A web map used to visualize available digital parcel data for Organized Towns and Unorganized Territories throughout the state of Maine. Individual towns submit parcel data on a voluntary basis; the data are compiled by the Maine Office of GIS for dissemination by the Maine GeoLibrary, and where available, the web map also includes assessor data contained in the Parcels_ADB related table.This web map is intended for use within the Maine Geoparcel Viewer Application; it is not intended for use as a standalone web map.Within Maine, real property data is maintained by the government organization responsible for assessing and collecting property tax for a given location. Organized towns and townships maintain authoritative data for their communities and may voluntarily submit these data to the Maine GeoLibrary Parcel Project. Maine Parcels Organized Towns and Maine Parcels Organized Towns ADB are the product of these voluntary submissions. Communities provide updates to the Maine GeoLibrary on a non-regular basis, sometimes many years apart, which affects the currency of Maine GeoLibrary parcels data. Another resource for real property transaction data is the County Registry of Deeds, although organized town data should very closely match registry information, except in the case of in-process property conveyance transactions.

Major watershed boundaries as adopted by the Martha's Vineyard Commission in 2015. These boundaries were developed through a collaborative effort between the Martha's Vineyard Commission and SMAST during the MEP process.All parcel data is compiled by CAI Technologies per the MassGIS Level 3 parcel data standard. Most towns have their parcel data updated annually. However, all 6 Vineyard towns are updated at the same time. If you click on a parcel on the map, the pop-up info will indicate the Fiscal Year FY of the data.The assessor's info (i.e. owner, assessed value, etc.) associated with a parcel is a static export from the assessor's database at the time the parcel lines are updated annually. For the most current assessor's info, visit the respective town's AxisGIS website.
