Tisbury Roofprints (Source Year 2016)

As of June 2019, these are the most current building roofprints for structures in Dukes County, MA. These roofprints were delineated from aerial photos by MassGIS and their subcontractor. The roofprints are not equivalent to footprints. See MassGIS for full methodolgy details. Roofprints can represent any structure (i.e. house, guest house, business, barn, shed, garage, etc). The MVC has also provided building centriods (produced from the roofprint polygon). All centroids were forced to be located within the roofprint polygon. The MVC also appended some assessor's data (or deduced some info from the assessor's data) for each roofprint centroid. The field of [Status] indicates if a parcel is owned by a Year-round ("YR") or Seasonal ("S") person. This deduction was made based on the owner's mailing address zip code. Off-island zip codes were assigned "S" seasonal and on-Island zip codes were assigned "YR" year-round. The field of [UseType] was deduced from the assessor's use code. "NR" - non residential; "R" - residential
