The April 2014 update was accomplished by viewing CCRTA on-line schedules and maps. http://www.capecodtransit.org/ These routes may not show all the possible routes that a bus may take, especially in the case of emergency traffic detours, but represents the general destinations served by the named bus line.These points were digitized by Cape Cod Commission GIS staff based upon observation of on-line maps from the transit agencies.

The Cape Cod Commission and Cape Cod Municipalities may coordinate their efforts to identify and designate Growth Incentive Zones (GIZs), areas particularly desirable and appropriate for concentrated growth and development, and establish corresponding Development of Regional Impact review thresholds unique to and in support of such designated areas. Such a designation furthers values and interests set out in Section 1 of the Act: to maintain and enhance sustainable and balanced year-round economies; to provide opportunities for economic development and growth; to maintain and enhance a variety of housing types and opportunities; to maintain and enhance the availability of desired goods, services and amenities; and to direct and incentivize development to locate into areas with a system of existing or planned synergistic uses, capital facilities, amenities, infrastructure and compact development and away from areas less appropriate or undesirable for this type of development.

The Cape Cod Commission is designing a regional growth policy for the Cape with the goals of creating compact, vibrant, walkable centers in which Cape residents and visitors can live, work, and play. The Geodesign process has been used to identify existing centers of activity across the region that will be the major focus of future growth or redevelopment. GIS analysis was used on parcel data to identify clusters of ideal community characteristics, including civic activity, business activity, and physical form, resulting in a map which identifies both regional and local centers of activity.

This polygon layer was created from the water table contours of the individual water lenses to create a polygon coverage by the Cape Cod Commission.

In 2018, the Cape Cod Commission received a $100,000 Planning Assistance Grant from the Massachusetts Executive Office of Energy and Environmental Affairs to develop a series of context-appropriate housing development prototypes that could deliver needed housing options at densities somewhere between the typical single-family, detached house and the large format multi-family, corridor building that are the dominant forms of residential development today. This effort, Community Resiliency by Design, carried out by the Cape Cod Commission and Union Studio, included various community engagement opportunities to garner feedback on the desired types of housing and strategies proposed while also helping demystify and alleviate concerns around the notion of increased density in appropriate locations. In many cases the prototypes were based on existing building typologies that could be found on the Cape, albeit in very limited numbers.

The Barnstable County locations within the MassGIS "Public Water Supplies" datalayer. This datalayer contains the locations of public community surface and groundwater supply sources and public non-community supply sources as defined in 310 CMR 22.00. Nitrate concentration data has been compiled and added by the Cape Cod Commission. Addtional information is available at http://www.mass.gov/anf/research-and-tech/it-serv-and-support/application-serv/office-of-geographic-information-massgis/datalayers/pws.html.

Initially this data set was generated from a spreadsheet provided by the Cape Cod Chamber of Commerce for an Arts Trail Guide. It was further modified for an economic development project for the Cape Cod Commission titled "Leveraging Cultural Assets for Economic Development: A Practical Guide for Municipal Investment in Arts & Culture on Cape Cod".

Ponds studied as part of the Cape Cod Pond and Lake Stewardship Project (PALS) were classified by the Cape Cod Groundwater Guardian Team led by the Cape Cod Commission and included other organizations. The data was compiled in the early 2000s.

This layer was created by the Cape Cod Commission GIS team to depict depth from erosion and accretion over 40 years. The layer was built from the Mean High Water shoreline that the CCC built for the Cape Cod Coastal Planner (www.capecodcoast.org). This layer displays long-term shoreline accretion and erosion rates based on a forty-year estimate of sediment transport, generated from the Long-Term Rate of erosion from the MA Shoreline Change Project. More information is available here: https://www.mass.gov/service-details/massachusetts-shoreline-change-project. Each individual erosion transect was intersected with the shoreline layer and its long term rate was applied to the shoreline. Segments without a transect were extrapolated based on the closest sediment transport trend. Each shoreline segment was then buffered to the length coded on the line. Accretion rates were buffered seaward and Erosion rates were buffered landward.

The nominated DCPC includes all the ocean waters and land below and air above within Barnstable County, starting from a line drawn 0.3 nautical miles seaward from Mean High Water (MHW) around Barnstable County and extending to 3 nautical miles from MHW, or the state jurisdictional boundary, whichever is farther. This area (521,552 acres total) is coincident with the planning area as defined in the Massachusetts Draft Ocean Management Plan and excludes the Cape Cod Canal and several bays, harbors and embayments as shown on the attached map. Where the bounds of the municipal corporations intersect with a neighboring town, the district boundary ends with the municipal corporation boundary. On January 21, 2010, the Cape Cod Commission will vote whether to accept the DCPC nomination for consideration.

Ocean Management Planning DCPC. The Barnstable County Commissioners nominated the Ocean Management Planning District of Critical Planning Concern (DCPC) on December 16, 2009. The Commissioners made the nomination in anticipation of the final Massachusetts Ocean Management Plan on December 31, 2009. The state created the Ocean Management Plan to coordinate and promote certain types of development within Massachusetts ocean waters
