In MACRIS the points are symbolized to indicate the most common historic designation types: 1) National Register of Historic Places, 2) local historic district, 3) both National Register and local historic district, 4) Preservation Restriction, and 5) inventoried but not designated with one of the previous designations. Less common designations are not symbolized in MACRIS, but are included in the Designations attribute field. MassGIS stores a copy of the point feature class as MHCINV_PT. MassGIS projected the data to the NAD1983 Mass. State Plane Meters Mainland coordinate system.<\/SPAN><\/P>
