Abstract: The present space research emphasis on earth resources and environmental monitoring has potential benefits for the mapping, planning, and ocean engineering professions. Mapping at scales of 1:500,000 and smaller, with accuracies satisfying national maps accuracy standards from LANDSAT-l is performed routinely. Similar quality urban maps have been compiled from LANDSAT-1 at a scale of 1:250,000. Regional land use maps of nine basic categories with over 90% classification accuracies are routinely prepared in the United States, and classifications of up to 34 different land-use types with 85% accuracies have been achieved in certain nonurban areas. Several high altitude aircraft flights are demonstrating the possibility of future spacecraft carrying a microwave (radar) payload for monitoring global sea states.
