The Maryland Geological Survey (MGS) developed this shoreline feature class as part of a project to calculate updated rate of change information for Anne Arundel, Baltimore, Harford and Prince George's Counties. These 5 counties have specifics related to each for the shoreline erosion anaylsis and the details are designated within the metadata. This shoreline data set spans the time period 1932-2010, and was used as input to the U.S. Geological Survey (USGS) Digital Shoreline Analysis System (DSAS) v4.3 program to calculate long-term and short-term rates of change (erosion and accretion). |
