A Research Agenda for Geographic Information Science at the by National Research Council, Division on Earth and Life

By National Research Council, Division on Earth and Life Studies, Board on Earth Sciences and Resources, Mapping Science Committee, Committee on Research Priorities for the USGS Center of Excellence for Geospatial Information Science

Complete and authoritative baseline geospatial info content material is essential to the country and to the U.S. Geological Survey (USGS). The USGS based its heart of Excellence for Geospatial details technology (CEGIS) in 2006 to strengthen and distribute nationwide geospatial information resources in a fast-moving details know-how setting. that allows you to satisfy this venture, the USGS requested the nationwide learn Council to evaluate present GIScience functions on the USGS, establish present and destiny wishes for GIScience functions, suggest ideas for strengthening those features and for participating with others to maximise study productiveness, and make innovations in regards to the preferable examine parts for CEGIS to pursue. With an preliminary specialize in enhancing the functions of The nationwide Map, the document recommends 3 precedence examine components for CEGIS: info entry and dissemination, facts integration, and information versions, and additional identifies study subject matters inside of those parts that CEGIS may still pursue. to deal with those examine themes, CEGIS wishes a sustainable examine administration strategy that consists of a portfolio of collaborative study that balances brief and long-term pursuits.

A map of the hiking trail for Mt. Katahdin, including streams, points of interest, and elevation profile), to requests for traditional topographic maps. To respond nimbly to such a range of information requests, The National Map has an intelligent spatiotemporal data model based on formal specification of geographic feature concepts in the form of ontologies. The National Map has an individual feature database as well as the more traditional layer databases associated with the original version.

As one indication of the GIScience capabilities already tapped by CEGIS, the projects funded in FY 2007 (excluding those funded through the bureau-wide call for proposals) focus on the following: • • • • • Automated data integration ($280,000) Generalization for The National Map ($190,000) Building an ontology for The National Map ($250,000) Multiresolution raster data for The National Map ($200,000) LIDAR-derived elevation technology assessment ($80,000) 20 A Research Agenda for GIScience at the USGS • • Elevation feature extraction ($127,000) Fractal and variogram analysis of scale and resolution effects in geospatial data ($100,000) Appendix D includes more information on each of these projects, and Chapter 3 describes how these projects fit with the committee’s suggested research topics.

Not solely within NGPO).
