Description: Road segments representing centerlines of all roadways or carriageways in a local government. Typically, this information is compiled from orthoimagery or other aerial photography sources. This representation of the road centerlines support address geocoding and mapping. It also serves as a source for public works and other agencies that are responsible for the active management of the road network.
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.

Description: MxxxOthLeg contains polygons representing other “invisible” legal boundaries such as easements or private rights-of-way that overlap tax parcels.There may be few or even no features in this layer and it is required only if such boundaries are shown on the original assessors map. Only Entity Attributes are listed in this metadata. Please see the TaxPar feature class (or MxxxTaxPar.shp) for all other information.

Description: This datalayer contains points for all vernal pools that have been certified by the Natural Heritage and Endangered Species Program (NHESP) according to the Guidelines for Certification of Vernal Pool Habitat (MA Division of Fisheries and Wildlife, 2000). Vernal pools are small, shallow ponds characterized by lack of fish and by periods of dryness. Vernal pool habitat is extremely important to a variety of wildlife species including some amphibians that breed exclusively in vernal pools, and other organisms such as fairy shrimp, which spend their entire life cycles confined to vernal pool habitat. Many additional wildlife species utilize vernal pools for breeding, feeding and other important functions. Certified vernal pools are protected if they fall under the jurisdiction of the Massachusetts Wetlands Protection Act Regulations (310 CMR 10.00). However, the certification of a pool only establishes that it functions biologically as a vernal pool. Certification does not determine that the pool is within a resource area protected by the Wetlands Protection Act. Certified vernal pools are also afforded protection under the state Water Quality Certification regulations (401 Program), the state Title 5 regulations, and the Forest Cutting Practices Act regulations. The Certified Vernal Pools layer is stored in ArcSDE as CVP_PT. Occurrence records of Certified Vernal Pools from the NHESP database are continuously being added and modified. Those changes will be incorporated into the Certified Vernal Pools datalayer twice annually, in the months of January and July. Questions about the creation of this datalayer should be directed to NHESP at 508-389-6375. For questions relating to the certification of Vernal Pools, please call 508-389-6365.
