Regional Open Data

CAPCOG Regional Open Data website is an interactive-map website that increases accessibility to regional information and makes the data easily downloadable. The website enhances the GIS Program’s ability to be a single resource of regional geographic information.

Hosted by ArcGIS Online, the site allows users to visually review numerous datasets before downloading the information for their own use. Currently available datasets include items such as city limits; floodplain boundaries; school district boundaries; the location of airports and parks; and archived street centerlines. Parcel boundaries also are available by county.

CAPCOG has generated a number of datasets located on the website but also has compiled datasets from other entities. Some data placed on the website has more up-to-date counterparts such address points and street centerlines, which are packaged with the purchase of the Capital Area Addressing & Referencing Map dataset.

Go to the CAPCOG Regional Open Data site.


Capital Area Addressing & Referencing Map (CAAR Map) is a commonly requested mapped dataset. It is a robust GIS dataset covering the 10-county region of monthly updated information that includes the following data layers:

  • address points
  • street centerlines
  • city limits
  • zip codes
  • emergency service zones

This dataset will soon be available on the CAPCOG Open Data website.
