Comprehensive and authoritative baseline geospatial data content is crucial to the nation and to the U.S. Geological Survey (USGS). The USGS founded its Center of Excellence for Geospatial Information Science (CEGIS) in 2006 to develop and distribute national geospatial data assets in a fast-moving information technology environment. In order to fulfill this mission, the USGS asked the National Research Council to assess current GIScience capabilities at the USGS, identify current and future needs for GIScience capabilities, recommend strategies for strengthening these capabilities and for collaborating with others to maximize research productivity, and make recommendations regarding the most effective research areas for CEGIS to pursue. With an initial focus on improving the capabilities of The National Map, the report recommends three priority research areas for CEGIS: information access and dissemination, data integration, and data models, and further identifies research topics within these areas that CEGIS should pursue. To address these research topics, CEGIS needs a sustainable research management process that involves a portfolio of collaborative research that balances short and long term goals.
