M191TaxPar represents a version of digital municipal parcels for the community of Monson that is considered ‘level 3’ compliant per the specifications outlined in the MassGIS Standard for Digital Parcel Files. Its features can be linked in a GIS or database environment to a set of standardized assessing attributes in the table M191Assess by using the unique identifying values in the LOC_ID field. This data is also intended to be used in conjunction with associated (and optional) features in the ancillary data layers M191OthLeg and M191Misc. As one of the data sets identified by Massachusetts’ Strategic Plan for Spatial Data Infrastructure (http://www.mass.gov/anf/research-and-tech/it-serv-and-support/application-serv/office-of-geographic-information-massgis/about-massgis/massgis-strategic-plan.htmll), this data enters the public domain as a valuable resource for mapping, planning, and analysis at all levels of government as well as the private sector.

This parcel layer contains discrete, non-overlapping polygons for each property. Adjacent polygons with common ownership and a single tax record have been retained in the "OthLeg" layer that accompanies this TaxPar layer, and dissolved into single parcels in this TaxPar layer. Some non-adjacent parcels may be represented by multi-part polygons where they share common ownership and a single tax record. Public rights-of-way (ROWs) exist as polygons, not null space. Linework associated with private ROWs are retained in the "OthLeg" layer. Water polygons also representing parcel boundaries have been retained in this TaxPar layer. Additional water features that are not considered parcel boundaries may have been placed in the "Misc" layer that accompanies this TaxPar layer. Easements and other similar non-fee taxable boundaries exist in the 'OthLeg" layer, not the TaxPar layer.

Data compiled or reviewed for horizontal accuracy over the MassGIS color orthos from 2008/2009; these orthos are known to be +/- 10' horizontal; however, this data set cannot be used to reach authoritative conclusions about the horizontal accuracy of the boundaries depicted. That work requires a licensed land surveyor.
Original paper tax maps were digitized in 2008 and have been updated annually by Tighe & Bond using surveys, deeds and other source materials.Some spatial alignment was necessary to meet Level 3 standards in areas not updated since 2008. No additional processing was necessary to meet Level 3 requirements. Data was updated in May 2020 to reflect new parcel splits and owner info.
