Ocean polygon from Mount Desert Island shoreline out to
the extent of the MDI municipal jurisdoction.
The data set was created to define the salt water bodies 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 ocean area around MDI.
Users will need Arc/Info, PC Arc/Info, or ArcView software to use the data.
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.
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 "seperated 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 seprate data layers were created. Data layers were
clipped to the extents of the Mount Desert Island Municipal Town
boundaries. Data processed by COA GIS Lab. There was one revision.
Scaled proof plots were produced and checked for accuracy against USGS
24k paper quadrangles. Data was reviewed in ArcView prior to
documentation.
