Development of earth resources survey techniques at GSFC: Overview

Earth resources survey and remote sensing techniques under development at GSFC are reviewed. Emphasis is focussed primarily on: (1) definition and demonstration of remote sensing techniques which lead to the measurements of physical quantities from which earth resources related parameters can be determined; (2) development of sensors, spacecraft, and on-board as well as ground based data management systems; (3) determination of earth resources related parameters from the remote sensing observations and measurements; and (4) applications of earth observations to resource management.
