Abstract:
Shoreline of Mount Desert Island and islands of MDI municipal
towns. Created from USGS 24k DLG data representing mean high water or
high tide. Polygon data has area attributes and line data has length
attributes.
Data set was created to define the shore of Mount Desert Island and to
serve as a digital "base map" layer. Some local tax maps show
shoreline data, but this seems to be the most widely accepted
representation of the shoreline of MDI. More detail is needed for site
specific studies however.
The original 24k USGS DLG files were obtained by the National Park
Service for Acadia National Park. DLG files were converted to
Arc/Info coveraged by the NPS and provided to College of the Atlantic
under cooperative agreement between NPS and COA. Original covers,
hydrology and transportation, provided by the park contained all
features in two layers. shoreline, and other features, were "separated
out" using the DLG coding. This coding had many minor coding errors
such that covers did not have proper connectivity, so coding was
corrected in PC Arc/Info and thus separate data layers were
created. Data layers were clipped to the extents of the Mount Desert
Island Municipal Town boundaries. Boundaries digitized from USGS 24k
Quads.
This information was obtained from Federal Geographic Committee
metadata produced by Gordon Longsworth of the College of the Atlantic
and put into Nasa Directory Interchange Format by Cheryl Solomon.

Some local tax maps show shoreline data in more detail, but this seems
to be the most widely accepted representation of the shoreline of
MDI. More detail is needed for site specific studies such as those
examining individual land parcels or for island research.
