* » Abstract |
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. |
* Purpose |
The NOAA Office for Coastal Management has developed high-resolution digital elevation models (DEMs) for use in the Office's Sea Level Rise And Coastal Flooding Impacts internet mapping application. These DEMs serve as source datasets used to derive data to visualize the impacts of inundation resulting from sea level rise along the coastal United States and its territories. |

Horizontal Positional Accuracy |
The DEM is derived from the source data. Horizontal accuracy testing is not performed on the DEM. Source data assumed to meet 1 meter horizontal accuracy. |
Vertical Positional Accuracy |
The DEM is derived from the source data. Vertical accuracy is not tested on the DEM. Project specifications require all source data used in constructing the DEM to meet FEMA Specifications for Flood Hazard Mapping. |

Completeness Report |
A visual qualitative check was performed to ensure data completeness. All available data known at the time of DEM creation that meets project specifications has been used to develop the DEM. Known data gaps may exist where coverage was incomplete. |
Conceptual Consistency |
Data covers the project area which includes the islands of the US Virgin Islands of St. Croix, St. John and St. Thomas. Elevation data was checked for anomalous elevation values outside the expected range. |

1. Contractor developed hydro-breaklined DEMs in img format were created from the 2013 NOAA Topographic Lidar for the U.S. Virgin Islands data set. These DEMs were at a 1m cell size, referenced to the Virgin Islands Vertical Datum (VIVD09), and in vertical units of meters. 2. The DEMs were reviewed in Global Mapper and areas that should have been hydro-flattened were fixed. 3. All DEMs for the entire project area were loaded into Global Mapper for a final review. The constituent DEMs were then checked to ensure complete coverage within the project area. They were then mosaiced together, resampled to 3 meters and reprojected to the NAD83 geographic coordinate system. |
