This film shows how the Earth Resources Technology Satellite helped meet the need to provide a worldwide survey of earth resources to help scientists and governments plan their use and conservation. U.S. scientific investigators explain how they were using ERTS (later renamed Landsat) images to identify crops, forests, and grass lands, study urban development, determine the boundary of wetlands, identify geological features that may lead to mineral and fuel deposits, and monitor disasters including volcanic eruptions and floods.
