Description: 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.
This
datalayer was created for the purposes of providing an up-to-date
polygon version of the town boundaries for the 351 cities and towns 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. This layer contains multi-part
polygons, one for each municipality. The coastline on this layer has
been generalized for small-scale cartography and faster display in web
map services.
