Web-based U.S. gravity data system planned



A concerted effort is underway to prepare a substantially upgraded digital gravity anomaly data base for the United States, and to make this data set and associated usage tools available on the Internet. This joint effort, spearheaded by the geophysics groups at the National Imagery and Mapping Agency (NIMA), the University of Texas at El Paso, the U.S. Geological Survey (USGS),and the National Oceanic and Atmospheric Administration (NOAA), is an outgrowth of the new geoscientific community initiative called Geoinformatics (www. geoinformaticsnetwork.org). This dominantly geospatial initiative reflects Earth scientists' realization that existing information systems and techniques are inadequate for addressing many complex scientific and societal issues.
