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.

This data retains the political boundary (linear) feature types identified by the USGS and adds new polygon feature types of importance to the State of Connecticut for the purpose of mapping areas of the State of Connecticut and its counties and towns. All attributes have valid values. Values are within defined domains. The accuracy test for the TBARC_COD and TBPOLY_COD attribute values was conducted by comparing the political boundaries published on the source topographic quadrangle maps with 1:24,000-scale check plots or interactive displays of the data on a computer graphic system. These checkplots and computer displays depicted the features in different colors based on their respective TBARC_COD and TBPOLY_COD values for comparison with the paper quadrangle maps. The TOWN_ARC, TOWN_POLY, AV_LEGEND, and IMS_LEGEND attribute values are based on TBARC_COD and TBPOLY_COD values. TOWN_POLY is the English language equivalent of (decodes) the TBPOLY_COD field for polygon features. TOWN_ARC is the English language equivalent of (decodes) the TBARC_COD field for line features. AV_LEGEND and IMS_LEGEND are broad classifications of TBPOLY_COD and TBARC_COD values for polygon and line features, respectively. Based on the TBPOLY_COD and TBARC_COD attribute values, the TOWN_POLY, TOWN_ARC, AV_LEGEND, and IMS_LEGEND fields were populated through table joins to lookup tables. These decode values were not manually entered. The COASTA_COD line attributes for the shoreline features were transferred with the Coastal Arc (coastline) features copied from the Hydrography Master layer. All other polygon and line features were manually selected and assigned COASTP_COD and COASTA_COD values based on their relative landward and seaward orientation to Coastline Arcs. The COAST_POLY and COAST_ARC attributes decode the COASTP_COD and COASTA_COD attribute values and were populated through table joins to lookup tables. The COAST_POLY field decodes the COASTP_COD field for polygon features. The COAST_ARC field decodes the COASTA_COD field line features. The STATE_COD, FIPS, TOWN_NO, and CNTY_COD polygon attributes were manually entered and visually inspected and compared to information on the USGS 7.5 minute topographic quadrangle maps. The TOWN attribute is the English equivalent of (decodes) the TOWN_NO polygon attribute and was populated though a table join to a town lookup table. The STATE_FLG, FIPS_FLG, CONN_FLG, TOWN_FLG, CNTY_FLG, TNO_LEFT, and TNO_RIGHT line attributes were programmatically attributed, basing line attribute values on polygon and line feature topology relationships. The ACREAGE (area in acres) and AREA_SQMI (area in square miles) fields were automatically calculated for each polygon feature based on computer generated feature area in square feet. The LENGTH_MI (length in miles) field was automatically calculated for each line feature base on computer generated feature length.
Polygon features conform to the following topological rules. Polygons are single part. There are no duplicate polygons. Polygons do not self overlap. Polygons do not overlap other polygons. Polygons are bound by lines. Line features conform to the following topological rules. Lines are single part. There are no duplicate lines. Lines do not self overlap. Lines do not overlap other lines. Lines intersect only at nodes, and nodes anchor the ends of all lines. Lines do not overshoot or undershoot other lines they are supposed to meet and intersect. The tests of logical consistency were performed by the State of Connecticut using ESRI ArcInfo software to maintain feature topology in ArcInfo coverage format. The data is topologically clean. The ArcInfo Clean function was repeatedly used following edits to verify topology and enforce a minimum distance between vertices of 4 feet (fuzzy tolerance) and a minimum allowed overshoot length of 10 feet (dangle length).
The completeness of the data reflects the USGS National Mapping Division standards for feature content of the data sources, which are the Large Scale (7.5 minute) Digital Line Graph (DLG) files available from the USGS. For Connecticut, the Large Scale DLG files used to create this layer are for the 1:24,000-scale topographic quadrangle maps published between 1969 and 1984. The data is complete in the sense that it accurately reflects the contents of the most recently published USGS topographic quadrangle maps available at the time the State of Connecticut, Department of Environmental Protection began creating the layer. More recent quadrangle maps have been published by the USGS since 1984; however, the State of Connecticut did not incorporate this information into the layer. This data is not updated.
This data complies with United States National Map Accuracy Standards for 1:24,000 scale maps. According to this standard, not more than 10 percent of the points tested are to be in error by more than 1/50 inch (40 feet) measured on the publication scale of a USGS 7.5 minute topographic quadrangle map.
Town Master from USGS is a 1:24,000-scale, polygon and line feature-based layer that includes all political boundary features depicted on all of the U.S. Geological Survey (USGS) 7.5 minute topographic quadrangle maps that cover the State of Connecticut. Line features include State, county, town (municipal), and borough boundaries. Polygon features depict the geographic areas for individual towns (municipalities) and cities and boroughs within individual towns. This layer is the primary data source for a set of political boundary layers published by the State of Connecticut, Department of Environmental Protection. The Town Master, Town, Connecticut, and Connecticut Mainland layers are all ultimately derived from the polygon and line features of the Town Master from USGS layer. Note, the town boundary between Middletown and 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. Additionally, coastline and island feature information from the Hydrography Master layer was incorporated into the Town Master from USGS layer in order to enclose the land areas encompassed by towns adjacent to Long Island Sound and to define the islands that are part of these coastal towns. Features derived from the Hydrography Master layer are attributed with specific COASTA_COD and COASTP_COD values. Town Master from USGS is in ArcInfo Coverage format.

Create 2005 Edition of Town - The State of Connecticut, Department of Environmental Protection developed an automated procedure to maintain feature topology and attribute integrity for the Town layer by creating (deriving) the layer from a layer named Town Master from USGS. This procedure is documented in an Arc Macro Language (AML) script named MAKECOVER.AML for the political boundary category of data for the State of Connecticut, Department of Environmental Protection. This procedure combined the geometry of certain features and ensured consistent attribute values by programmatically joining lookup data tables to decode numeric code fields and basing certain line attributes on topological relationships between line and polygon features. Topology-based values were obtained for following line attributes: STATE_FLG, FIPS_FLG, CONN_FLG, TOWN_FLG, CITY_FLG, BORO_FLG, CNTY_FLG, TNO_LEFT, TOWN_LEFT, TNO_RIGHT, TOWN_RIGHT, CITY_LEFT, and CITY_RIGHT. For example, given that each line feature inherently has a (from-to) direction, the value for the TNO_LEFT (Town Number Left) line attribute is based the value of the TOWN_NO (Town Number) attribute for the polygon to the left of the boundary line feature. And the TNO_RIGHT (Town Number Right) line attribute is based the value of the TOWN_NO (Town Number) attribute for the polygon to the right of the boundary line feature. The direction of the line feature is arbitrary and usually reflects the direction with which the feature was digitized. Additionally, the MAKECOVER.AML also encoded Boolean type fields that flag (tag) line features such as state boundaries, county boundaries, town boundaries, etc. For example, the CNTY_FLG (Connecticut County Boundary Flag) field stores either a value of "True" or "False" to distinguish county boundaries from other boundaries and is attributed by comparing the value of the CNTY_COD (Connecticut County Code) attribute of the polygon to the left and right of every line feature. If the two CNTY_COD polygon attribute values differ, then the line feature separates towns in two different counties (making it a county boundary) so the CNTY_FLG line attribute is assigned a value of "True". In 2005, all Boolean fields such as STATE_FLG, FIPS_FLG, CONN_FLG, TOWN_FLG, CITY_FLG, and BORO_FLG were converted from storing previously used 1 an 0 numeric values to represent true and false conditions to storing "True" and "False" text string values, respectively. The MAKECOVER.AML creates the Town layer by extracting and processing features from the Town Master from USGS layer. All polygon and line features from the Town Master from USGS layer that defined boundaries in Connecticut were extracted and output to a separate ArcInfo Coverage named TOWN. Subsequently, the CONN_CITY, CONN_BORO polygon attributes and CITY_FLG, BORO_FLG, CITY_LEFT and CITY_RIGHT line attributes were removed and polygon features were dissolved to eliminate smaller city and borough polygon features that were part of (contained within) larger town area polygon features. The MAKECOVER.AML was executed in 2005 in order to derive the Town layer from the 2005 Edition of the Town Master from USGS layer. The name of the resulting ArcInfo coverage created by this automated process is TOWN. Note, all information is based on boundary lines depicted on USGS topographic quadrangle maps with the exception of most of the state boundary in Long Island Sound. The boundary line between the states of Connecticut and New York is described in Special Laws of Connecticut, Volume 16, pages 1104-1108, Senate Bill #322, An Act Establishing The Boundary Line Between Connecticut and New York. This Special Act documents the latitude and longitude coordinates of the state boundary monuments on the ground and points in the waters of Long Island Sound. These geodetic positions are based on Clark's spheroid of 1866 and are in degrees, minutes and seconds (DMS). The following boundary points enumerated in this act were used to define the state boundary in Long Island Sound. Point No. 170: Latitude 40 57 03.228, Longitude -73 36 46.418 Point No. 171: Latitude 41 15 31.321, Longitude -72 05 24.685 Point No. 172: Latitude 41 17 26.341, Longitude -72 01 10.937 Point No. 173: Latitude 41 18 37.835, Longitude -71 55 47.626 Point No. 174: Latitude 41 18 16.249, Longitude -71 54 28.477

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.
