Eligible enhancements to standardized parcel mapping

Review enhancements and identify ones relevant in your community.

The link to the application form is at the bottom of this page.

Description of possible enhancements

  1. Adding additional map features and text labels from existing printed assessor maps or from GIS or CAD format sources.  Eligible features and labels include:
    • Parcel boundary dimensions
    • Lot numbers
    • Lot size
    • Easements and their labels
    • Historic parcel lines
    • Landmark features (e.g., names of water features)

      Building outlines, wetlands, address numbers, and street name labels are NOT eligible as they are available from existing sources at MassGIS.  Features and label items requested must have been present on the version of the assessor maps that was being maintained at the time the standardized version of the maps was created for MassGIS between 2011 and 2013. The purpose of this project is not to add desired content not previously on your tax maps.
  2. Updating the standardized assessor parcel mapping to include changes since the original standardized mapping was created for MassGIS OR adjusting existing parcel mapping maintained in a GIS format to ensure it meets the standard’s requirements. This includes updates for new or reconfigured parcels, including information requirements for enhancement 7 (below).As part of this enhancements, the mapping vendor selected by MassGIS for work in your community will provide you with a spreadsheet file. You will need to contact your CAMA software vendor’s customer service staff and ask them to use that file to bulk-load the ‘LOC_IDs’ from the standardized mapping into your CAMA database. The LOC_ID is used to link a CAMA record to its corresponding map parcel using mapping software. The CAMA vendors are not charging for this service and they have experience working with dozens of communities across the Commonwealth.
  3. Modify or replace an existing automated capability (in-house or through map maintenance provider) OR create an automated capability for producing printed maps.A set of printed or PDF format maps will be produced for a community using the standardized mapping. As necessary, this work can include creating the map sheet index. If this enhancement requires producing maps based on a new and different sheet index, and if you continue to routinely rely on a printed map in your assessing office, then this enhancement can also include the cost of producing a new set of printed maps.

Enhancements #4-8 are for maps in communities with a GIS staff member OR for communities where the maps are maintained by a consultant using GIS software. If your community has a GIS consultant maintaining your tax maps, you should discuss with them which enhancements are needed for your standardizing mapping.

  1. Shifting existing dimension text labels (“annotation”) so that they align with parcel boundaries in the standardized mapping. Note that if you have text labels in your GIS parcel mapping that currently do not line up with your parcel lines, this enhancement does NOT cover improving alignment of text labels that was already poor.
  2. Shifting “derived’ GIS data layers so that they align with parcel boundaries in the standardized mapping. In a municipal GIS, some map features are derived from parcel boundaries (such as zoning overlay districts, school feeder districts, and water supply protection districts). When parcel boundary locations in assessor mapping were modified as part of the standardized mapping project, boundaries in derived data layers no longer aligned with parcel boundaries. This enhancement includes adjusting boundaries of derived data layers to align with the relevant boundaries from the standardized parcel mapping. Note that if your derived data layers are poorly aligned with your existing parcel mapping, this enhancement does not cover correcting this problem. This enhancement only covers replicating the poor alignments against a backdrop of the standardized parcel mapping.
  3. Creating an ArcGIS line feature class for parcel polygons.This enhancement can be selected provided that a line feature class was present in the community’s existing GIS version of its parcel mapping when the standardized version was created for MassGIS.
  4. Adding back attributes of parcels that were not retained as part of creating the standardized mapping.  Attributes added in this enhancement category must have been present on the version of the assessor maps that was being maintained at the time the standardized version of the assessor maps was created for MassGIS.
  5. Up to eight hours of training in using ArcGIS tools for maintaining assessor maps in compliance with Level 3 of the MassGIS standard. The person being trained must be a municipal employee whose current job responsibilities include using ESRI GIS software to maintaining the existing parcel mapping for that community. In addition, for MassGIS to fund this training, the enhancement request must be followed by an email from the supervisor of the proposed trainee. That email must specify the contact information for the supervisor and must state the following:

    “I supervise <name of person> who maintains the assessor parcel maps. If this training is provided, I commit to: 1) ensuring that, following the training, parcel map maintenance will be conducted in compliance with the mapping portion of Level 3 of the MassGIS standard and, 2) to providing the assessor with an annual list of new or changed parcels and their corresponding LOC_IDs.”
  6. Creating updated file for bulk-loading unique identifiers from standardized mapping (the “LOC_IDs”) to your CAMA database. If you have selected Enhancement #2, you do NOT select this enhancement. Select this enhancement only after consultation with whoever maintains your parcel mapping.
