The erosion-sites data layer is part of a Statewide GIS Analysis and Mapping of the Geologic Conditions Contributing to Eroding Terrace Escarpments, Project #03-02 of the Nonpoint Source Management Grant Program, funded under Section 319 (h) of the Federal Clean Water Act, and administered by the Connecticut Department of Environmental Protection.
Description
A characterization of the data, including its intended use and limitations.
Abstract:
Connecticut Erosion Sites is a site specific, point feature-based layer developed at 1:24,000-scale that includes decriptive information regarding the character of the erosion (severity, slope, geologic factors) at selected locations through out the state. The layer is based on information collected and compiled during October-December, 2005 while field testing the applicability of the Erosion Susceptilibity layer developed as part of Project #03-02 Statewide GIS Analysis and Mapping of the Geologic Conditions Contributing to Eroding Terrace Escarpments. The layer represents conditions at a particular point in time. The layer includes 83 locations and descriptive attributes (site name, severity of erosion, description, etc) as well as attributes from a spatial join with merged soils and quaternary geology layers.  Features are point locations that represent the selected study areas within the state; it is NOT a comprehensive inventory of erosion locations.  Data is compiled at 1:24,000 scale. This data is not updated.
Purpose:
Connecticut Erosion Sites is a site specific data layer developed at 1:24,000-scale. The purpose of this layer is show locations and provide desriptions of erosion sites used to confirm the applicability of the draft erosion suscepibility map. Erosion sites were inventoried in selected areas of the state wide study area. This map should be used in conjunction with the final 1:24,000 scale Erosion Susceptibility layer and other documents developed for the Project #03-02: Statewide GIS Analysis and Mapping of the Geologic Conditions Contributing to Eroding Terrace Escarpments.  The objective of this project is to identify the geologic conditions that lead to eroding terrace escarpments throughout the state. This layer is part of an information package that can be used as a planning and management tools by state and municipal officials. Not intended for maps printed at map scales greater or more detailed than 1:24,000 scale (1 inch = 2,000 feet.)

+ 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:
Point features conform to the following topological rules. Points are single part. There are no duplicate points. Points do not overlap. Establishment of logical consistency was performed by the State of Connecticut, Department of Environmental Protection using ESRI ArcGIS software to manually create and control feature topology in shapefile format. No automated procedures or tests were performed to guarantee desired topology other than visual inspection.
Completeness report:
The completeness of the data reflects the feature content of the data sources, which include the FIELD DATA SHEETS for the project. The erosionsites layer is complete in the sense that it accurately reflects the contents of the Erosion sites field information available at the time the State of Connecticut, Department of Environmental Protection created the layer. However, compared to current conditions, the erosionsites layer is incomplete. This data is not updated.
Attribute Accuracy
Accuracy of the identification of data entities, features and assignment of attribute values.
Attribute accuracy report:
The erosionsites layer retains the feature types and information identified by the State of Connecticut, Department of Environmental Protection and obtained from the data compiler. All attributes have valid values. Values are within defined domains. The accuracy test for the attribute values was conducted by comparing the information presented in the source data with 1:24,000-scale field sheets and interactive displays of the data on a computer graphic system. These check plot maps and computer displays depicted and labeled the erosionsites features in different colors based on values for comparison with the original data source.  AV_LEGEND and IMS_LEGEND are broad classifications of erosionsites features.  AV_LEGEND, and IMS_LEGEND were not manually entered. These additional fields were populated by calculating values equal to existing fields.  Erosionsites features were manually selected and populated with descriptive attributes values to (uniquely) identify and describe individual features. Attributes respresenting geologic and soils conditions for each sites, and erosion category were populated by spatial join. 
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. Some feature locations were interpolated from the transporation features, surface water features, elevation contours, buildings, and built-up areas depicted on USGS 7.5 minute topographic quadrangle maps. Other feature locations were derived from GPS coordinates; their horizontal precision exceeds the map standard.Typically, the Trimble Pro XR collects data with the PDOP set to 6.0 and the S/N set to 10.0 the standard error of the collected data is less than 1 meter, so the 95% confidence is on the order of 2 meters.

Point features represent approximate positions for linear or large area objects or observations that are transient, variable or temporal in nature. 
 
Some features are accurately positioned because GPS-based coordinates were collected at the actual location of the site in the field, and other features are less accurately positioned because the site represents a large area which was interpolated from topographic quadrangle maps.

Process description:
Feature digitizing and attribution (heads up digitizing method) - Using ESRI ArcView 3 software, features appearing on the source map were manually digitized on the screen (heads-up digitizing) at display scales greater than 1:24,000 using USGS 7.5 minute topographic quadrangle maps displayed in the background for reference. Individual features were digitized based on topographic base information. Features were assigned attribute values based on information shown on the field maps. Feature location and attribute accuracy was visually checked and inspected by symbolizing and labeling features according to attribute value on the computer screen and comparing this information to the orginal source data.

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.
