Between January of 2011 and June 2013, MassGIS completed standardization of Property tax parcels for all communities across the Commonwealth. Parcels provided an excellent start on mapping address locations; these locations were needed as part of developing the mapping needed to support 9-1-1 call routing in the Next Generation System (launched in December of 2017). At the time Boston parcels were not included because of the cost and because the existing Boston data was suitable for the NG911 project’s needs.
Information for assessors
These pages for municipal assessors and others explain the value of maintaining standardized parcel mapping:

Information for map maintenance service providers
Since MassGIS embarked on the standardized parcel mapping project, the GIS consulting firms working in Massachusetts, regional planning agencies and the principal providers to Massachusetts communities of CAMA software have supported and promoted the project. The guide below explains the processes.
In February of 2018, MassGIS staff performed a series of webinars for municipal GIS staff to gain a better understanding on how to update the parcel data to the standard. A PDF version of the presentation is below.
