Rocky Mountain Geographic Science Center [More info]: 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.
Seamless geographic data distribution system [More info]: Online map system providing downloadable geospatial data, primarily NSDI framework themes (that is, general geographic data such as transportation, boundaries, hydrography, orthoimagery, land cover, and elevation).
South Florida Information Access (SOFIA) data exchange [More info]: Provides links to the data, models and maps on the biology, ecology, geology, mapping, hydrology, and chemistry of research studies in southern Florida.
Spatial Data Transfer Standard (SDTS) information site [More info]: Homepage for ISGS Spatial Data Transfer Standard (SDTS) information with links to software, FTP site, standard, and data available on line, USGS mass conversion schedule, meetings, and related web sites.
Western Geographic Science Center [More info]: USGS geographic information studies and data for the western United States.
A New Method for Mapping Population Distribution [More info]: 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.
A rapid method for creating qualitative images indicative of thick oil emulsion on the ocean's surface from imaging spectrometer data [More info]: Technical details explaining how remotely sensed visible and infrared data can help recognize the extent of oil spills.
Advanced Remote Sensing Research [More info]: 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.
Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Overview [More info]: General characteristics and spatial resolution of imagery products available from this type of sensor.
Advanced Very High Resolution Radiometer (AVHRR) [More info]: Coverage, characteristics, and availability of AVHRR data from a broad-band scanner sensing in the visible, near-infrared, and thermal infrared portions of the electromagnetic spectrum.
