    • ASIS GPS Shorelines

    Metadata Updated: April 25, 2025

    These data represent a series of mean high water shorelines collected at Assateague Island National Seashore (ASIS), appended into one file geodatabase (1993-2022). Post-2022 surveys can be found on https://asis-nps.opendata.arcgis.com/. 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 sub-meter GPS receiver mounted on an ATV or UTV starting in August of 1993 continuing through present day. Shorelines are grouped in Feature Datasets by the season the data were collected. Depending on the time of year and intended purpose, some surveys contain ocean, inlet and bay shorelines, while some surveys only contain ocean shorelines.
