WHAT IS GIS?
- A geographic information system (GIS) integrates hardware, software, and data for capturing, managing, analyzing, and displaying all forms of geographically referenced information.
- GIS allows us to view, understand, question, interpret, and visualize data in many ways that reveal relationships, patterns, and trends in the form of maps, globes, reports, and charts.
- A GIS helps you answer questions and solve problems by looking at your data in a way that is quickly understood and easily shared.
- GIS technology can be integrated into any enterprise information system framework.

Note: All data is in ESRI shapefile format.
Various GIS data ZIP files are formatted for shapefile‑compatible software. Because these files require specialized GIS platforms, they cannot be fully converted to an accessible format.
