The
Strategic Environmental Assessments (SEA) Division of
the National Oceanic and Atmospheric Administration
(NOAA) has created a digital vector data set of the
contiguous United States shoreline. It is compiled from
hundreds of NOAA coast charts comprising over 75,000
nautical miles of coastline. The
digital vector data set is divided into four major
regions consisting of West Coast, East Coast, Gulf
of Mexico Coast, and Great Lakes Coasts, each of which
has multiple sub-regional files. This data was then
converted toTobin format and edge-matched between
available scales to make a single, contiguous shoreline.
The conversion process maintains the integrity of
NOAA's Medium Resolution Digital Vector Shoreline
and provides an accurate spatial representation of
the United States shoreline.
NOAA compiled the shoreline
data directly from the most up-to-date coast charts
available at the time (1988-1992). The digital shoreline
of Florida was obtained from the state and not recreated
by the SEA because the shoreline data was created
from NOAA nautical charts.
• Derived from National Oceanic and Atmospheric
Administration’s (NOAA) digital
vector data set, which was derived from
hundreds of NOAA coast charts.
• Tobin provides an accurate spatial representation
of the United States shoreline.
• The shoreline data is available as ARC/INFO
formats, in esport (e00) or shapefile
• Tobin provides the only contiguous United
States Shoreline product.
The average mapping scale for the entire Medium Resolution
Digital Vector Shoreline is approximately 1:70,000.
The shoreline data is available as ARC/INFO coverages
in an export file (e00 file) or shapefile formats.
• West Coast
• East Coast
• Gulf of Mexico Coast
• Great Lakes Coasts.
