Computer software that allows geospatially referenced data to be linked to geographic features. Use this term only for information that is about GIS and not for the use of GIS in applications and projects.
Website with links to USGS hydrologic, geohydrologic, soil, and geologic projects in Missouri using geographic information systems (GIS) technology with digital datasets of images, models, and maps produced by the projects to view.
Access to downloadable GIS databases including the Global Digital Elevation Model (DEM), remotely sensed products, data on world energy and mineral deposits, biodiversity, and geologic hazards for use with ArcView or free software.
Digital data sets describing the Arbuckle Simpson aquifer and surrounding areas in Carter, Coal, Johnston, Murray, and Ponotoc Counties in Oklahoma. The data are in shapefile format to create maps for many uses.
Access to public web map services and interfaces developed at the EROS Data Center searchable by keywords and categories with interactive maps, viewer templates, information sheets and latest news items and updates on geospatial products.
Planetary Interactive G.I.S.-on-the-Web Analyzable Database (PIGWALD), an interface to support and integrate Geographic Information Systems (GIS) graphical, statistical, and spatial relational tools for analyses of planetary datasets.
This report consists of materials prepared for a GIS spatial analysis course intended for instructors preparing spatial-modeling training and scientists with advanced GIS expertise. Downloads available in many formats (PDF, ArcView, Word, etc.)
Comprehensive information providing an introduction to GIS technology, data gathering, modeling, information retrieval, and applications with colored maps, graphs, diagrams, and photos.
Chapter on geographic information systems from a Wildlife Society publication with detailed information on geographic information systems, data structure, image processing, data analysis, application to waterfowl management, and data sources.
Overview of the environmental monitoring component of the international program at the EROS Data Center using Geographic Information Systems (GIS) technology, with links to data, partners, publications, and workshops.
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).
The Geospatial Data Clearinghouse is a collection of over 250 spatial data servers, with digital geographic data for use in Geographic Information Systems (GIS), image processing systems, and other modeling software. Searchable by metadata.
This site is a prototype clearinghouse for techniques, procedures, documentation, software and macros that support the creation, use and release of digital geologic map datasets.
Homepage for geospatial technologies activities with links to Biological Resources Division Geospatial Technology programs and GIS laboratories, and support for GPS users.
