Service Description: The Assateague Island geomorphological map is the spatial portrayal of the evolution of the barrier island system that developed from a series of several discrete ancestral units through its consolidation into a continuous barrier. It has topographical features that show a series of accretionary ridges and swales that record inlet creation and closure. The Assateague Island geomorphological map consists of 16 panels, covering the island from Ocean City Inlet to the Maryland-Virginia border. One set of panels portrays the distribution of geomorphological features without hillshade and the other incorporates hillshade in its depiction.

Description: GIS data for the "Development of a Geomorphological Map of Assateague Island National Seashore" in 2016. Assateague Island National Seashore (ASIS) is one of 270 National Park System units designated to have a digital geological/geomorphological map and an accompanying Geological Resources Inventory report. These products are intended to provide a valuable synthesis of the physical makeup of the site and assist in applying appropriate strategies in the management of its natural and cultural resources. Under the sponsorship of the NPS Geological Resources Division, an early version of an ASIS geomorphological map was produced by Morton et al. (2008), a hydrogemorphological map was generated by Krantz (2010), and a report by Schupp (2013) described the geological resources and the evolution of the surface configuration. See the full NPS report available on irma.nps.gov.
