DOWNLOAD EBOOKComprehensive 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.

DOWNLOAD EBOOKIn response to the need and an intergovernmental commission for a high resolution and data-derived global ecosystem map, land surface elements of global ecological pattern were characterized in an ecophysiographic stratification of the planet. The stratification produced 3,923 terrestrial ecological land units (ELUs) at a base resolution of 250 meters. The ELUs were derived from data on land surface features in a three step approach. The first step involved acquiring or developing four global raster datalayers representing the primary components of ecosystem structure: bioclimate, landform, lithology, and land cover. These datasets generally represent the most accurate, current, globally comprehensive, and finest spatial and thematic resolution data available for each of the four inputs. The second step involved a spatial combination of the four inputs into a single, new integrated raster dataset where every cell represents a combination of values from the bioclimate, landforms, lithology, and land cover datalayers. This foundational global raster datalayer, called ecological facets (EFs), contains 47,650 unique combinations of the four inputs. The third step involved an aggregation of the EFs into the 3,923 ELUs. This subdivision of the Earth's surface into relatively fine, ecological land areas is designed to be useful for various types of ecosystem research and management applications, including assessments of climate change impacts to ecosystems, economic and non-economic valuation of ecosystem services, and conservation planning.
