Service Description: The dynamic nature of coastal barriers such as Assateague Island is a defining characteristic, influencing nearly every aspect of their ecology. Fundamentally disturbance driven systems, barrier islands and their endemic biota are continually shaped by physical forces on a time scale vastly accelerated in comparison to mainland systems. Because of the rapid pace and scope of change, long term monitoring is crucial towards understanding natural barrier island conditions as well as anthropogenic influences. This appended shoreline dataset was created to aid in data use and distribution. Shorelines are also stored and available as individual line shapefiles, which are available through contacting the NCBN data manager(dennis_skidds @nps.gov).

Description: These data represent a series of mean high water shorelines collected at Assateague Island National Seashore (ASIS), appended into one personal geodatabase. The features have been assembled / collected in support of the Northeast Coastal & Barrier Inventory and Monitoring Network's Ocean Shoreline Position Monitoring Program. The shoreline surveys are collected using a Trimble ProXR, GeoXT, or GeoXH GPS receiver mounted on an ATV, and range in dates from August of 1993 to the most recent updated survey. Depending on the time of year and intended purpose, some surveys contain ocean, inlet and bay shorelines, while some surveys only contain ocean shorelines. Additionally, some surveys collected prior to 2003 do not contain FGDC-compliant metadata records.
