The index coverage includes the south shore of Long Island from eastern part of the Borough of Queens to the eastern shore of Shinnecock Bay at the Village of Southampton.
Coverage also extends inland to roughly correspond with the surface run-off watershed.
Covered area is approximately 500 square miles. The index was created to provide a data file linked to the detailed two foot tile digital orthophotography file names for the South Shore Estuary Reserve Plan. Index available for direct download from NYS GIS data cooperative. There is a file naming idiosyncrasy. The index departs from the pattern of numbering for eight of the 2 foot detail image tiles.
