Title: Connectcut Eelgrass Beds 2006 Poly
Originators: USFWS NWI Region 5
Publication date: Unknown
Data type: vector digital data
Data location: http://www.ct.gov/dep
Description
A characterization of the data, including its intended use and limitations.
Abstract: 
This data layer was created by the USFWS National Wetlands Inventory, Region 5.  Delineations of 2006 eelgrass beds were completed on the eastern Connecticut shoreline to the Rhode Island border.  Fisher Island, Plum Island, and the northern shore of Long Island, New York were also included in this work.  Spring 2006 True Color aerial photography was taken at a scale of 1:20,000 and used for detemining location and delineation of eelgrass beds.  Extensive field work was conducted by the USFWS Region 5 Southern Coastal Zone program in September, October and November, with 290 field sites. The 2006 photography was scanned and geo-rectified using 2004 ADS 1/2 meter true color imagery.
Purpose: 
This dataset was developed for an ongoing eelgrass monitoring of the Long Island Sound.  Funding was provided by the EPA, Region 2.

Process Step 1
Process description: 
The 2006, 1:20000 true color photography was scanned and geo-rectified to ADS 2004 true color 1/2 meter resolution imagery for Connecticut, and 1-ft resoluton  true color 2004 New York State imagery.  The 2002 eelgrass datalayer was used as a base, and polygonal data was added, subtracted or adjusted to reflect what was identified on the newer imagery.  Field work was completed using a USFWS research vessel, and USFWS personnel.  Two hundred and ninety sites were checked and documented.  This information was converted to a point datalayer and used to adjust the original delineation.

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.

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.

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.
