| Description |
These geospatial datasets correspond to the extraction of elements and their attributes related to the shoreline and back beach of eleven (11) municipalities in the northwest and north coasts of Puerto Rico (Rincón, Aguadilla, Isabela, Hatillo, Arecibo, Dorado, Vega Baja, Carolina, Loíza, Río Grande, and Luquillo). These data were generated as part of the "U.S. Geological Survey (USGS) Development of Coastal Change Capacity in Puerto Rico" project (Cooperative Agreement G23AC00551-02). Cartographic information is organized into eight data types for the purpose of analysis and monitoring of changes along selected municipalities of the northwest and north coast of Puerto Rico. The "Federal Emergency Management Agency-University of Puerto Rico at Río Piedras (FEMA-UPRRP) Post-María Beach Assessment" project, which the Coastal Research and Planning Institute of Puerto Rico (CoRePI-PR) team published in 2021 (FEMA-4339-DR-PR Grant No. 4339-0007p), served as the baseline for the creation of these datasets. This dataset modifies the techniques established by Barreto and others (2021), which integrates high-resolution image analysis, field data collection, and an assessment of the pre-existing conditions of the beaches using Geographic Information Systems (GIS) (FEMA-4339-DR-PR Grant No. 4339-0007p). The data types are as follows: 1) shoreline, 2) back beach, 3) beach edges, 4) beach polygons, and 5) beach transects (5-meters), 6) beach transects 2018 vs. 2022–2023, 7) lost transects and 8) beach displacement. In addition to providing shapefiles (.shp) with this data release, these data are packaged into a file geodatabase (.gdb) and ArcGIS Pro Map Package file (.mpkx) for enhanced visualization of the data.
