Satellites to play expanded role in water resource studies


  • Anonymous


The importance of remote sensing—examining earth's resources with airborne and satellite cameras and other devices—is bound to expand in the study, development, and protection of our water resources, according to Joseph S. Cragwall, Jr., Associate Director, U.S. Geological Survey, opening the Fifth Annual William T. Pecora Memorial Symposium on Remote Sensing.

The symposium was held June 10–15, 1979, in Sioux Falls, South Dakota. Cragwall, formerly the USGS chief hydrologist, noted that satellites equipped with sophisticated electronic devices have provided scientists with a large amount of hydrologic information that could not otherwise be collected.
