The Geographic Names layer, published by the State of Connecticut, Department of Environmental Protection, contains information about the natural, physical and some cultural features in Connecticut and nearby portions of Massachusetts, New York and Rhode Island. This is the Department of Environmental Protection's repository for geographic feature names information and includes bars, bays, beaches, channels, cliffs, falls, flats, gaps, hills, hill ranges, islands, lakes, ledges, points, populated places, reefs, ridges, rivers, rocks, swamps, towns, and valleys. It does not include structures and facilities such as airports, bridges, cemeteries, churches, highways, hospitals, parks, railroads, roads, schools, towers, or universities. This Geographic Names layer is based on some information from the Geographic Names Information System (GNIS), published by the U.S. Geological Survey, and from spatial data and hard copy maps compiled by the State of Connecticut, Department of Environmental Protection. The layer is comprised of point features with information in related data tables that hold the unique identification number, name, short name, alternate name and type of each geographically named feature. This layer describes the location of each geographically named feature by state and by Connecticut town (municipality). Data is compiled at 1:24,000 scale and is periodically updated.
For additional information about the national Geographic Names Information System, contact the U.S. Geological Survey at www.geonames.usgs.gov. Depending on data format, additional related attribute data tables may not included with the distributed data, but are available upon request. Refer to the Entity And Attribute Overview section of this metadata for descriptions of these related data tables.

Scale Level - A numeric code that organizes map labeling features into separate groups used to control the number of features labeled at different map scales. Over six groups (scale levels) of map label point features can be queried and labeled. Scale Level values range from 1 to 7 and closely correspond with the Scale Level ranges established for the related Hydrography, Waterbody, and Named Waterbody layers. More features are included in the higher Scale Levels. For example, Scale Level 1 includes only a few map label points for a few major rivers. This level is intended for a small map of Connecticut. Conversely, Scale Level 6 includes all waterbodies, other non-waterbody geographic features, and is intended for more detailed maps shown at 1:24,000 scale, for example. Use the Scale Level and the associated attribute, Is Map Label, to define a set of map label point layers that are displayed at different map scales. For example, a map label point layer defined by the SQL expression, ISMAPLABEL = "True" and SCALELEVEL <= 1, only labels a small number of large waterbodies, whereas a map label point layer defined by the SQL expression, ISMAPLABEL = "True" and SCALELEVEL <= 6, labels many more features and is intended for larger scale maps. Note, the line and polygon features that make up the Hydrography, Waterbody, Named Waterbody layers are also assigned similar scale level attribute values, which can be used with the Geographic Names layer to control water features both shown and labeled at different map scale ranges. Scale Levels are additive so include all Scale Levels below the desired level in a definition query. For example, use the following SQL expression to query for Scale Level 4 features - ISMAPLABEL = "True" and SCALELEVEL <= 4. Note the use of the <= (less than or equal to) operator in the SQL expression. (Source: State of Connecticut, Department of Environmental Protection)

Information encoded about these point features is used to cartographically label or center small-sized maps on geographically named features. This feature class includes two sets of points. One set is for labeling maps with geographic names and the other set is for navigating (centering) a map on individual geographically named features such as a hill or pond. Some points are only used for map labeling purposes, some points are only used for map navigation purposes, and some points are used for both a map labeling and a map navigation purposes. Two attributes, ISMAPLABEL and ISMAPNAV, define these two sets of points. Map Label Points - ISMAPLABEL = "True" Use the ISMAPLABEL, STATE_COD and SCALELEVEL attributes to define a set of map label points appropriate for display at a particular map scale. For example, use the SQL expression, ISMAPLABEL = "True", to define a layer with all map label points. Use the SQL expression, ISMAPLABEL = "True" and STATE_COD = "CT", to define a layer with map label points for Connecticut. For example, use the SQL expression, ISMAPLABEL = "True" and STATE_COD = "CT" and SCALELEVEL <= 5, to define a layer with map label points appropriate for display in Connecticut between 1:75,000 and 1:100,000 scale. Or use the SQL expression, ISMAPLABEL = "True" and STATE_COD = "CT" and SCALELEVEL <= 6, to define a layer with Connecticut map label points appropriate for display between 1:24,000 and 1:75,000 scale. Typically, map label points are labeled without showing the actual point features on the map. Do not symbolize point features; assign them no color. Just label the points with their geographic name. Create label classes according to geographic name categories and assign different text symbology to each class. For example, geographic names that are hills are typically labeled with black text and water bodies are usually blue. The CATEGORY attribute in (the related GeoName data table) classifies features according to whether each one is a bay, beach, hill, lake, populated place, waterbody, etc. So geographic name labels based on CATEGORY = "Hill" can be shown in black, and geographic name labels with CATEGORY = "Waterbody" can be shown in blue. It is possible to reduce the number of classes and achieve the same labeling results by using the AV_LEGEND or IMS_LEGEND attribute to classify labels into broader categories than those provide by the CATEGORY attribute. AV_LEGND and IMS_LEGEND attributes combine features into a smaller number of categories for the purpose of simplifying the assignment of label text symbology to similar types of geographically named features. Also, position the label text to the upper right of the point location and use the SHORT_NAME attribute as the label field for all map label point features. Map Navigation Points - ISMAPNAV = "True" Use the SQL expression, ISMAPNAV = "True", to define a map navigation layer with center points for navigating maps to all geographically named features. Use the NAVSCALE attribute to obtain an appropriate map scale for centering the map on a particular map navigation point. Map navigation points are not to be visually displayed on a map. Rather, they are intended to be used as a data source for gazetteer and place name-searching applications where a form is used to search for a geographically named place that the map can be panned to. There is one map navigation point for each Connecticut town that a geographically named feature is located in. For example, a hill will have one map navigation point located in the one town that the top of the hill is located in. However, a river will have a map navigation point located on the river in each town that it flows through. Use the NAME attribute when searching and querying for map navigation point features by geographic name. Other Attributes The STATE_COD and TOWN_NO attributes encode which state and Connecticut town each point feature is located in. Use the TOWN_NO attribute as the join key field to the Town data table with the TOWN attribute that holds the town name. Use the GEONAME_NO attribute as the join key field to the GeoName attribute data table with the NAME and SHORT_NAME fields that hold the full and abbreviated name of the feature such as "Connecticut River" and "Connecticut R", respectively. Use the SHORT_NAME attribute as the label field for all map label point features. Use the NAME attribute when searching and querying for map navigation point features by geographic name. Use the DATA_SRC, SRC_KEY, and SRC_KEYVAL attributes to reference (link) the geographic names to features in other source data layers such as Hydrography Master.
This metadata includes a complete description of the entity types, attributes, and attribute values for this data set. No other reference material exists.
Many feature names are derived from the Geographic Names Information System (GNIS), which was developed by the U.S. Geological Survey in cooperation with the U.S. Board of Geographic Names. The names of rivers, streams, brooks, reservoirs, lakes and ponds were originally compiled and mapped from various sources, including GNIS, by James Bogar, a Cartographer with the State of Connecticut, Department of Environmental Protection.

Geographic Names is 1:24,000-scale data used to cartographically label or center small-sized maps on geographically named features. The layer includes two sets of point features. One set of points is for labeling maps with the feature names; the other set of points is for centering (navigating) maps on these features. A geographically named feature such as a river or hill may be represented by one or more map label or map navigation point, depending on the geographic area it encompasses. Typically, long rivers are labeled with more than one map label point and include a map navigation point feature for each town they pass through. Conversely, the same point feature is used to both label and navigate a map to smaller geographically named features such as hills, populated places, and valleys. For best results, map label points are labeled without showing (symbolizing) the point features on the map. Simply assign no color to the point symbol, and position the label text to the upper right of the point location. Note that map label and map navigation points do not represent true locations for these features. Specifically, map label points are cartographically placed near and not directly on the feature they label. Points used for labeling maps are assigned a group or scale level attribute value that can be used to control the number of features labeled at different map scales. Over six groups (scale levels) of map label point features can be queried and labeled. The set of map navigation points includes point features for centering maps on the portion of each Connecticut town each geographically named feature is located in. Use this layer with other 1:24,000-scale map data such as the Hydrography, Waterbody, Named Waterbody, and Town layers also published by the State of Connecticut, Department of Environmental Protection. The line and polygon features that make up the Hydrography, Waterbody, Named Waterbody layers are also assigned similar scale level attribute values, which can be used with the Geographic Names layer to control water features both shown and labeled at different map scale ranges. To access all attribute information, relate these Geographic Name point features to the GeoName data table and Town data table using the GEONAME_NO and TOWN_NO as join key fields, respectively. Not intended for hard copy maps printed at map scales greater or more detailed than 1:24,000 scale (1 inch = 2,000 feet.) For official geographic names, use the GNIS layer published by the USGS.
Includes selected Geographic Name Information System point features for all of the USGS 7.5 minute quadrangle areas that cover the State of Connecticut.
This data source is a set of Mylar overlays delineating all rivers, streams, brooks, reservoirs, lakes, and ponds that appear on the 1:24,000-scale 7.5 minute topographic quadrangle maps published by the USGS for Connecticut. The names of the waterbodies shown on these Mylars are based on either waterbody names that appear on the 1:24,000-scale 7.5 minute topographic quadrangle maps, names that appear on a state map of officially named waterbodies published by the State of Connecticut in the 1930's, or local names brought to the attention of the cartographer responsible for compiling the Named Streams, Lakes and Ponds Mylars. The Named Streams, Lakes and Ponds Mylars were originally compiled and mapped by James Bogar, a Cartographer with the State of Connecticut, Department of Environmental Protection.
Hydrography Master is a 1:24,000-scale, polygon and line feature-based layer that includes all hydrography features depicted on all of the U.S. Geological Survey (USGS) 7.5 minute topographic quadrangle maps that cover the State of Connecticut. Hydrography Master encodes the waterbody name information from the Named Streams, Lakes and Ponds Mylar manuscripts (Source 2) and is in ArcInfo Coverage and Shapefile format.
Named Waterbody Master is a 1:24,000-scale, polygon and line feature-based layer that includes all named waterbodies depicted on all of the U.S. Geological Survey (USGS) 7.5 minute topographic quadrangle maps that cover the State of Connecticut. Named Waterbody features include water, dams, flow connectors, aqueducts, canals, ditches, shorelines, and islands. The layer does not include the marsh areas, tidal flats, rocks, shoals, or channels typically shown on USGS 7.5 minute topographic quadrangle maps. However, the layer includes linear (flow) connector features that fill in gaps between river and stream features where water passes through marshes or underground through pipelines and tunnels. Named Waterbody Master is based on (derived from) the Hydrography Master layer and is in ArcInfo Coverage and Shapefile format.
This data source refers to all features combined in one statewide layer. Since initialy published in 1995, subsequent versions of the layer were generated by the CT DEP in order to change data format, convert from NAD 27 to NAD 83, improve the quality and accuracy of feature geometry and feature attribute information, and include additional geographically named features. Consequently, different copies of this layer have been produced over time, representing various steps in the data layer development and maintenance process. Changes made to the entire layer are reflected in metadata process steps where this particular data source is cited as both the Source Used and the Source Produced
Data creation in ArcInfo Coverage Annotation format - Using ArcInfo 7 software, the original map labeling dataset was made in ArcInfo Coverage format with Annotation features based on selected, non-waterbody data points from GNIS (e.g. hills, populated places, rocks) and manually placed stream, lake and bay names depicted on the Named Streams, Lakes and Ponds Mylar manuscripts and encoded in the Hydrography Master layer. All annotation features were manually placed for best cartographic position for 1:24,000 to 1:50,000-scale maps. Feature location and attribute accuracy was visually checked and inspected by symbolizing features according to annotation subclasses on the computer screen and on hard copy paper maps. Feature names were also compared to the source data and USGS 7.5 minute topographic quadrangle maps. Check plot maps were printed at 1:24,000 and 1:50,000 scale to visually inspect digitizing quality and the assignment of attribute values. This initial ArcInfo Coverage included bay, beach, hill, island, lake, points of land, populated place, river, rock, swamp, town, and valley Annotation features.

Data format conversion to Shapefile and Horizontal Datum change - Using ArcInfo 7.1 and ArcView 3.2 software, the data was converted from ArcInfo Coverage Annotation to Shapefile point feature format and from the Connecticut State Plane Coordinate System of 1927 (NAD27) to the Connecticut State Plane Coordinate System of 1983 (NAD83). The NADCON (North American Datum CONversion) data transformation was used. This initial Shapefile included bay, beach, hill, island, lake, points of land, populated place, river, rock, swamp, town, and valley map label point features.
79 Elm Street
Data format conversion to GeoDatabase with addition of map navigation point features - Using a combination of Workstation ArcInfo 8.3, Desktop ArcInfo 9.1, and ArcView 3.3 software, the following modifications were made to the Geographic Names layer. First, more categories of features were incorporated from the GNIS data source. These new categories included bar, channel, cliff, fall, flat, gap, hill range, ledges, reef, and ridge features for Connecticut and nearby portions of Massachusetts, New York and Rhode Island. Second, the data structure of the Geographic Names layer was normalized by converting it from Shapefile to GeoDatabase format and assigning a unique identifier, GEONAME_NO, to each geographically named feature in a new data table named GeoName. Each GeoName record represented a geographic name and was related to one or more point in the Geographic_Name feature class through the GEONAME_NO identifier. STATE_COD and TOWN_NO attribute values were determined for each point feature by overlaying these features with polygon features in a layer named Town Master from USGS, published by the State of Connecticut, Department of Environmental Protection. A new field, SCALELEVEL, was added for labeling different sets of features at different map scales. Groups of features were assigned numeric SCALELEVEL values according to feature class, feature size, and cartographic preference. Through this process for example, map label points are made active for labeling large rivers and lakes at smaller scales than smaller sized lakes and rivers; and more label point features are made active for labeling large features, such as the Connecticut River, at larger map scales. See description of SCALELEVEL attribute for details. All of these point features used for map labeling purposes were assigned an ISMAPLABEL attribute equal to "True". The ISMAPNAV attribute was added to describe a second type of point feature for centering (navigating) small-sized maps on geographically named features. Since the same point feature can be used to both label and navigate a map to smaller geographically named features such as hills, populated places, and valleys, all features other than rivers, lakes and bays were assigned an ISMAPNAV attribute equal to "True". Map navigation points for all rivers, lakes and bays were generated through a combination of steps. For example, using Workstation ArcInfo 8.3, Named Waterbody Master polygon features were intersected with state and town polygons from the Town Master from USGS layer to create polygon label points representing areas where rivers, lakes and bays exist in every town. These waterbody polygon label points represent polygon centroids and were converted to simple point features. The point features for lakes and bays that represented the largest polygon area of the waterbody in each town the lake or bay was located in were identified and used as the basis for map navigation points and assigned an ISMAPNAV attribute equal to "True". The point features for streams that also represented the largest polygon area of the stream in each town the stream is located was temporarily saved for comparison with midpoints for the longest single line stream feature. For each stream, point features representing stream polygon centroids were compared to point features representing stream line midpoints in the following manner. Using ArcView 3.3 software, Named Waterbody Master line features were intersected with state and town polygons from the Town Master from USGS layer to associate a town with each single line stream. Using ArcView 3.3 software, the midpoint for each of these single line stream features in each town was converted to a point feature. Since a stream is represented as a collection of polygon features along wider portions (double-line sections of streams) and linear features along narrower portions (single-line sections of streams), both a polygon centroid and a line midpoint based stream point feature may exist for any one stream-town combination. Consequently, the two sets of (polygon centroid and line midpoint based) stream point features were compared and, if both types of points existed for the same stream-town combination, the polygon centroid based point was used instead of the line midpoint based point as the means for establishing a map navigation point. Otherwise, either the one polygon centroid or one line midpoint based feature defined the map navigation point. Consistent with all map navigation points, the ISNAVMAP attribute for these features was assigned a value of "True". As a result of this process, thousands of points were added to the Geographic Names layer solely for the purpose of being able to search for and center a map on a geographically named feature in every town that it is located in. For large features such as rivers and lakes located completely or partially out of state, only one map navigation point feature exists for each state outside of Connecticut the waterbody is located. All map navigation point features were assigned a corresponding NAVSCALE attribute value of 24000, with the exception of points used to navigate to towns, which were assigned 50000. A new data table, GeoNameOther was added to include other (alternate) names for geographically named features in the GeoName table. It was initially populated with alternate names for some streams, lakes and bays from the Named Waterbody Master layer. The GeoName feature class included map label and map navigation points for bar, bay, beach, channel, cliff, fall, flat, gap, hill, island, lake, ledge, point, populated place, reef, river, rock, swamp, town, and valley geographic names.

The Geographic Names layer retains the feature types and information identified by the State of Connecticut, Department of Environmental Protection. Initially based on information from the USGS GNIS, feature content and attribute information was modified in order to create a layer with multi-purpose point features that serve both map labeling and map navigation functions. Feature level links back to the original GNIS data are not preserved. Feature level links to named river, lake, and bay (hydrography) features maintained by CT DEP are preserved. All attributes have valid values. Values are within defined domains. The accuracy test for most attributes was conducted though a systematic and iterative process of visually verifying the information against the compilation data source such as 7.5 minute topographic quadrangle maps and spatial data layers of named waterbody features maintained by CT DEP. This data quality review process was conducted over a period of many years as new categories of features were added to the Geographic Names layer and as errors were corrected and improvements were made to other layers upon which this layer is based, such as the Hydrography Master layer published by CT DEP.
Point features are approximate representations for labeling and navigating (panning maps) to large area objects (e.g. populated places, hills, sandy beaches, reefs) or areas having well-defined, visible, recoverable, or permanent boundaries or demarcations (e.g. rivers, streams, brooks, reservoirs, lakes, ponds, municipalities). Point features do not accurately reflect the true locations for these geographically named features, but rather where to either cartographically label or center a map on geographically named features, usually at 1:24,000 scale. Most map label point features were manually positioned to avoid conflicts with the features they label; other nearby map labels; and nearby surface water features, transportation features, and built-up areas depicted on USGS 7.5 minute topographic quadrangle maps. The horizontal positional accuracy of this data is no better the United States National Map Accuracy Standards for 1:24,000 scale maps. According to this standard, not more than 10 percent of the locations 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.
This dataset contains information about natural, physical and some cultural features in Connecticut and nearby portions of Massachusetts, New York and Rhode Island identified by the State of Connecticut, Department of Environmental Protection. Data is periodically updated as additional categories of features are included and as errors are corrected.
Point features conform to the following topological rules. Points are single part. There are no duplicate points. However, point features may exactly overlap in situations where the same coordinate location is the basis for defining map navigation points for centering the map on two or more overlapping features. For example, overlapping map navigation points may exist for a named lake and the named stream it is part of or a named bay and the named stream that flows into it. Overlapping map navigation points are allowed if they represent different geographically named features. Overlapping map label points for the same geographically named feature are infrequent and only allowed if their SCALELEVEL values differ. Note that map navigation points for lakes and bays represent centroids for the largest polygon area in each Connecticut town the lake or bay is located. For rivers, map navigation points are either based on the centroid for the largest polygon area or the mid point for the longest single-line stream feature in each Connecticut town the stream is located. For large features such as rivers and lakes located completely or partially out of state, only one map navigation point feature exists for each state outside of Connecticut the waterbody is located. No tests were performed to guarantee desired topology other than visual inspection following a combined manual and semi-automated process of creating these point features.
