Hog Island, VA shorelines and upland/marsh boundaries 1852-2001

Digital outlines of Hog Island VA for: 1852, 1871, 1910, 1919, 1943, 1967, 1980, 1990 and 1993. The coverage-ID field contains a number that allow distinguishing marsh from upland areas (typically 1=marsh, 2=upland). There are also .jpg image files containing browse images for the coverages. /// Update: John Porter added 2001 based on digitization of a 10/15/2001 IKONOS satellite image. The high tide line was digitized on the beach based on the edge of the wetted sand. For the marsh, the marsh-lagoon border was digitized. The upland/marsh boundary is not included for 2001. Original shapefiles (one per year) are in NAD27 UTM 18N. Update2: Dave Richardson combined shapefiles for individual years into a single shapefile with YEAR added as a distinguishing attribute. CLASS was added as a text string to describe the value of ID (0=Water, 1=Marsh, 2=Upland, or 3=Upland+Marsh). Finally, data was reprojected from UTM 18N NAD27 to UTM 18N WGS84 and the Area and Perimeter values recalculated. This is now the most up-to-date version of this dataset, and supercedes  dataset VCR97037.
