Description

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

Abstract:

This is an index of the 3.75-minute quarter quadrangle areas that cover the State of Connecticut. There are four 3.75-minute quarter quadrangles per 7.5-minute quadrangle area. The index includes a polygon feature for each 3.75-minute quarter quadrangle area. Note that the boundaries of the polygon features in this layer DO NOT correspond exactly with the quadrangle boundaries published on the topographic quadrangle maps because the polygon feature boundaries are based on the Connecticut State Plane Coordinate System, North American Datum of 1983 (NAD83) and the boundaries on the quadrangle maps are base on the Connecticut State Plane Coordinate System, North American Datum of 1927 (NAD27). This index was generated by mathematically projecting the 3.75-minute latitude and longitude quarter quadrangle corner coordinates to Connecticut State Plane Coordinate System, NAD83.  It represents a true NAD83 index of 3.75-minute quadrangle areas. Polygon attribute information is comprised of codes to uniquely identify individual quarter quadrangle areas. This is static information that is not subject to change.

Purpose:

Use this layer as an index to the set of USGS Digital Orthophoto Quarter Quadrangles published by the U.S Geological Survey, in cooperation with U.S. Department of Agriculture and the Connecticut Department of Environmental Protection. The USGS Digital Orthophoto Quarter Quadrangle (DOQQ) photos for Connecticut were published at 1:12,000 scale and are available from the State of Connecticut, Department of Environmental Protection.

+ 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:

Use the QUAD_NO attribute to distinguish individual USGS topographic quadrangle areas. Use the QUAD_SEC attribute to distinguish between the four quadrants (NE, NW, SE, and SW) for each topograhic quadrangle area. Combine (concatinate) the QUAD_NO and QUAD_SEC attribute values to uniquely identify quarter quadrangle polygon features. For example, the four quarter quadrangle polygon features for the Clinton quadrangle (quadrangle number 98) are 98NE, 98NW, 98SE, and 98SW. Use the Connecticut Quadrangle Flag attribute (CTQUAD_FLG) to select quadrangles that cover the geographic area for the State of Connectictut with the following expression - CTQUAD_FLG = "T".

+ 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:

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. 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 0 (zero) feet (dangle length).

Completeness report:

The degree of completeness is based on the extent to which the data covers the geographic area of the State of Connecticut. The layer is complete because it includes four 3.75 minute quarter quadrangle polygon features for all of Connecticut 7.5 minute quadrangle areas, including areas defined by 7.5 minutes of latitude and longitude where the USGS published 1:24,000-scale topographic quadrangle maps and areas of 7.5 minutes of latitude and longitude entirely covered by water (in Long Island Sound) where the USGS did not publish 7.5 minute topographic quadrangle maps.

Attribute Accuracy

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

Attribute accuracy report:

The USGS 3.75 Minute Quarter Quadrangle Index layer depicts the quarter quadrangle areas for the 7.5 minute USGS topographic quadrangle maps as polygon features with boundaries originally based on a NAD83 horizontal datum rather than NAD27 used by the USGS to publish the topographic quadrangle maps. All attributes have valid values. Values are within defined domains. The accuracy test for the QGNO, QUAD_NO, QUAD_SEC, and CTQUAD_FLG attribute values were conducted by manually entering and visually inspecting and verifying values. The QUADRANGLE attribute is the English language equivalent of (decodes) the QUAD_NO field values and was populated by joining the feature attribute data table to a lookup data table with QUAD_NO used as the relate key field. This lookup data table contain records with information that account for the unique occurrences of QUAD_NO.

Positional Accuracy

Accuracy of the positional aspects of the data.

Horizontal accuracy report:

The horizontal positional accuracy of this data complies with 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.

Process step information

Process Step 1

Process description:

The polygon boundaries for this layer were not manually digitized but rather mathematically generated by projecting the latitude and longitude coordinate values that define the corners of the 3.75-minute quarter quadrangle areas to the Connecticut State Plane Coordinate System, North American Datum of 1983 (NAD83). The latitude and longitude coordinates of the four corners for each quarter quadrangle formed the end points of four line features that bound each polygon feature. These lines of latitude and longitude spaced at 3.75-minute intervals were generated for the purpose of creating quarter quadrangle polygon features.

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.
