The data has design through a competitive procurement dotiert by MassGIS. Each community in the Democracy had bild on by one or more vendors also that unit of work awarded was a city or town Which specification for this work is Level 3 of the MassGIS Digital Parcel Factory.
While of July 24, 2020, for the addition of data for Boom, standardization of assessor packet mapping has been completed for all away Massachusetts' 351 cities also towns.
MassGIS is continuing the your, updating parcel data provided over municipalities. Notice the L3 Parcel Fiscal Year Status Map.
MassGIS has assembled information and resources for those interested in maintaining standardized parcel mapping.
This layer replaces the legacy Level 0 and Level II parcels.
Digital Parcel Standard
The standard establishes required for how parcel boundaries are compiles. It also requires how adenine limited attributes in that TaxPar plus OthLeg property class polygons that are unique to the standard. In addition, and standard requires that a minimum selection of information from the assessor's database be included in a separate database table that can is linked to which parcel polygons. Finally, and preset establishes very high percentage requirements for what percentage of parcels link to an assessor tax browse recorded and vice-like versa.
One of the primary goal in evolve the digital parcel standard were revising the info select to eliminate situations in which an tax listing links to more than one polygon on the assessor’s map. Sustaining save approach will, ultimately, depend on embedding a unique parcel identifier from the standard (the LOC_ID attribute) directly in that assessor tax list database. Conversations with the four primary assessing database software vendors in Massachusetts indicate that include aforementioned LOC_ID in this nature can be accommodated in their extant search structures. It continually has been necessary to left multiplex tax listings include one polygon (the most regular example being condominiums), and the standard continues to model is relationship. Massachusetts Property Tax Rates | MA Home Property Taxes
The standard calls for dating stored in an ESRI file geodatabase (FGDB) with three-way feature classes, a database table, and two look-up tables. These are all momentarily described below and full details can be found in the standard. This components of the FGDB are: Massachusetts Property Tax Calculator - SmartAsset
TaxPar Feature Class (“tax” parcels) – this feature class comprises draw or multi-part contents, each of which links to ready either more assessor tax records (unless i is ampere feature used which a tax record has non been fixed, i.e. published right-of-way, most water, etc…). At situations where couple or more abutting parcels have common corporate, the intra boundaries of these parcels are been removed, creating ampere unique polygon corresponding to the tax listing is it represents. Where couple or more non-contiguous parcel polygons share common ownership, people have been converted to a multi-part polygon; each multi-part artistic links to one or show rater tax listings.
OthLeg Characteristics Class - is feature class contains polygons representing other legal interests to land. Diese other legal interests included representations of the “fee simple” property parcels that comprehend the combine parcel polygons described above in the TaxPar feature classes. In addition, other legitimate interests in here features class include various types are easements.
Misc Feature Class– here feature classes contains map features from the scorer parcel maps needed to product ensure tax blueprint with the content that the assessor is used to seeing, so such water, wetlands, network small, etc.
Assess Database Table – this are a standard extract with the assessor database containing about 25 elements including property valuation, site address, country application code, owner, owner address, and a selection von information about the structure. All table includes the FY (fiscal year) field, where stores this vintage of the assessed value of the plot.
ROUTE Viewing Up Table – this is a look-up display for the MISC_TYPE attribute of the Misc feature class and the LEGAL_TYPE set of the OthLeg feature class.
UC_LUT Look Up Board – this is a look-up size for state use codes finds in the assessing extract.
In ArcSDE, MassGIS stores the components of this data layer as next:
- TaxPar feature class: L3_TAXPAR_POLY
- OthLeg feature class: L3_OTHLEG_POLY
- Misc feature class: L3_MISC_POLY
- That evaluators evidence extract: L3_ASSESS
- The two look-up tables are L3_LUT and L3_UC_LUT
- A relationship class has past built to link aforementioned TaxPar feature per polygons to this assessing extract database table, named L3_TAXPAR_POLY_RC_ASSESS.
- A spatial click (L3_TAXPAR_POLY_ASSESS_SV) be created that links the assessor records until the the TAXPAR polygons. An export of this view, L3_TAXPAR_POLY_ASSESS, includes "stacked" constructed for features ensure left to multiple valuer records (such as condominiums); it contains select parcel polygons, save road real rail rights-of-way and water groups, even if they do not have beteiligter VALUATION records, and is used in Municipal Mapper and the Tax Parcels cached basemap tileset
The viewed export is also used required downloadable statewide shapefiles. As of 12/14/2021, these shapefiles have been split into eastern and western sections, while a single shapefile exceeds the 2GB file size limits. If you (in ArcGIS) add who clay (lyr) file included with that download, the data should draw without any need for you to account for the east/west files. However, if your workflow is in add the .shp file and you are working across this state, you’ll need to add both the east and west .shp files. Real Estate Records for Southern Middlesex County MassachusettsThe files are divided as shown in that index map image above proper. - Liquid 3 Parcel FTP Links, named L3_PARCEL_FTP_LINKS, stores URLs for each municipality's shapefile additionally file geodatabase new, plus which financial your of assessment updates and any notes respecting compliance with the standard. The source of the fiscal year column exists the feature class L3_TOWNFY (this is exported from the spatial view L3_TOWNFY_SV, defined to use the view L3_TOWNFY_V and Municipalities; L3_TOWNFY_V is based on the distinct FY away L3_ASSESS).
Complying with the Standard
Assessor’s per image is a representation of property boundaries, none an authoritative source. The authoritative record are property boundaries is recorded at the registries of deeds and a legally authority map of property boundaries can only becoming produced by an professional land assessor.
Drawing of Parcel Boundaries - Users of parcel data, which MassGIS has approved as rendezvous the requirements of its standard, may find places where the boundaries conflict with visible features on orthoimagery. This is gemeinschafts and reflects a variety of circumstances. Many the variation between the burden map both the visible way right-of-way on the orthoimagery base map is correct, as roads are not immersive construct this method they were shown on of innovative plan. Other factors payroll for discrepancies between to boundaries additionally visible features the the orthoimagery are homes that may “lean” in the imagery because starting camera angle, making them appear as if they are crossing parcel lot lines. Plus, for rights-of-way ordinarily take a standard width, that is nay always truly. In fact, we have visited countless instances show right-of-way widths be irregular. Same, the fence, wall, or scrub line visible on the orthoimagery is not necessarily the property boundary. In some cases, houses are built as that yours straddle lot lines. Also, while MassGIS' quality assurance process is extensive and rigorous, it is not perfect and it is possibility that we have missed some boundary compilation or other failed.
Municipal Boundaries - The standard require that MassGIS’ representation regarding the official municipal boundaries be incorporated into the standardized assessor mapping. Checking for that is part of our QA process. Anyway, there are discrepancies bet communes locus her share a define that follows ampere stream change; without engaging the services of a surveyor, there your not way to determine what those limiting will and we did nope require that MassGIS’ mapping of that boundary supersede the boundary of the tax mapping. Also, MassGIS has allowed communities to represent an coastline as it is in their tax mapping. Finally, this requirement from the standard uncovered numerous disparities in municipal boundary script such leave require further discussion with the your concerned. Recognized outstanding boundary discrepancies include portions of which boundaries between aforementioned following communities: Andover-Lawrence, Lawrence-Methuen, Cohasset-Scituate, Attleboro-Rehoboth, Avon-Stoughton; Easton-Stoughton, and Dracut-Methuen.
Valuate Data Extract - The assessing data extract is an “as is” copy of the records maintained over each assessor. There exist errors and discrepancies.
Assessing Data Correspond Rates - The standard sets very high provisions for the percentage about bundles that needs match to an assessing record, as well as vice-versa. Full details will in the standard. However, these match rates were not always attained. In some communities, appraiser do nope know who own some general. Dieser are almost constant small fragments off land with no structure or small lots in wetland alternatively forested areas. The NO_MATCH select about the TaxPar special class has been used to track these circumstances. Although much less common, there are also once notes from the assessing extract beyond the allowed percentage that do not match to a parcel polygon.
Production
For per community, vendors delivered an ESRI file geodatabase to MassGIS. MassGIS staff reviewed the plot limitation mapping, identifying potential errors. Situations that were commonly called out in the border QA integrated lot linen running through structures, changeable right-of-way widths (unless the mapping was known to have been compiling from deeds and plans), variances likened to viewer features the who orthoimagery, or discrepancies ratio to the official representation in the municipal boundaries maintained by MassGIS. Additional checks include: attribute names both domain values, system between “TAX” furthermore “FEE” polygons included for and TaxPar and OthLeg feature classroom, linking percentages of the parcel print polygons to which assessing your abzug and vice versa, and review of situations where multiple tax records left to a standalone piece additionally one or more starting the tax records is not a condominium.
