A Geographic Information System (GIS) is an integrated system of computer hardware, software, and trained personnel linking topographic, demographic, utility, facility, image and other resource data that is geographically referenced.
The GIS/Mapping division is responsible for functions and applications relating to mapping and the use of property information.
Mapping Layers & Data
Use our GIS Portal to explore and download GIS and mapping data, discover and build apps and engage with others to solve important issues. Analyze and combine datasets using maps or develop new web and mobile applications.
Mapping layers can be downloaded from our GIS Portal for free in ESRI Shapefile format. The files have been compressed (.zip) for faster download. A link has been provided if the data is from an external resource. Data is updated nightly. Metadata is available in the GIS Metadata (PDF).
