Description
A characterization of the data, including its intended use and limitations.
Abstract:
Connecticut Routes is a 1:100,000-scale, feature-based layer that includes Interstate Highway, US Route, State Route, and route connectors for Connecticut. It is derived from the Connecticut Route Segments layer, which is based on spatial information from the U.S. Bureau of Census that was published for Connecticut by the University of Connecticut, Center for Geographic Information and Analysis. The spatial information (line feature geometry) from the U.S. Bueau of Census was compiled for the year 2000 and used to create a continuous line feature for each interstate highway and route shown on the State Tourism Map 2002-2003 published by the Connecticut Department of Transportation. The Connecticut Routes layer does not include local roads, highway entrance and exit ramps, highway rest areas, exit numbers, house address, traffic direction, or traffic volume information. Features are linear and represent divided and undivided route centerlines mapped at 1:100,000 scale (1 inch = 1.578 mile).
Purpose:
Connecticut Routes layer is used to cartographically represent individual routes on a map with line symbology that classifies routes by type and with label symbology that places highway and route number shields along each route. Display the Connecticut Routes layer with the Connecticut Street Network State Plane, TIGER/Line 2000 layer to depict routes (with highway and route number shields) and local roads (with street names) on a map. The Connecticut Street Network State Plane, TIGER/Line 2000 layer was compiled and published by the University of Connecticut, Center for Geographic Information and Analysis and is also based on information from the U.S. Bureau of Census.
Supplemental information:
Each route is a continuous line feature that is the result of merging (appending) line features from the Connecticut Route Segments layer. The ArcView 3.3 Avenue Script that creates the Connecticut Routes shapefile from the Connecticut Route Segments shapefile is named zViewMakeRoutes.txt and is included with the Connecticut Route Segments shapefiile download from the State of Connecticut, Department of Environmental Protection Website. This script merges all linear segments that comprise each route in the Connecticut Route Segments shapefile into a single, continuous linear feature for the Connecticut Routes shapefile.

+ Data Structure and Attribute Information
Overview
Summary of the information content of the data, including other references to complete descriptions of entity types, attributes, and attribute values for the data.
Entity and attribute overview:
Includes linear route features such as highways, routes, and connectors. Information encoded about features includes route class and number. Use the ROUTECLASS attribute to symbolize routes by type. Use the ROUTENO attribute to label routes with interstate highway and route number shields. For labeling Interstate highways, query for ROUTECLASS="Interstate" and label the features with the ROUTENO attribute using an interstate highway shield symbol. For labeling US Routes, query for ROUTECLASS="US Routes" and label the features with the ROUTENO attribute using a US Route shield symbol. For labeling State Routes, query for ROUTECLASS="State Route" and label these features with the ROUTENO attribute using a State Route shield symbol. Also, use the SCALELEVEL attribute to define a layer or theme of routes appropriate for display at different scales. There are 6 scale levels. For example, when displaying routes between 1:1,500,000 and 1:500,001 scale, set the layer definition query to SCALELEVEL = 1; between 1:500,000 and 1:200,001 scale, set the layer definition query to SCALELEVEL <= 2; between 1:200,000 and 1:100,001 scale, set the layer definition query to SCALELEVEL <= 3; between 1:100,000 and 1:50,001 scale, set the layer definition query to SCALELEVEL <= 4; for larger than 1:50,001 scale, set the layer definition query to SCALELEVEL <= 5; and for larger than 24,001 scale, set the layer definition query to SCALELEVEL <= 6.

+ Data Quality and Accuracy Information
General
Information about the fidelity of relationships, data quality and accuracy tests, omissions, selection criteria, generalization, and definitions used to derive the data.
Logical consistency report:
Line features conform to the following topological rules. Lines are multi-part so that sections of divided and undivided highways are represented as a single line part or two parallel line parts of the same line feature, respectively. Lines do not self overlap. Lines overlap other lines where routes merge along the same stretch of roadway so that route number shields can be automatically labeled and placed for all routes that share the same geometry. Lines also overlap other lines where routes cross at road intersections. For cartographic purposes, lines overlap in the following hierarchical order: Interstates overlap U.S. Routes, U.S. Routes overlap State Routes, and State Routes overlap route connectors. Lines do not intersect, and all nodes anchor the ends of lines. Lines do not overshoot or undershoot other lines they are supposed to meet. The tests of logical consistency for the Connecticut Routes layer were performed by the State of Connecticut, Department of Environmental Protection using ArcView 3.3 software and an Avenue Script named zViewMakeRoutes.txt that processes features from the Connecticut Route Segments layer. The tests of logical consistency for the Connecticut Route Segments layer were performed by the State of Connecticut, Department of Environmental Protection using ESRI ArcInfo software to maintain feature topology in ArcInfo coverage format. For additional information, refer to the Logistical Consistency Report for the Connecticut Route Segments layer. Due to the topology verification process, there may be minor differences in feature geometry between certain features in this layer and the original data source from the University of Connecticut, Center for Center for Geographic Information and Analysis.
Completeness report:
The completeness of the data reflects the content of Connecticut State Tourism Map 2002-2003 published by the Connecticut Department of Transportation. This layer includes all highways and routes depicted on the Connecticut State Tourism map, with feature geometry based on information from the U.S Bureau of Census that was published for Connecticut by the University of Connecticut, Center for Geographic Information and Analysis. This data does not include local roads, interstate highway entrance ramps, exit ramps, exit numbers, rest areas. This data is not updated.
Attribute Accuracy
Accuracy of the identification of data entities, features and assignment of attribute values.
Attribute accuracy report:
The Connecticut Routes retains the accuracy of the attribute information from the source layer and is comprised of four basic feature types: Interstate Highways, U.S. Routes, State Routes, and route connectors. Each line feature describes an entire route. Each route includes five attributes: ROUTE, ROUTECLASS, ROUTENO, ROUTENAME, and SCALELEVEL. For example, ROUTE="Interstate 95", ROUTECLASS="Interstate", ROUTENO="95", ROUTENAME="", and SCALELEVEL="1" are attribute values for the Interstate Highway 95 line feature. Values are within defined domains. The accuracy test for ROUTE, ROUTECLASS, ROUTENO, and ROUTENAME attributes was conducted during the creation of the source layer (Connecticut Route Segments) by comparing the routes as they are published on the Connecticut State Tourism Map 2002-2003 with interactive displays of the routes segments on a computer graphic system. Each route was individually tested by visually inspecting and comparing its geometry in relation to road features in the Connecticut Street Network State Plane, TIGER/Line 2000 layer. Each route was highlighted in color and followed from end to end. Several tests were made to compare, edit and verify CLASS and ROUTE attribute values in the Connecticut Route Segments layer. These attributes were programmatically copied and automatically incorporated into the Connecticut Routes layer by the ArcView 3.3 Avenue script that creates the Connecticut Routes layer. Attribute values were not manually entered in the Connecticut Routes layer.
Positional Accuracy
Accuracy of the positional aspects of the data.
Horizontal accuracy report:
The horizonal positional accuracy of this data is no better than United States National Map Accuracy Standards for 1:100,000-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 (167 feet) measured on the publication scale of a USGS 1:100,000-scale topographic map. The following description of horizontal accuracy is taken from the metadata for the original data source for the Connecticut Routes layer, which is the Connecticut Street Network State Plane, TIGER/Line 2000 layer. It cautions against using these data for measurement and detailed, large scale mapping  purposes.The information presented in these files is provided for the purposes of statistical analysis and census operations only.  Coordinates in the TIGER/Line files have six implied decimal places, but the positional accuracy of these coordinates is not as great as the six decimal places suggest.  The positional accuracy varies with the source materials used, but generally the information is no better than the established national map Accuracy standards for 1:100,000-scale maps from the U.S. Geological Survey (USGS); thus it is NOT suitable for high-precision measurement applications such as engineering problems, property transfers, or other uses that might require highly accurate measurements of the earth's surface.  The USGS 1:100,000-scale maps met national map accuracy standards and use coordinates defined by the North American Datum, 1983.  For the contiguous 48 States, the cartographic fidelity of most of the Census 2000 TIGER/Line files, in areas outside the 1980 census Geographic Base File/Dual Independent map Encoding (GBF/DIME) file coverage and selected other large metropolitan areas, compare favorably with the USGS 1:100,000-scale maps.  The Census Bureau cannot specify the accuracy of features inside of what was the 1980 GBF/DIME-File coverage or selected metropolitan areas.  The Census Bureau added updates to the TIGER/Line files that enumerators annotated on maps sheets prepared from the Census TIGER data base as they attempted to traverse every street feature shown on the Census 2000 map sheets; the Census Bureau also made other corrections from updated map sheets supplied by local participants for Census Bureau programs. The locational accuracy of these updates is of unknown quality.  In addition to the Federal, State, and local sources, portions of the files may contain information obtained in part from maps and other materials prepared by private companies.  Despite the fact the TIGER/Line data positional accuracy is not as high as the coordinate values imply, the six-decimal place precision is useful when producing maps.  The precision allows features that are next to each other on the ground to be placed in the correct position, on the map, relative to each other, without overlap.

Process step information
Process Step 1
Process description:
Create Connecticut Routes layer - The automated process for creating (deriving) the Connecticut Routes layer from the Connecticut Route Segments layer is documented in an ArcView 3.3 Avenue script named zViewMakeRoutes.txt, which is included with the Connecticut Route Segments shapefile download at http://www.dep.state.ct.us/gis. This script creates a shapefile named routes.shp based on information from the routesegments.shp shapefile. This script creates a single, continuous linear feature for each route by merging (appending) linear features that define the sections or shorter segments for each route from the Connecticut Route Segments layer. This script assigns route class and route number attribute values based on information from the Route Segments layer. Also, Scale Level values of 1, 2 or 3 are assigned to each route base on information that is hard coded in the zViewMakeRoutes.txt file.

Process Step 2
Process description:
Added 3 more values to the ScaleLevel attribute by expanding the domain range from 1-3 to 1-6 in order to more finely select routes for display at smaller map scales. Routes were reassigned ScaleLevel values and are now organized into more ScaleLevel categories with fewer features in each. Feature geometry was not edited or updated. This process step resulted in creating the 2006 edition of the Routes layer.

Metadata Standards
Description of the metadata standard used to document the data and reference to any additional extended profiles to the standard used by the metadata producer.
Standard name: FGDC Content Standards for Digital Geospatial Metadata
Standard version: FGDC-STD-001-1998
Time convention: local time
Metadata profiles defining additonal information:
Profile: ESRI Metadata Profile
FGDC Plus Metadata Stylesheet
Stylesheet: FGDC Plus Stylesheet
File name: FGDC Plus.xsl
Version: 2.2
Description: This metadata is displayed using the FGDC Plus Stylesheet, which is an XSL template that can be used with ArcGIS software to display metadata. It displays metadata elements defined in the Content Standard for Digital Geospatial Metadata (CSDGM) - aka FGDC Standard, the ESRI Profile of CSDGM, the Biological Data Profile of CSDGM, and the Shoreline Data Profile of CSDGM. CSDGM is the US Federal Metadata standard. The Federal Geographic Data Committee originally adopted the CSDGM in 1994 and revised it in 1998. According to Executive Order 12096 all Federal agencies are ordered to use this standard to document geospatial data created as of January, 1995. The standard is often referred to as the FGDC Metadata Standard and has been implemented beyond the federal level with State and local governments adopting the metadata standard as well. The Biological Data Profile broadens the application of the CSDGM so that it is more easily applied to biological data that are not explicitly geographic (laboratory results, field notes, specimen collections, research reports) but can be associated with a geographic location. Includes taxonomical vocabulary. The Shoreline Data Profile addresses variability in the definition and mapping of shorelines by providing a standardized set of terms and data elements required to support metadata for shoreline and coastal data sets. The FGDC Plus Stylesheet includes the Dublin Core Metadata Element Set. It supports W3C DOM compatible browsers such as IE7, IE6, Netscape 7, and Mozilla Firefox. It is in the public domain and may be freely used, modified, and redistributed. It is provided "AS-IS" without warranty or technical support.
Instructions: On the top of the page, click on the title of the dataset to toggle opening and closing of all metadata content sections or click section links listed horizontally below the title to open individual sections. Click on a section name (e.g. Description) to open and close section content. Within a section, click on a item name (Status, Key Words, etc.) to open and close individual content items. By default, the Citation information within the Description section is always open for display.
Download: FGDC Plus Stylesheet is available from the ArcScripts downloads at www.esri.com.
