Description:
Abstract:
This is a polygon GIS layer background of the U.S. states counties
bordering the Long Island Sound study area.
Purpose:
The purpose of this data layer is to provide a broad and general reference
of the U.S. land mass surrounding the Long Island Sound study area. It
provides a regional overview of the U.S. northeast region and contains
all six New England states and 3 Mid-Atlantic states.
Supplemental_Information:
This data layer is a subset of a data layer provided by Environmental Systems
Research Institute, Inc (ESRI). Though its coastline is very coarse, it
provides a general reference for the individual U.S. lands surrounding
the Long Island Sound study area. It has been edited from the original
ESRI data set to eliminate several of the census attributes contained in
the original dataset table. The user wishing the full, unedited dataset
should contact ESRI or refer to the data provided by ESRI with their software
installations. Additionally, since the coastline is very coarse, overlaying
the medium resolution data layer, cst27, to this data set shows a number
of errors in the accuracy of the coastline in this data layer. It is used
and included here as a simple and quck way to provide a visual of the US
land body for the ArcView project views.
