Description:

Abstract:

The National Assessment of Coastal Change Hazards project aims to understand and forecast coastal landscape change. This dataset consists of delineated coastal cliff transects that may be used to assess the hazard posed by eroding coastal cliffs on the islands of Puerto Rico, Culebra, and Vieques. The delineation of cliff tops and toes can be used as an input into cliff hazard metrics and to measure overall cliff changes over time. Cliff tops and cliff toes were identified along three-dimensional (3D) transects using the Cliff Feature Delineation Tool (Seymour and others, 2020), which assigned coordinate locations (X, Y, Z) of cliff features over a 140,244-meter (m) stretch of the Puerto Rican coastline at 10-m intervals and output them as either polyline (cliff transects) or point (cliff top or toe) shapefiles. Feature delineation was preformed using post-Hurricane Maria (landfall was September 20, 2017) rasterized topobathy lidar elevation data collected by the U.S. Army Corps of Engineers and published by the National Oceanic and Atmospheric Administration National Centers for Environmental Information (2018) as bare earth digital elevation model (DEM) files. The delineation tool (Seymour and others, 2020) was used to generate 3D point features in Esri ArcGIS shapefile format representing the cliff transects, these files should be opened in a 3D geographic information system (GIS) viewer.

Purpose:

To provide data on the morphology of coastal cliffs in Puerto Rico and surrounding islands offshore of the east coast. Additional survey and data details are available from the U.S. Geological Survey Coastal and Marine Geoscience Data System (CMGDS) at https://cmgds.marine.usgs.gov/fan_info.php?fan=2018-307-DD.

Process_Step:

Process_Description:

The Cliff Feature Delineation Tool (Seymour and others, 2020) was used to extract cliff top and toe points at 10-m alongshore intervals wherever coastal cliffs were present along the Puerto Rico coastline. For more information on how cliff top and toe features were extracted, please see USGS Open-File Report 2020–1070 (Seymour and others, 2020). The process of delineating the cliff transect features began by using a 2018 post-Maria bare earth topobathy lidar DEM as the elevation input. The DEM downloaded from the NOAA NCEI site was a 32-bit GeoTiff raster image with a 1-m grid spacing. Horizontal positions were provided in geographic coordinates referenced to the World Geodetic System of 1984 (WGS84) Universal Transverse Mercator (UTM) Zone 20 North (20N) and vertical positions were referenced to the Puerto Rico Vertical Datum of 2002 (PRVD02). Baseline inputs were represented by Esri ArcGIS shoreline vectors or generated by the Cliff Feature Delineation Tool. A user parameterized tool iterated separately for regions of a cliff that had relatively similar morphology, in all cases following rules outlined in the Seymour and others (2020) user guide. The final file, CliffTransects_PuertoRico.shp, was output with horizontal positions and elevations remaining in their native projected coordinate reference systems. Outputs went through a QA/QC process in ArcGIS Pro and were edited, if needed.
