Elevation Mapping of Critical Park Areas for Planning and Post- Future Storm Evaluation and Modeling – Fire Island National Seashore

Published by National Park Service | Department of the Interior | Metadata Last Checked: January 25, 2026 | Last Modified: 2018-02-09T00:00:00Z
This ArcGIS geodatabase contains all the raster and vector data layers associated with the elevation surveying and inundation modeling done for the project. The layers include: ground survey elevations for critical park areas, long-term benchmark locations and data (backbone sites), first floor elevation (FFE) surveys along with inundation risk, and SLOSH and ADCIRC inundation modeling outputs (water surface elevation grids). In addition, byproducts of the modeling are also included (water depth grids and polygons and dryland areas (SLOSH only)).
