GCE-LTER Data Set Summary

Title: Cross-site comparison of historical trends in marsh change at three LTER sites: GCE, VCR, and PIE.
Abstract: The data provided here are shapefiles which were generated from digitizing historical maps and aerial photographs for a cross site comparison of changes in marshes at the Plum Island Ecosystem (PIE), Virginia Coast Reserve (VCR), and Georgia Coastal Ecosystems (GCE) Long Term Ecological Research (LTER) sites. This dataset includes shoreline shapefiles digitized for 3 time intervals at each site: 1930s/40s, 1950s/70s, and 2013 as well as a table of results from the shoreline change analysis. Centerlines for all the channels were generated from the shoreline shapefiles and are attributed with Strahler (1965) channel order and sinuosity. Additionally, this dataset includes shapefiles of important features (channels, upland, ponds, tidal flats) digitized for each of three sites at three time intervals.
