Boundary, Parker Watershed, Groveland, Massachusetts - vector

Abstract: 

The political boundary datalayer is a polygon representation of town boundaries created from arcs developed from survey coordinates extracted from the 68-volume Harbor and Lands Commission Town Boundary Atlas for the 351 communities (cities and towns) in Massachusetts. The Atlas was published in the early 1900's and is maintained by the Survey Section of Massachusetts Highway Department. For communities with a coastal boundary, MassGIS has collaborated with Massachusetts Water Resources Authority and the Department of Environmental Protection to complete a 1:12000 scale coastline. The boundary for the coastline was defined as being the upland side of tidal flats and rocky inter-tidal zones. Note that the 351 communities are the official municipal names, not including "villages" or other sections of towns.

Data set ID: 

460

Keywords: 

Short name: 

Groveland_vector

Purpose: 

This datalayer was created for the purposes of providing an up-to-date polygon version of the town boundaries for the 351 communites of the Commonwealth of Massachusetts.   The legislative intent for some boundaries could not be mapped.  Boundaries where that is true are identified in the attribute information.

Data sources: 

Groveland_vector

Methods: 

Boundaries were modified in November and December, 2007, in five locations in Norfolk County, adjusted to match surveyed right-of-way (ROW) plans provided by the Norfolk County Engineering department. Edits included: - Bay Road (Sharon-Stoughton); - Clapboardtree Street (Norwood-Westwood); - Old Post Road (Walpole-Sharon); - Canton Street (Norwood-Westwood and Canton-N-W); - County Street (Dover-Walpole between Medfield and Westwood
