SCIENCE APPLICATIONS INTERNATIONAL CORP. (SAIC) WILL MAKE DIGITAL MAPS FOR USGS

 MENLO PARK, Calif., Sept. 13 /PRNewswire/ -- As part of an expanded partnership with private industry, the U.S. Geological Survey, Department of the Interior, has contracted with SAIC's Melbourne, Fla., office which specializes in photogrammetric and Geographical Information System (GIS) applications. Two firms will be supporting SAIC as major subcontractors: JFK of Melbourne, and Intera Technologies Ltd. of Ottawa, Canada.
 The contract signed Sept. 1, in Menlo Park, is one of a series of awards that the USGS will make to mapping firms that meet established federal guidelines.
 Digital orthophoto quads, or DOQs are digital images of aerial photographs that combine the image characteristics of a photograph with the geometric qualities of a map. Because orthophoto technology removes displacements caused by camera orientation angles and differences in the terrain, the resultant image represents terrain features in their true geographic positions. The DOQs are produced in quarter-quadrangle coverages, which means that each DOQ covers one-fourth the area depicted on a standard, USGS 7.5-minute topographic map.
 DOQs are used by planners, engineers and government agencies to update changes in land use, transportation and utility corridors. The DOQs also can be used to analyze vegetation patterns, manage timber resources, assess wildlife habitats, delineate floodplains, and identify areas of potential soil erosion.
 The USGS's National Mapping Division developed DOQ technology at its Menlo Park center, beginning in 1987. In 1991 and 1992 the USGS awarded two smaller contracts that have served as prototypes for the SAIC contract. As part of the agreement, the USGS will continue to monitor the work of the production contractors in order to ensure quality control over the finished products and to assure they meet all U.S. National Map Accuracy Standards.
 "The demand for digital map data has grown tremendously and is now much greater than we can meet in a timely manner," according to Allen H. Watkins, chief of the USGS National Mapping Division, in Reston, Va. "Contracting makes sense. It helps us get the job done and it helps our customers."
 John R. Swinnerton, chief of the USGS mapping center in Menlo Park, said selection of SAIC was accomplished under provisions of Public Law 92-582, known as "The Brooks Act," which governs the selection of professional architectural and engineering services for government projects.
 Upon completion of the DOQs, SAIC will deliver them to the USGS. The USGS will then archive them and make them available in computer- readable formats, from its cartographic database distribution center in Reston, Va. A DOQ user guide is being developed by the USGS to provide more information to interested parties.
 A fact sheet relating to DOQs is available from the USGS Earth Science Information Centers in Anchorage, Alaska (907-786-7011); Lakewood, Colo. (303-236-5829); Menlo Park (415-329-4309); Denver (303-236-7477); Reston (703-648-4106); Rolla, Mo. (314-341-0851); Salt Lake City (801-524-5652); Sioux Falls, S.D. (605-594-6151); Spokane, Wash. (509-353-2524); Stennis Space Center, Miss. (601-353-2524) and Washington, D.C. (202-208-4047).
