Digital processing techniques and film density calibration for printing image data Digital processing techniques and film density calibration for printing image data

Satellite image data that cover a wide range of environments are being used to make prints that represent a map type product. If a wide distribution of these products is desired, they are printed using lithographic rather than photographic procedures to reduce the cost per print. Problems are encountered in the photo lab if the film products to be used for lithographic printing have the...

Overview of the land analysis system (LAS) Overview of the land analysis system (LAS)

The Land Analysis System (LAS) is a fully integrated digital analysis system designed to support remote sensing, image processing, and geographic information systems research. LAS is being developed through a cooperative effort between the National Aeronautics and Space Administration Goddard Space Flight Center and the U. S. Geological Survey Earth Resources Observation Systems (EROS)...

The use of the National Water Data Exchange in support of estuarine and coastal programs The use of the National Water Data Exchange in support of estuarine and coastal programs

The National Water Data Exchange(NAWDEX) was established by the U.S. Geological Survey in 1976. Its program is directed toward improving the exchange of water and water-related data collected and made available by hundreds of federal and non-federal agencies throughout the United States. This paper describes the NAWDEX program and the services which can be provided to assist coastal and...

The physics of debris flows — A conceptual assessment The physics of debris flows — A conceptual assessment

Debris flows exhibit conspicuous dynamic interactions among their solid and fluid constituents. Key features of the interactions are neglected in traditional theories that treat debris flows as viscoplastic continua or as uniformly dispersed grain flows, but improved understanding of grain-grain and fluid-grain interactions has emerged from recent experimental and theoretical research...
