GIS Data Resources

ArcGIS.com - Online mapping tool that allows you to save and share maps that you are creating.

ArcExplorer -A free, lightweight GIS data viewer with limited functionality to view and query geographic data.

ArcReader - Free, easy-to-use mapping application that allows users to view, explore, and print maps.

CrimeStat - Free software package that complements statistical/centrality metrics from ArcGIS 9.x statistical software package.

Google Earth- Google Earth Software that you can download onto your own compute.

ArcGIS Explorer- Free ArcGIS Explorer. It looks and feels like Google Earth, but you can add own data and do basic analysis.

ESRI Support Page - Answers any question revolving around ERSI software or GIS techniques.

ESRI Developer Network - Extent the capabilities of Desktop ArcGIS with simple tools or make your own using snippets of code.

Note: GIS data come in a variety of formats and projections. While data formats (coverages, shape files, CADD files, interchange, personal geo-databases, DLG) can easily be converted from one format to the next, doing so may compromise its topology, locational or attribute data. In addition, some state agencies publish their data using a statewide projection such as state plane coordinate system. Be sure to consult the metadata or the publisher regarding the projection information and previous processing if it is not declared. Updated as of 10/14/2010.

Nationwide Data Resources

DLG Data - Digital vector data derived from USGS maps and related sources. Based on the line, polygon and point work for 1:24,000 USGS quadrangles. Availability changes from quadrangle to quadrangle. DLG data are stored in SDTS (Spatial Data Transfer System). The goal of SDTS is to serve as a happy medium for storing and expressing data between dissimilar computer systems. Refer to the SDTS Web site for converting between SDTS native format and your specific GIS format.

National Atlas - Interesting geological, climatic, environmental and other data at a relatively low scale.

TIGER 2000 Data - Free GIS data organized by state produced by the U.S. Census Bureau in shape file format. Contains a lot of census data and low scale utility and infrastructure data.
