This dataset provides a shorelines (VBI-allshores.zip) and set of area polygons (VBI-allislands.zip) delineated from historical NOS t-sheet (1851-1962) and USGS satellite imagery (1994-2017) spanning the barrier islands of the Eastern Shore of Virginia in multiple GIS data layers.
The VBI-allshores dataset provides a comprehensive set of historical NOS t-sheet (1851-1979) and satellite imagery (1980-2017) shorelines spanning the islands south of Assateague along the Virginia Eastern Shore in a single GIS data layer. This shoreline dataset compliments and overlaps other VCRLTER shoreline datasets for the Virginia barrier islands that contain historical shorelines derived from a combination of sources, including photointerpretation of aerial photos, satellite imagery, and LiDAR assessments (from USGS, NOAA, VITA-VGIN-VBMP, and others).
