The USGS is the collector of the data (compiler). The State of Connecticut, Department of Environmental Protection is the creator and maintainer of the data layer (editor) and producer (publisher) of this information for use. The 2005 Edition essentially includes the same set of geographic features published in 1994. However, the 2005 Edition differs from information published in 1994 primarily as a result of minor corrections and improvements to feature geometry and feature attribute information. Some feature attribute information (data fields) have been slightly modified and made easier to use. This layer includes information that is relatively static and does not change over time. Data is not updated. Data compiled at 1:24,000 scale.
Connecticut Town Polygon includes the polygon features of a layer named Town. Town is a 1:24,000-scale, polygon and line feature-based layer that includes state, county and town (municipal) boundary features depicted on the U.S. Geological Survey (USGS) 7.5 minute topographic quadrangle maps for the State of Connecticut. This layer only includes information for Connecticut. Line features include State, county, and town (municipal) boundaries. Polygon features depict the geographic areas for individual towns (municipalities). A town may be represented by more than one polygon feature. For example, in addition to representing the portion of a town on the mainland, a polygon feature may also define an island along the coast of Long Island Sound. The layer is based on information from USGS topographic quadrangle maps published between 1969 and 1984 and latitude and longitude coordinates that define the boundary between the states of Connecticut and New York in Long Island Sound. Attribute information is comprised of codes to classify and cartographically symbolize political boundaries by type and identify the geographic areas encompassed by individual towns. Polygon feature attributes include state, county, and town codes and names. Feature length and geographic area are encoded for linear and polygon features, respectively. This layer was originally published in 1994. With the exception of the Middletown-Portand town boundary, the 2005 edition, includes the same features originally published in 1994. The Middletown-Portand 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. Some attribute information has been slightly modified and made easier to use.
Town is 1:24,000-scale base map data. It depicts the location of all state, county and town (municipal) boundaries published on the U.S. Geological Survey (USGS) 7.5 minute topographic quadrangle maps for the State of Connecticut. For base map purposes, use this layer with other 1:24,000-scale base map data such as Hydrography, Waterbody, Named Waterbody, Roads and Trails, Railroads, and Airports. All of these layers include information for Connecticut. Town may be used as a possible data source for other 1:24,000-scale layers having features that should coincide with the political boundaries on the USGS topographic quadrangle maps. Not intended for maps printed at map scales greater or more detailed than 1:24,000 scale (1 inch = 2,000 feet.)
The Town layer only includes town boundaries. It does not include the boundary lines of individual boroughs such as the Borough of Stonington, for example. The boundaries of individual boroughs are included in the layer named Town Master from USGS, which is also published by the State of Connecticut, Department of Environmental Protection. In 2004, the State of Connecticut, Department of Environmental Protection developed automated procedures to maintaining feature topology and attribute integrity for the Town Master from USGS layer and layers derived from the Town Master from USGS layer such as the Town Master layer. Using ArcInfo Workstation 8.3 software and Arc Macro Language (AML) scripting environment, the automated procedures were recorded in an AML file named MAKECOVER.AML for the political boundary category of data published by the State of Connecticut, Department of Environmental Protection. The MAKECOVER.AML maintains the features and feature attribute data for the Town Master from USGS, Town Master, Town, Connecticut, and Connecticut Mainland layers. Use the Town Master layer when mapping town boundaries in Connecticut and nearby portions of Massachusetts, New York and Rhode Island. For additional information related to the original source of data from the U.S. Geological Survey, refer to the Data User Guides and Standards for 1:24,000-Scale Digital Line Graphs and Quadrangle Maps available from the U.S. Geological Survey, National Mapping Program.

Includes polygonal and linear features for political boundary information published on the U.S. Geological Survey 7.5 minute topographic quadrangle maps. Polygon and line features primarily represent town areas and boundaries, respectively, with attributes that distinguish state, county, and town (municipal) areas and boundaries. Information encoded about features includes Town Boundary polygon and arc (line) type classification, standard symbology classification schemes, state, town, county codes, feature area feature area in acreage and square miles, and feature length in miles. Use the AV_LEGEND attribute to symbolize features by type. Use the IMS_LEGEND attribute to more generally symbolize the features by type. Label polygon feature with the TOWN attribute to display town names on a map.

Polygon features depict the geographic areas for Connecticut towns (municipalities), Connecticut islands in Long Island Sound and the waters of Long Island Sound. A town may be represented by more than one polygon feature. For example, in addition to representing the portion of a town on the mainland, polygons features also define islands along the coast.

Coastal Polygon Code. Identifies polygon features that are landward and seaward of a series of connecting hydrography line features that define a shoreline along the coast. These connecting hydrography line features that define the shoreline along the coast are referred to as Coastline Arcs and have a COASTA_COD value of 2. Coastline Arc features from the Hydrography layer have been incorporated into the Town Master layer to enclose town polygon features along the coast. Coastline Arcs define a cartographic boundary that separates inland (landward) features from coastal (seaward) features. This shoreline boundary does not represent a line of demarcation between tidal and non-tidal waters or between fresh, saline and brackish waters. Rather, these features define a standard shoreline boundary that is often incorporated into other layers compiled at 1:24,000 scale for consistency.
