Dukes County Full Town Bounds

This polygon feature class contains the land, pond, and offshore areas within Dukes County MA. These data are intended for cartographic display and not survey-grade, legal definition. This dataset was compiled from several other datasets published by MassGIS. The coastline and inland ponds are believed to be at 1:25,000 scale based on wetlands data from the early 2000. The 3-mile extent is from an offshore 1:80,000 scale feature class. The town boundaries (on land) are from the Community Boundaries dataset of 2002. The town bounds across ponds were created by the MVC based on USGS topo maps. All data processing was done in ArcPro using primarily Identity geoprocessing tool to merge the various datasets together & to distinguish land, ponds, and off-shore. The attribute [type] was added to indicate a polygon as land, pond, or offshore. The two key files used from the MVC's data inventory were [town_detailed_duk_noh2o] and [interior_town_arcs6]. Note: There are many town boundary datasets available and discrepancies in the town bounds among those datasets are numerous. This dataset of extents, does not claim to be the 'official' record of town bounds. If you need 'official', survey-grade data, please look elsewhere.
