Between 2011 and 2013, MassGIS, the state’s GIS office, completed statewide standardization of assessor tax mapping (except for Boston). However, communities found maintaining the standardized mapping challenging because it did not support a variety of municipal needs. MassGIS has since addressed those needs by funding enhancements to the standardized mapping in many communities. Over 250 communities have now adopted maintaining the standardized assessor mapping. Subsequently, in 2014, the Massachusetts Association of Assessing Officers (MAAO) endorsed maintaining standardized parcel mapping as a best practice for assessors. Tax map standardization is also supported by DOR’s Bureau of Local Assessment, by all the principal CAMA software providers, and by all providers of GIS-based assessor map maintenance services in Massachusetts
MassGIS is pleased to announce that 22 municipalities will have their enhancement work completed by one of six vendors. We anticipate that funding for an additional 35 municipalities will be available in FY 2017.
At the Executive Board meeting of the MAAO held on September 16, 2014 the Board voted unanimously to issue the attached Statement on Standardized Assessor Tax Mapping.
The MAAO is dedicated to providing assistance and advice, along with strong educational programs, to aid the local assessor in the performance of their professional duties. The Executive Board of the MAAO feels strongly that standardized tax mapping will help to provide the tools necessary to assist local assessing jurisdictions in providing the tax payers of their community the type of service that they expect and deserve.
These web pages provide information for municipal assessors and others explaining the value of maintaining standardized parcel mapping. There is also a short explanation of the importance of adding the unique parcel identifier (the "LOC_ID") to your CAMA database. In addition, information to assist those maintaining standardized mapping is also provided. If after consulting these resources you still have questions on either of these topics, please contact Craig Austin at MassGIS
This standard for spatial accuracy and detail of assessor parcel mapping and related attribute information is for developing digital versions of assessor’s property maps for use in planning, property assessment, and map display. Version 2.1, Released May 2012
Many communities now offer GIS map information on-line, including assessing data and maps. This link takes you to a list of links to city and town web sites that offer on-line map information.
