What is GIS? GIS is the integration of computer based mapping with database systems that allow for storing, displaying, and analyzing data. Components: Computer System Spatial Data Analytical Framework
Software for Users Landview 6 C3.301:6 Installed on Government Information Workstation EPA, Census Bureau and USGS Data National Atlas www.nationalatlas.gov
Software for Designers Vector Describes data in terms of: Points: fire hydrants, airports, cities Lines: highways, rivers Polygons: districts, counties, or states Standard Software: ArcGIS (www.esri.com)www.esri.com Raster Describes data in terms of pixels Aerial Photography Satellite Imagery Standard Software: ERDAS Imagine®
Federal Data Sources Bureau of Transportation Statistics http://www.bts.gov Cartographic Boundaries of Census, County, State, Metropolitan Areas Vector files for the Federal Highway System and Water Bureau of the Census http://www.census.gov/ Cartographic Boundary Files Population Data USGS Remote Sensing Data Elevation and Hydrology: http://edc.usgs.gov/geodata/http://edc.usgs.gov/geodata/ Geologic Maps: http://ngmdb.usgs.gov/http://ngmdb.usgs.gov/ EPA Landview www.geodata.gov www.geodata.gov NOAA – Climate Data http://www.ncdc.noaa.gov
Transportation National Transportation Atlas Database (NTAD): TD12.17:AT6 http://www.bts.gov/publications/national_tran sportation_atlas_database/2006/ http://www.bts.gov/publications/national_tran sportation_atlas_database/2006/ A set of nationwide geographic databases of transportation facilities, transportation networks, and associated infrastructure. These datasets include spatial information for transportation modal networks and intermodal terminals, as well as the related attribute information for these features.
