Conducting GIS analysis using publicly-available data There are many GIS data sources easily accessible from the worldwide web. This topic demonstrates the kind of analysis that can be conducted from two such sources. The first is an income analysis where tabular income data from the U.S. Census Bureau (http://factfinder.census.gov) was combined with U.S. Census TIGER shapefiles and county GIS data to determine income levels in Wake County, NC. The second analysis was conducted using data from the North Carolina Economic Development Intelligence System (EDIS) website (https://edis.commerce.state.nc.us/EDIS/page1.html) EDIS queries can provide quick access to community demographics and business data. It will also generate maps of certain queries.

Applications The U.S. Census Bureau maintains significant quantities of information that can be analyzed with GIS for more comprehensive understanding. Tabular data does not always stand out, but analyzing the spatial aspects can often bring to light facts that were not otherwise apparent. The EDIS website is a useful planning tool for employers and prospective employees looking for jobs in NC.
