Geographic Information System (GIS)


The Geographic Information System (GIS) department of the Cape Cod Commission supports the planning and regulatory work of the agency and the towns it serves.  We are a service center for regional GIS data and digital maps with hundreds of theme-based layers that can be used by town GIS departments and their consultants, nonprofit agencies, and businesses.

A major responsibility is to provide technical assistance to Cape Cod towns and to other departments in Barnstable County's regional government. Assistance ranges from providing data, analysis, maps, and applications.

NOTES: Analysts using geographic information system (GIS) software are able to produce maps consisting of thematic layers obtained from sources of different original scales. The original maps, by themselves, can be accurate up to a quantifiable point at their original scale, but this no longer applies when GIS software portrays them at a larger scale than they were intended to be used. This concept must be kept in mind when conducting analysis with, GIS or when viewing maps produced by GIS that are presented here.

The information depicted on these maps is for planning purposes only, It is not adequate for legal boundary definition, regulatory interpretation, or parcel-level analysis. It should not substitute for actual on-site survey, or supersede deed research.
