Title: Shellfish Management Areas, Northeastern United States, 2013
Contributors:- Polygon data
- 2013
Summary: This polygon shapefile represents shellfish growing and classification areas for states in the northeastern U.S. including Connecticut, Maine, Massachusetts, New Hampshire, New York, and Rhode Island. Each state has their own method of classifying shellfish areas and these were evaluated in order to create a comprehensive classification system throughout the northeast region. The classification scheme used in this regional dataset is adapted from the National Shellfish Sanitation Program (NSSP) Guide for the Control of Molluscan Shellfish. Each feature includes information on the area name, classification type, state, source of the data, layer name from the data source, and the original state classification scheme. Additional fields which contained further information for individual datasets but did not conform to this characterization were not included. The Northeast Ocean Data Portal working group is continuing to work with shellfish coordinators in each state to improve the representation of these management areas and the timeliness of regional datasets. The data user is encouraged to read this and the metadata of each individual states’ source data carefully, as attribute details, and timeliness are not necessarily consistent among datasets used to develop this layer. Details of each state’s data source are described in the data processing section. The purpose of this dataset is to assist in ocean planning activities in the Northeast by representing the shellfish management and classification areas for the northeastern United States. Data represented here are from the most recent editions up to the dataset publication date. Data at this scale is suitable for use in generalized studies and local planning. Maine. Department of Marine Resources. (2013). Shellfish Management Areas, Northeastern United States, 2013. Northeast Ocean Data. Available at: http://purl.stanford.edu/qp739ty3462. Users must assume responsibility in determining the usability of this data for their purposes. Digital maps retain the accuracy of their source materials. The best use of data mapped at scales of 1:500,000 and 1:250,000 is in statewide planning and studies; at 1:100,000 in regional planning and studies; at 1:62,500 and 1:24,000 in detailed studies and local planning; and at 1:12,000 and 1:5,000 or larger scales in parcel level studies and detailed local planning. In the use of Maine GIS data, please check sources, scale, accuracy, currentness and other available information. Please confirm that you are using the most recent copy of both data and metadata from the Maine GIS Data Catalog. This layer is presented in the WGS84 coordinate system for web display purposes.
