The 2022 cartographic boundary KMLs are simplified representations of selected geographic areas from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). These boundary files are specifically designed for small-scale thematic mapping. When possible, generalization is performed with the intent to maintain the hierarchical relationships among geographies and to maintain the alignment of geographies within a file set for a given year. Geographic areas may not align with the same areas from another year. Some geographies are available as nation-based files while others are available only as state-based files. The cartographic boundary files include both incorporated places (legal entities) and census designated places or CDPs (statistical entities). An incorporated place is established to provide governmental functions for a concentration of people as opposed to a minor civil division (MCD), which generally is created to provide services or administer an area without regard, necessarily, to population. Places always nest within a state, but may extend across county and county subdivision boundaries. An incorporated place usually is a city, town, village, or borough, but can have other legal descriptions. CDPs are delineated for the decennial census as the statistical counterparts of incorporated places. CDPs are delineated to provide data for settled concentrations of population that are identifiable by name, but are not legally incorporated under the laws of the state in which they are located. The boundaries for CDPs often are defined in partnership with state, local, and/or tribal officials and usually coincide with visible features or the boundary of an adjacent incorporated place or another legal entity. CDP boundaries often change from one decennial census to the next with changes in the settlement pattern and development; a CDP with the same name as in an earlier census does not necessarily have the same boundary. The only population/housing size requirement for CDPs is that they must contain some housing and population. The generalized boundaries of most incorporated places in this file are based on those as of January 1, 2022, as reported through the Census Bureau's Boundary and Annexation Survey (BAS). The generalized boundaries of all CDPs are based on those delineated as part of the Census Bureau's Participant Statistical Areas Program (PSAP) for the 2020 Census.

This collection of geo-referenced photos vary with regards to spatial accuracy and resolution. Use the hotlinks below to learn the details of each collection or review MassGIS's new story map explaining all the vintages of aerial photos. Tip: Reviewing that story map might be an easier way to digest the information rather than reviewing the more formal/standard metadata accessible via the hotlinks below.Within the web map certain layers will only be visible at particular zoom extents. If a layer is unavailable to turn on/off, then zoom in or out as needed until the layer becomes active.All photos, except year 1938, are captured during leaf-off (typically late winter/early spring). With the exception of the 1938 & 1990s collection, all photos are in true color. The 1938 & 1990s are in black and white. With regards to Dukes County (which includes the Islands of Martha's Vineyard and the Elizabeth Islands) these are the applicable years of acquisition for those State-wide collections that span multiple years: "1990s collection" -- Only year 1999 for Dukes County"2001-2003 collection" -- Only year 2003 for Dukes County"2008-2009 collection" - Only year 2009 for Dukes County"2011-2012 collection" - Only year 2011 for Dukes County"2013-2014 collection" - Only year 2014 for Dukes CountyPhoto Details (Metadata)1938 Black & White Aerials (georeferenced & hosted by Harvard Forest)1990s Black & White Aerials2001-2003 Color Aerials2005 Color Aerials2008-2009 Color Aerials2011-2012 Color Aerials2013-2014 Color Aerials2015 Satellite Images - Extra Details2019 Color Aerials2021 Color Aerials2023 Color AerialsParcel Lines -- These data are NOT survey grade and are intended for general reference only. The parcel data comply with the MassGIS Level 3 parcel data standard. Each town in Dukes County hires a GIS Consultant to prepare their digital parcel lines and to link the properties to the respective records from the town's assessing database. The linkage is static and not updated in real-time - it is only 'as current' as the day the data was exported from the assessing database. The Martha's Vineyard Commission does not edit nor maintain any assessing data or parcel lines/property bounds. Each town within Dukes County updates their digital parcel data when they see fit (most, typically, update annually). Click on a specific town in this map to see when their parcel data was updated and by whom. Similarly, clicking on a parcel in this "MA Aerial Photos Since 1990s web map" will show you the applicable Fiscal Year the assessing info was exported.

Town of Hampden, MA GIS Viewer

This feature layer contains a zoning layer for each of the 7 towns within Dukes County MA. Most of the data was compiled by the Martha's Vineyard Commission. Older data was created by MAPC staff during the Community Development Plan project in the early 2000s.See dataset's attribute table for last edit date. The date range for edits is wide: 2003 to 2024. The basemap of reference, in some cases (Tisbury) was the current GIS parcel boundary file at time of editing. The other towns seaward extent of zoning will not match the parcel data bounds since a different basemap was referenced at time of editing. The ZoneCode attribute contains the abbreviated zoning name for each district, preceded by the town's ID number.For Zoning Bylaws, see each Town's bylaws website: Aquinnah Chilmark Edgartown Gosnold Oak Bluffs Tisbury West Tisbury

MassGIS Level 3 Parcel Data: Data Fiscal Year: Aquinnah 2019, Chilmark 2020, Edgartown 2021, Gosnold 2015, Oak Bluffs 2021, Tisbury 2021, West Tisbury 2021.Building Info Table: Acquired by MVC from Town Assessors in FY20.Downloaded from MassGIS,, this polygon file represents the parcel bounds for the 7 towns in Dukes County MA (Aquinnah, Chilmark, Edgartown, Godnold, Oak Bluffs, Tisbury, West Tisbury). Each town has their own parcel data consultant and then the data are forwarded to MassGIS for final processing. All data comply with the MassGIS Level 3 Parcel Data Standard. This file geodatabase only includes the TaxPar feature class and Assess table for each town. All TaxPar feature classes were appended into one feature class (Parcels_duk) by the MVC.Each assess table is utilized in that town's respective relationship join (1 to Many) for linking the parcel polygon to the related record(s) in the Assess table. The Assess Table contains info about ownership and assessed values. This is not a detailed building table. If there are multiple owners associated with a property, then the Assess table will have multiple records for that property/parcel (such as for condo parcels).Each building table is utilized in that town's respective relationship join (1 to Many) for linking the parcel polygon to the related record(s) in the Bldg table. The Bldg (building) table contains info about each building on the parcel (such as number of bedrooms, number of bathrooms, the living area square footage, etc.). NOTES of CAUTION: The Living Area Square Footage may not represent the exact same thing in each town. As a generalization, Living Area is interior space that is heated. Regarding West Tisbury, their building table only contains info for one building on the parcel. It is uncertain at this time if the info is the most recent, most primary, or some kind of summarization where multiple buildings on a parcel exist.The field of [assess_mYB] represents the Minimum/Earliest Year Built for any building on the parcel and is appended to the TaxPar feature class based on an analysis of the info provided in the building table. This field [assess_mYB] is utilized in the Historic Structures App found in ArcGIS OnLine.
