NOAA Office for Coastal Management (OCM) Coastal Inundation Digital Elevation Model: U.S. Virgin Islands

These data were created as part of the National Oceanic and Atmospheric Administration Office for Coastal Management's efforts to create an online
mapping viewer called the Sea Level Rise and Coastal Flooding Impacts Viewer. It depicts potential sea level rise and its associated impacts
on the nation's coastal areas. The purpose of the mapping viewer is to provide coastal managers and scientists with a preliminary look at sea
level rise (slr) and coastal flooding impacts. The viewer is a screening-level tool that uses nationally consistent data sets and analyses.
Data and maps provided can be used at several scales to help gauge trends and prioritize actions for different scenarios. The Sea Level Rise
and Coastal Flooding Impacts Viewer may be accessed at: http://www.coast.noaa.gov/slr
This metadata record describes the digital elevation model (DEM) for the U.S. Virgin Islands of St.Croix, St. John, and St. Thomas. This DEM
is a part of a series of DEMs produced for the National Oceanic and Atmospheric Administration Office for Coastal Management's Sea Level Rise and
Coastal Flooding Impacts Viewer described above. The DEMs created for this project were developed using the NOAA National Weather Service's Weather
Forecast Office (WFO) boundaries. The U.S. Virgin Islands DEM includes the best available data known to exist at the time of DEM creation, that met
project specifications for the U.S. Virgin Islands in the San Juan, PR WFO. This includes the coastlines of St. Croix, St. John, and St. Thomas.
This DEM was derived from the 2013 NOAA Topographic Lidar for the U.S. Virgin Islands. A hydro-flattened DEM created from this data was provided
by the contractor as a deliverable.
The DEM is referenced vertically to the Virgin Islands Vertical Datum (VIVD09) with vertical units of meters and horizontally to
the North American Datum of 1983 (NAD83). The resolution of the DEM is approximately 3 meters.
