San Francisco Bay Area ACM SIGGRAPH Digital Cartography Computerized Map-Making Barry Napier USGS, National Mapping Division January 26, 1988 8:00 PM XEROX Palo Alto Research Center Auditorium 3333 Coyote Hill Road, Palo Alto Maps, perhaps the earliest form of graphics, are undergoing a revolution due to computer. From the collection of data using digitized aerial photos and positions using satellites to the output on laser printers and CRTs, all areas have been affected. Simulated landscapes, as in the video "LA, The Movie," are generated by combining Digital Elevation Models (DEM) and LANDSAT satellite data. Separate layers of information are combined to help researchers predict where and when landslides will occur. Land Use and Land Cover (LULC) maps are used for making public policy decisions. Many cities are converting and combining their old maps of above and below ground services into one system. U.S. Geological Survey (USGS) is currently converting its map library collection (over 55,000 maps for just the 1:24,000 series alone) from paper form to digital. In addition they are defining digital map standards to improve communication and resource sharing between organization. Barry Napier will describe the current conversion process and what research is being explored. Information about what digital data can be ordered now will be available. Barry Napier is a Cartographer with USGS National Mapping Division. He has been with USGS for 6 years and received his BS in Geography from Berkeley. He is a member of Bay Area Automated Mapping Association (BAAMA) and American Congress on Surveying and Mapping and is also the president of the local chapter of the American Society for Photogrammetry and Remoting Sensing.
