NOAA Office for Coastal Management Coastal Inundation Digital Elevation Model: Pago Pago Weather Service Office (PPG WSO) - Tutuila

Description

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: https://www.coast.noaa.gov/slr This metadata record describes the Pago Pago Weather Service (PPG WSO) digital elevation model (DEM), which 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. This DEM includes the best available lidar known to exist at the time of DEM creation that met project specifications for the Pago Pago WSO, which includes the following islands in American Samoa: Tutuila, Aunu'u, Ofu, Olosega, Tau, and Rose Atoll. The DEM is derived from the following source. 1. 2012 American Samoa Lidar - acquired by NOAA and partners Hydrographic breaklines were delineated from LiDAR intensity imagery generated from the LiDAR datasets. The final DEM is hydro flattened such that water elevations are less than or equal to -0.5 meters. The DEM is referenced vertically to the American Samoa Vertical Datum of 2002 (ASVD02) with vertical units of meters and horizontally to the North American Datum of 1983 (PACP00). The resolution of the DEM is 3 meters. The spatial information section in this metadata may indicate NAD83(PA11) horizontally because the Inport metadata system doesn't know PACP00.
