|Abstract: Although coastal engineers have taken great strides in understanding and quantifying the complex coastal phenomena of the coastal zone, we are hampered severely by a lack of basic information of the coastal wave and current climate and a lack of understanding of the coastal processes of most of the coastlines of the world. Even the processes governing changes in the waters adjacent to our major cities are only modestly understood. The basic reason for this is a lack of "tools" or techniques to make measurements in the coastal zone. A new concept in data gathering has been generated using earth satellites. These satellites may observe areas of the coast and adjacent seas during times when other methods of sensing would be very difficult or essentially impossible. This paper describes the unmanned Earth Resources Technology Satellite (ERTS) which will be in orbit in 1972 and also the manned Skylab Satellite which will be in operation shortly thereafter. We are particularly interested in exploring possible international cooperation using the ERTS and subsequent satellites in coastal engineering and coastal processes with qualified investigators, by providing satellite imagery of desired locations over an extended period of time and by exchanging technical evaluations of satellite imagery developed in research programs in this country. In the ERTS data, resolving power will be in the range of 80 meters and so will be suitable for generalized information or gross coastal process. Subsequent satellites are expected to have greatly enhanced capabilities.
