING APPLICATION SYSTEM' FOR TROPICAL RAIN FOREST SURVEY IN THE AMAZON REGION

摘要

A historical review based on personal experience is presented of forest surveys executed in the Amazon region. For this account two remote sensing application techniques were selected, using: trimetrogon aerial photograps (Brazil, 1942; scale 1.:40,000) and Side Looking Airborne Radar (Colombia, 1973; scale 1:40,000). Some remarks are made, regarding the latest types of satellite images. The conclusion is drawn that "a good, better or the best remote sensing system" depends on the object of the survey and the availability of field information. Keynotes in this account are: Remote Sensing, Tropical Rain Forest, Amazon Region.
