Other citation details: 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 corrections and improvements to feature geometry and feature attribute information. Previously undetected errors have been corrected. Also, some feature attribute information (data fields) have been slightly modified and made easier to use. Except for periodic corrections, this layer includes information that is relatively static and does not change over time. Data compiled at 1:24,000 scale.

Description

A characterization of the data, including its intended use and limitations.

Abstract: Connecticut Buffered Roads Master is a 1:24,000-scale, feature-based layer of for all of the paved and unpaved roads depicted on all of the U.S. Geological Survey (USGS) 7.5 minute topographic quadrangle maps that cover the State of Connecticut. This layer is cartographic in nature. It is designed to be used with maps printed at 1:24,000-scale that require road symbology similar to the standard established by the USGS for 1:24,000-scale, 7.5 minute topographic quadrangle maps. Two layers, the Buffered Roads Master layer and the Roads and Trails Master layer, are used together for this purpose. Buffered Roads features are linear and run parallel to the road (centerline) features of the Roads and Trails layer. Buffered Roads is a set of parallel lines 50 feet apart that result from a buffer on each side of the Road and Trail (centerline) features by a distance of 25 feet. A width of 50 feet is applied to all roads, regardless of road class, and does not reflect actual pavement width. The Buffered Roads Master layer does not include features on the topographic quadrangle maps that appear as single lines such as hiking trails, small private roads, and old railroad grades. These features are found in the more complete Roads and Trails Master layer. The Buffered Roads Master layer is derived from information from USGS topographic quadrangle maps published between 1969 and 1984 and does not represent the road network in Connecticut at any one particular point in time. The layer does not depict current conditions and excludes many roads that have been built, modified, or removed since the time these topographic quadrangle maps were published. The layer includes buffered centerlines for Interstate highways, US routes, state routes, local roads, unpaved roads, traffic circles, bridges, cul-de-sacs, etc. Trails are not included. Features are linear and approximate road curb lines at 1:24,000 scale. Attribute information is comprised of codes to cartographically represent (symbolize) paved and unpaved roads on a map. This layer was originally published in 1994. The 2005 edition includes the same road features published in 1994, but the attribute information has been slightly modified and made easier to use.

Purpose: Connecticut Buffered Roads Master is 1:24,000-scale base map data. This layer is intended to be used with the Roads and Trails Master layer to reproduce the cartographic symbology established by the USGS for printing roads and trails on the 1:24,000-scale, 7.5-minute topographic quadrangle maps. Cartographically, the Buffered Roads Master layer is used to assign thin, black line symbology to the edges or curb lines of paved and unpaved roads on the quadrangle maps. Paved roads are symbolized with a narrow solid black line. Unpaved roads are symbolized with a narrow dashed black line. Complementing this symbology, the Roads and Trails Master layer is used to assign line symbology that fills in the corresponding buffered road area with solid red or dashed red line work, depending on road class. Line symbology should be assigned to Roads and Trails features Master with AV_LEGEND attribute values equal to Primary Route (wide solid red), Secondary Route (wide dashed red), and Trail (narrow dashed black). Used in combination, Buffered Roads Master symbology outlines the centerline-based symbology applied to the Roads and Trails Master layer. For base map purposes, use this layer with other 1:24,000-scale base map data such as Hydrography Master, Railroads Master, Airports Master, and Towns Master. This layer is a cartographic product and should only be printed on maps at 1:24,000 scale (1 inch = 2,000 feet.).

Supplemental information: In 2004, the State of Connecticut Department of Environmental Protection developed automated procedures to systematically maintain feature topology and attribute integrity for a set of related transportation data produced by the agency during the 1980's and 1980's from the 1:24,000-scale USGS DLGs. These layers include Roads and Trails Master, Roads and Trails, Railroads Master, Railroads, Buffered Roads Master, Buffered Roads, Airports Master, and Airports. Automated procedures were developed using ArcInfo Workstation 8.3 software and the Arc Macro Language (AML) as a scripting environment and recorded in an AML file named MAKECOVER.AML for the transportation category of data for the State of Connecticut, Department of Environmental Protection. 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.

+ 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 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. All lines are software generated using ESR ArcInfo software to buffer selected road features from the Roads and Trails Master layer by 25 feet. 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 verified line feature topology and enforced a minimum distance between vertices of 4 feet (fuzzy tolerance) and no minimum allowed overshoot length (dangle length = 0).

Completeness report: The completeness of the data reflects the feature content of the Roads and Trails Master layer, which is the basis for the Buffered Roads Master layer. The Roads and Trails Master layer is based on information available from the USGS for the 1:24,000-scale topographic quadrangle maps published between 1969 and 1984. For details refer to the Roads and Trails Master layer metadata. The Buffered Roads Master layer 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 Roads and Trails Master layer. Some newer quadrangle maps have been published by the USGS since 1984, however, the State of Connecticut did not incorporate this information into the layer. So compared to the most recent set of topographic quadrangle maps available today, the layer is incomplete, and substantially incomplete when compared to the network of highways and streets in existence today. This data is not updated.

Attribute Accuracy

Accuracy of the identification of data entities, features and assignment of attribute values.

Attribute accuracy report: All attributes have valid values. Values are within defined domains. The accuracy of the ROBUFF_COD attribute values was spot checked by comparing 1:24,000-scale checkplots with the actual quadrangle maps, and using interactive computer graphic displays to compare Buffered Roads features with Roads and Trails features. These checkplots and computer displays depicted the paved and unpaved buffered roads edge lines in different colors based on their respective ROBUFF_COD values. These tests were visual. No manual edit corrections were necessary. The BUFFERED and AV_LEGEND attribute values are based on ROBUFF_COD values. BUFFERED decodes the ROBUFF_COD field. AV_LEGEND is a classification of ROBUFF_COD values. The BUFFERED and AV_LEGEND fields were populated though table joins to lookup tables. These values were not manually entered.

Positional Accuracy

Accuracy of the positional aspects of the data.

Horizontal accuracy report: When printed and displayed at 1:24,000 scale, this data can be considered to come close to complying 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. The buffered road lines are software generated from the Roads and Trails layer, which complies with this horizontal accuracy standard, and when displayed at 1:24,000 scale, the buffered road lines line up with the black lines edging the roads on the USGS 7.5 minute topographic quadrangle maps.

Process Step 3

Process description: Buffered Roads layer creation - Using ESRI ArcInfo software, the paved buffered roads and unpaved buffered roads layers were merged into a single ArcInfo coverage. By creating temporary polygon features to programmatically identify and delete the half round ends of paved roads inside (intersecting) unpaved buffered roads and half round ends of paved roads inside (intersecting) upaved buffered roads, continuously smooth patterns of buffered lines for paved and unpaved roads were generated. These line features retained original ROBUFF_COD attribute values of 1 or 2 to distinguish paved from unpaved roads.

Process Step 5

Process description: Attribute enhancements - BUFFERED and AV_LEGEND attributes were changed from storing upper case values (e.g. PAVED, UNPAVED) to both upper and lower case values (e.g. Paved, Unpaved). Using Arc Macro Language (AML), an automated process (MAKECOVER.AML) was developed to maintain consistent attribute values by programmatically joining lookup data tables to decode numeric code fields.

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

Online linkage: http://www.esri.com/metadata/esriprof80.html

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.
