Geographic Analysis and Monitoring Program (GAM) conducts studies about land surface change, environmental and human health, fire and urban ecology, and natural hazards to help decision-makers in land-use planning and land management.
Clearinghouse for the description and availability of multiple geospatial datasets relating to Alaska from many federal, state and local cooperating agencies under the coordination of the Alaska Geographic Data Committee.
Home page for National Wetlands Research Center's (NWRC) Spatial Analysis Branch (SAB), which uses state-of-the-art technology to assist the work of natural resource managers with spatial data and computerized analysis techniques.
With the addition of elevation and land use and land cover data, we can show population density on a map much more effectively than if we simply color census areas. The resulting maps should allow better planning, especially in highly developed areas.
To expand data functionality and capabilities for users of The National Map of the U.S. Geological Survey, data sets for six watersheds and three urban areas were converted from the Best Practices vector data model formats to Semantic Web data formats.
New and experimental methods of analyzing geospatial imagery, including detailed spectral analysis of land surface materials, historical image analysis, and long wave infrared image analysis.
Website for the Columbia Environmental Research Center with links to staff, publications, databases, field stations, and projects including those on the Rio Grande, burrowing owls, sea turtles, and geospatial technology.
Web site for an Internet Map Service (IMS) serving base cartographic data, USGS data, science applications and real time modelling analyses for the Columbia River basin using geospatial analysis technology.
GIS data set from the USGS National Landslides Hazards Program showing major landslide events in the United States and Puerto Rico with metadata. Map layer can be downloaded in shapefile format or SDTS format.
Descriptions, results, and data on research projects using geographic analysis and monitoring and remote sensing to study ecosystems and land processes in the Arctic region.
Fact sheet describing the value of The National Map designed as a network of digital databases that will provide a consistent national geographic data framework in responding to natural hazards and human-induced disasters.
Complex geographic information can be analyzed with mathematical models to show us the spatial patterns of human building, vegetation growth, and other landscape characteristics that may result from environmental changes we may expect in the future.
A wide variety of web interfaces providing scientific information in geographic form for exploration and analysis, developed by this organization that focuses on geospatial analysis.
A software model for regional interpretation of water-quality monitoring data, estimating origin and fate of contaminants in streams, with documentation, publications and data for the applications.
Provides location-depth grids of bathymetry available for San Francisco Bay and tools for examining those grids. Data provided as GIS grids and animations.
Homepage describing The National Map, which will produce a seamless, continuously maintained set of public domain geographic base information, with links to map viewer, pilot projects, reports, fact sheets, and national atlas.
Methods and techniques used to collect and process LiDAR elevation data, the generation of the digital elevation model (DEM) and the 2-foot contours, and the quality-assurance procedures and results.
