Connecticut Towns for Identify is a 1:24,000-scale polygon feature-based layer with a single polygon feature for each Connecticut town. Polygon features depict the geographic areas for individual towns (municipalities). The layer is based in part on information from USGS topographic quadrangle maps published between 1969 and 1984 and does not reflect official town boundary information. In this layer, a town area is represented as a single polygon feature and includes all of the land and water area encompassed by the town, as generally depicted on a USGS 7.5 minute topographic quadrangle map. Note, polygon features for towns along the coast artificially extend to the CT-NY state boundary in Long Island Sound. Feature attribute information denotes the town and county number and name for each feature. This layer was originally published in 1994. With the exception of the Middletown-Portand town boundary, the 2008 edition includes the same features originally published in 1994. The Middletown-Portand town boundary was corrected and changed from its location, as depicted on the USGS topographic quadrangle maps, from along the banks of the Connecticut River in Portand to the middle of the Connecticut River south of Wilcox Island to the Pecausett Meadows area in Portland.

Connecticut Towns for Identify only should be used to determine (identify) the Connecticut town that a point feature or XY coordinate is located in. It should not be displayed on a map or used for cartographic purposes due to the unusual nature of town boundaries in Long Island Sound. Use these town polygon features to identify the town a point on the land is located in. Also use this layer to identify the town a point located in the waters of Long Island Sound should be associated with (and presumed to be located in), based on proximity to the nearest coastal town. Note that town polygon features of this layer are based on a combination of political boundary information depicted on the U.S. Geological Survey 7.5 minute topographic quadrangle maps and interpolated information. For inland towns, town polygon features are entirely based on political boundary information published on the U.S. Geological Survey 7.5 minute topographic quadrangle maps. For towns along the Connecticut coastline, town polygon features also encompass the waters of Long Island Sound and are based on political boundary information published on the U.S. Geological Survey 7.5 minute topographic quadrangle maps that has been extended and enterpolated by CT DEP to the CT-NY state boundary in Long Island Sound. Label polygon feature with the TOWN attribute to display town names.

Includes one polygon feature for each Connecticut town (municipality). For inland towns, town polygon features are based on political boundary information published on the U.S. Geological Survey 7.5 minute topographic quadrangle maps. For towns along the Connecticut coastline, town polygon features also encompass the waters of Long Island Sound and are based on the political boundary information published on the U.S. Geological Survey 7.5 minute topographic quadrangle maps that has been extended (by CT DEP) to the CT-NY state boundary in Long Island Sound. Note, the USGS 7.5 minute topographic quadrangle maps do not include complete and consistent political boundary information in Long Island Sound between towns along the coast. On these maps, town boundaries do not extend or only partially extend into Long Island Sound. Consequently, to enclose all town polygons in Long Island Sound, the land and near-shore boundaries in Long Island Sound for the following shoreline towns were artificially extended in a southerly direction from their end point shown on the USGS topographic quadrangle map to the CT-NY boundary in the middle of Long Island Sound - Greenwich, Stamford, Darien, Norwalk, Westport, Fairfield, Bridgeport, Stratford, Milford, West Haven, New Haven, East Haven, Branford, Guilford, Madison, Clinton, Westbrook, Old Saybrook, Old Lyme, East Lyme, and Waterford. Areas in Long Island Sound for these towns are not based on official town boundaries. Use these town polygon features to identify the town a point on the land is located in. Also use this layer to identify the town a point located in the waters of Long Island Sound should be associated with (and presumed to be located in), based on proximity to the nearest coastal town. Label polygon feature with the TOWN attribute to display town names.

Polygon features depict the geographic areas for individual towns (municipalities). A town is represented by one polygon feature that includes all of the land and water area encompassed by the town. Polygon features for towns along the coast artificially extend to the CT-NY state boundary in Long Island Sound.
