Description
A characterization of the data, including its intended use and limitations.
Abstract:
Historic Eelgrass Bed Polygons is a 1:24,000-scale, polygon feature-based layer that depicts the locations of historic eelgrass beds (Zostera marina) in Long Island Sound and the Niantic River, as well as in other bays, harbors and waterbodies in Connecticut's coastal area.  It also includes several points located along the north shore of Long Island.  There are a total of 52 polygon features, all of which (except the Long Island points), are located within or east of the Niantic River.  This layer can be used with Historic Eelgrass Points.   This layer does not represent current conditions.  Rather, it depicts historic eelgrass bed locations that were observed and defined either cartographically or narratively over the course of many years and from various sources.  The dates of each source's data collection are noted in the attribute table.  Feature locations are inexact.  Because of the variety of source maps and methods used for their automation, this information should be considered to have limited spatial accuracy and is appropriate for general uses only.  The data was taken from maps of various scales and projections that were drawn between 1905 and 1996.  These maps were reduced to approximately 1:24,000 scale and adjusted for best fit; eelgrass areas were redrafted onto USGS Topographic Quadrangle maps for digitizing.  In order to create a single polygon coverage, areas were considered to represent a maximum extent of eelgrass beds.  This layer was published in 1997 and is not updated.  
Purpose:
Eelgrass Historic Beds is 1:24,000-scale data.  It depicts the location of eelgrass beds that existed historically at dates specified in the attribute data, resulting from a literature review that yielded mapped data.  Use this layer with other 1:24,000-scale map data only, to provide a general indication of historical eelgrass distribution.  This layer can also be used with the following related layers:  Historic Eelgrass Points, Observed Eelgrass, Potential Eelgrass, and Eelgrass Sample Points.  This layer is not intended for maps printed at map scales greater or more detailed than 1:24,000 scale (1 inch = 2,000 feet.)
Supplemental information:
The label points generated by ArcInfo software in the creation of the eelgrass polygons in this layer were subsequently used in the creation of the Historic Eelgrass Points layer, which includes additional sample points derived by GPS data collection methods.  Refer to that layer for more information.

+ 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:
Historic data is assumed to be complete for the set of literature reviewed; however, additional historic references to eelgrass locations may exist. The data is not presumed to be a comprehensive representation of pre-1996 eelgrass distribution.  Refer to Source Information for a list of historic references for this data.
Completeness report:
The completeness of the data reflects the feature content of the data sources, which include the sources as noted in the Source attribute in the data table.  These sources include paper maps, reports and memoranda.  The Historic Eelgrass Beds layer is complete in the sense that it accurately reflects the contents of the source information available at the time the State of Connecticut, Department of Environmental Protection created the layer.  This data is not updated.
Attribute Accuracy
Accuracy of the identification of data entities, features and assignment of attribute values.
Attribute accuracy report:
Attributes were derived from literature review and checked by the compiler and other reviewers (or co-authors) in a consistent manner. Since attributes were derived from multiple sources the accuracy of reporting or consistency of observations is likely to vary.
Positional Accuracy
Accuracy of the positional aspects of the data.
Horizontal accuracy report:
Because of the variety of the source information and the methods used for their compilation, this data should be considered to have very limited spatial accuracy and is appropriate for general uses at no greater than 1:24,000 scale.  Mapped locations were made to fit the 1:24,000 scale USGS topographic quadrangle maps.   General locations are based on text descriptions of varying detail and may be representative of a very general area such as a large cove or embayment.

Process step information
Process Step 1
Process description:
Polygons represent some previously mapped distributions of Zostera marina (eelgrass).  All were digitized off 1:24,000 USGS topographic quadrangles.  Maps of various scales and projections (some unknown) in Knight and Lawton, 1974; Welsh, 1980; Brown, 1996; and Johnson and York, 1915 were reduced to approximately 1:24,000 scale and adjusted for best fit; eelgrass areas were redrafted onto quadrangles for digitizing.  The same process was used for original maps from the Northeast Utilities Report, except the maps were either enlarged or already close to 1:24,000 scale.  In order to create a single polygon coverage, areas were considered to represent a maximum extent of eelgrass beds - the large area on the western side of Jordan Cove is a combination of the overlapping distributions mapped in 1974 and 1985.  Juliana Barrett's compilation maps were drawn on 1:24,000 scale quadrangles; polygons originating from that compilation were digitized as is.  Because of the variety of the source maps and methods used for their automation, this coverage should be considered to have limited spatial accuracy and is appropriate for general uses only.  Note that the label points from all polygons were put into the eelhistx datalayer - a point coverage of historic occurrences of eelgrass for which the literature did not contain mapped areas.  This digital compilation is based for the most part on a literature review by Ron Rozsa (CT DEP) and Ruth Linden / Charles Yarish (UCONN Stamford), and Mary DiGiacomo-Cohen (LISRC) and is not presumed to be a comprehensive representation of the pre-1993 distribution of Zostera marina.  

Using ESRI ArcInfo software, features were digitized by registering the source map (Source 2) to the digitizing tablet and using the crosshairs of the digitizer's mouse to manually capture the geometry (location) of features drafted on the map. The corners of the USGS 7.5 minute topographic quadrangle maps are used as registration points and are depicted on the source map. The source map was registered to the digitizing tablet by digitizing (entering) the locations of four quadrangle corner registration points shown on the map. ArcInfo software compared the values of the digitized coordinates with the actual (true) values for the quadrangle corner (tic) features.

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.
