(OPTIONAL)
This digital parcel data layer is considered to be in the public domain and will become accessible for download and display from the MassGIS website: http://www.mass.gov/mgis
This data may be appropriate for planning purposes. It should not be utilized where legal and surveyed property boundaries are required.
This parcel data is submitted to MassGIS in a file geodatabase. It will be incorporated into the MassGIS SDE database, and may be converted into other GIS data types for future distribution.

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.
Original 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. Any updates to this data have been compiled on more recent orthophotography, base maps, or digital plans.
(REQUIRED) -- (if known, if not "UNKNOWN") scale of the source materials (for example, on a 1:24,000-scale map, the source scale denominator is 24000).

(REQUIRED) -- specify paper map citations and/or original digital parcel citations
(REQUIRED) -- Discuss the quality/origins of the source materials and how they contributed to the level 3 parcels. Do not discuss the processing methodologies in this section. That will go in the "Process Step" area of the FGDC metadata.
(REQUIRED) -- Summarize the processing methodologies used in the conversion/upgrades of the source materials into this digital level 3 parcel dataset, including parameters and tolerances used, if any.

(REQUIRED -- Please fill in correct town IDs and town names before deleting the text in these parentheses)M###TaxPar represents a version of digital municipal parcels for the community of <muni-name> 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 M###Assess 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 M###OthLeg and M###Misc. 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.
