Polygon feature class representing building footprints in Worcester, MA. Original features digitized from 1998 orthoimagery project and updated from 2003 imagery. Further updates from City of Worcester information.Informing Worcester is the City of Worcester's open data portal where interested parties can obtain public information at no cost.

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

This dataset consists of 2-dimensional outlines of all buildings and structures within the Town of Dedham, Massachusetts. This information was originally compiled from 1998 and 2004 orthoimagery sources. Updated features have been derived from roof outlines collected by MassGIS using 2011 orthoimagery and LiDAR and updated with 2013 aerial imagery, scanned plans from the Town of Dedham Building Department, and a planimetric collection from the City of Boston.

As of June 2021, 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. To filter these data by Town_ID: 62 = Chilmark, 89 = Edgartown, 104 = Aquinnah, 109 = Gosnold, 221 = Oak Bluffs, 296 = Tisbury, 327 = West Tisbury.See the full metadata for the roofprint points to learn which year of Assessing data was used for the appended attribute generalizations.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 respective parcel's LOC_ID, Map_Par_ID, and Poly_Type, was appended to the attribute table based on the parcel that the centroid intersected.The other appended attributes were based on the info in the Assess Table (present within the town's parcel file geodatabase). The assess tables were summarized based on Loc_ID (a unique value for each parcel). If multiple Assess records have the same Loc_ID, the MinYrBlt & MaxYrBlt (Minimum Year Built and Maximum Year Built) across all the assess records for that parcel were appended to all structure points on that parcel. While these data may represent a range of construction dates, it may not encapsulate the full range.Why? ...here we go --> The Assess Table is a record for each owner on a parcel. Hence, a parcel with a condo will have multiple records (having the same LOC_ID) within the Assess Table. However, a parcel with multiple buildings but only one owner, will only have one record in the Assess Table. So, in the latter scenario, which Year Built date goes to which building? - the answer is 'I don't know'. That answer requires more in-depth research with the town Assessor &/or building inspector &/or Registry of Deeds.The following info is based on the 'first' record within the assess table for the respective Loc_ID/parcel.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.
