Description: The layer includes active passenger, freight, and MBTA Commuter Rail and Rapid Transit railways, along with abandoned rail lines. In many instances there is more than one track per rail line, and rail yards and spurs are included. The Central Transportation Planning Staff updated and enhanced railroad linework distributed by the United States Geological Survey (USGS) as 1:100,000 Digital Line Graphs (DLGs). The original 1:100,000 DLG data were conflated to the orthophoto-derived 1:5,000 Centerline linework now used in this layer. CTPS added several attributes pertaining to type of service, MBTA Commuter Rail status, rail line ownership, and freight and passenger operation. Stored in ArcSDE and distributed in shapefile format, the statewide layer is named TRAINS_ARC. Other rail data from CTPS are TRAINS_NODE (named station locations) and TRAINS_RTE_TRAIN (MBTA Commuter Rail Routes). In addition, the MBTA Rapid Transit data are stored in separate layers: MBTA_ARC (subway, trolley, Silver Line vehicles) and MBTA_NODE (T stops).
Description: Surface Waters - Newton, Massachusetts. This data layer contains ponds and the Charles River in and around Newton. Previously in support of regional mapping, Newton maintained two separate surface water layers; one originally from Boston Edison and one from MassGIS. The first layer was clipped to the Newton city boundary while the second showed features in surrounding towns. The two layers did not line up well and created odd looking boundaries in the middle of the Charles River. To fix this problem the MassGIS polygons were adopted and a [DISPLAY] field was added to allow the user to show features only within Newton if desired.

Description: Village centers for the City of Newton, MA. There are no village boundaries in Newton, they do not serve any administrative function. Some villages have mroe clearly defined centers than others. These locations are the best approximations of the centers.
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.
