All six states' data were projected to the Massachusetts State Plane Mainland coordinate system, NAD83 datum, units meters, for use with all other MassGIS data. Please note that the layers vary in quality and are distributed for use only in regional mapping.
Each layer has a polygon attribute table and/or an arc attribute table. The items for each are as follows:
MaintenanceAs stated above, MassGIS distributes these layers for use in regional mapping and does not maintain or update them. For web links to each state's GIS program, please see the Contacts page.
