GIS Sites and Resources
- Geographical Information Systems Basics (USGS). Good introduction to GIS, including: data input and how data layers are shown. This is a good page to show someone who does not understand GIS.
- ESRI (Environmental Systems Research Institute, Inc.). The leading GIS company. Several useful ESRI links:
- GIS Glossaries. Selection of glossaries/dictionaries of GIS and Cartographic terms.
- Bird's Eye View GIS. GIS technology service with emphasis on "solving the world's mounting ecological, economic and social problems." Company's focus is on environment, nature, and human ecology.
- Boston Atlas. (Boston Redevelopment Authority ). Excellent example of GIS. Boston maps and satellite imagery with layers for dates from early Boston to the present.
- Historical County Boundaries of United States. Includes GIS data files.
- Dictionary Of Abbreviations And Acronyms In Geographic Information Systems (UC Berkeley).
- Digital Map of the World (MapInfo format). Vector map of the world, in MapInfo TAB format based upon the 1:1,000,000 Operational Navigation Charts & DCW from the U.S. Department of Defense. DMW is the most detailed 1:1,000,000 world map in MapInfo format.
- Electronic Cultural Atlas Initiative (ECAI). This site features cartographic tools for "visualizing and analyzing historical and cultural phenomena." Users may create "maps based on a theme, era and region." The "Projects" section provides examples, and the "Participating" section provides instructions. Also includes information about the underlying technology. Note: Access to some datasets requires a password. Sponsored by the University of California, Berkeley.
- Geo Directory of Products and Services (GeoPlace). Directory of organizations, agencies, commercial companies, GIS, mapping, and other products and services.
- Geologic map databases for the United States: Delaware, Maryland, New York, Pennsylvania, and Virginia (Open-File Report (2005-1325)). Geological maps, data, and metadata for 5 states. Useful for GIS applications with Arc Export, ArcView shapefiles, and Attribute Tables.
- Geographic Resources Analysis Support System (GRASS). Free Geographic Information System (GIS) software used for geospatial data management and analysis, image processing, graphics/maps production, spatial modeling, and visualization. GRASS GIS is currently used in academic and commercial settings around the world, as well as by many governmental agencies and environmental consulting companies. GRASS GIS is an official project of the Open Source Geospatial Foundation (OSGeo).
- GIS Data Depot. Provides FREE GIS data downloads from over a terabyte of GIS data and creates custom spatial data CD-ROMs as an alternative.
- GIS Gateway (U.S. Bureau of the Census). Offers connections to many Geographic Information Systems (GIS) resources available on the Internet.
- GIS MGRS Grid Data layers and UTM zones in GIS Format (US National Geospatial-Intelligence Agency (NGA)). UTM, MGRS Shape files for World and specific regions.
- Graphical Locater. Primarily for data on hydrologic regions (HUC), but also has data for most features. Using a map, locate geographical features and find coordinates, hydrologic data on the feature (and USGS topo map info).
- Great Lakes Information Network Maps and GIS.
- Great Lakes Bathymetry (NOAA/NGDC). Data sets, shape files for each lake, plus other data.
- National Gap Analysis Program (GAP). A Geographic Approach to Planning for Biological Diversity (USGS program). GIS system providing regional assessments of the conservation status of native vertebrate species and natural land cover types and to facilitate the application of this information to land management activities.
- New York GAP Analysis - Part of the GAP program. Involves mapping the distribution of animals and plants on land and in aquatic ecosystems.
