    Legacy Historical Shorelines by Years

    Metadata Updated: January 3, 2026

    This Legacy Historical Shorelines is a subset of the Maryland Historical Shorelines data set with 5 counties being excluded from the shorelines which are Anne Arundel, Balimore, Calvert, Harford and Prince George's County. The remaining counties have these digital shoreline vectors which are used to overlay orthophoto base map rasters of the Maryland shoreline and show historical shoreline locations in relation to the Rates of Change (ROC) erosion level transects data. Acquired as part of multi-year Shoreline Changes mapping project to show erosion and other shoreline shifts along Maryland's Chesapeake Bay and tidal tributaries. The newer county shoreline data can be viewed using the "Limited ROC Shorelines by Decade" map layer and this Legacy Shoreline layer will be replaced by the Limited ROC Shorelines by Decade as counties are updated over time.
