Maintaining standardized assessor parcel mapping

MassGIS promotes standardized parcel mapping across the commonwealth

Between January of 2011 and June 2013, MassGIS completed standardization of "Level 3" assessor parcels for all communities across the Commonwealth (except Boston because, especially when balanced versus the cost and the advanced level of Boston’s GIS environment, the quality of the existing mapping was sufficient). This achievement was only possible due to support from municipal staff, particularly assessing staff, and with assistance from mapping consultants, regional planning agencies, and the principal providers of computer assisted mass appraisal (CAMA) software.

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.
