Assateague Island National Seashore (ASIS) Shoreline Position Change Monitoring Data Package - 2025
These data represent a series of mean-high water shorelines collected at Assateague Island National Seashore (ASIS), appended into one spatial dataset. The features have been assembled / collected in support of the Northeast Coastal & Barrier Inventory and Monitoring Network's Ocean Shoreline Position Monitoring Program. Surveys along the ocean shoreline were collected by driving a 4-wheel drive vehicle or walking at a relatively constant speed along the identified high tide swash line. For the purposes of this monitoring program, the actual ocean "shoreline" was defined as the average position of the most recent high tide, evidenced by the obvious wet/dry sand line or deposited wrack. The GPS/GNSS receiver was configured to record positions at a very short interval (at least 1 position every 10 meters) for the best representation of the shoreline position. 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. This dataset contains shoreline features collect between Winter of 1994 and Spring 2025.
