Description:

Abstract:

This data release provides flooding extent polygons based on sea-level rise (SLR) water levels for the coast of American Samoa's most populated islands of Tutuila, Ofu-Olosega, and Ta'u. Digital elevation models were used to predict SLR flooding extents for +0.25 m, +0.50 m, +1.00 m, +1.50 m, +2.00 m, and +3.00 m SLR scenarios.

Purpose:

These flood extent files were created to evaluate coastal flooding in the most populated American Samoan Islands of Tutuila, Ofu-Olosega, and Ta'u due to climate change influenced SLR. The data are intended to help identify areas where management and/or restoration could potentially help reduce the risk to, and increase the resiliency of, the coastal communities in the populated in American Samoa. The data can be used with geographic information systems (GIS) software for research purposes.

Supplemental_Information:

Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government.
Although this Federal Geographic Data Committee-compliant metadata file is intended to document the dataset in nonproprietary form, as well as in Esri format, this metadata file may include some Esri-specific terminology.

Process_Step:

Process_Description:

All extracted elevation DEMS for each scenario of sea level rise were converted from a raster to polygons in ArcPro. Each elevation raster was multiplied by zero than set to a value of 1. These new rasters were then converted to polygons using the value one to group adjacent areas. The resulting shapefiles were the outlines denoting the extent of flooding for each of the six SLR scenarios (0.25, 0.5, 1.0, 1.5, 2.0 and 3.0 m) for the coast of American Samoa's most populated islands of Tutuila, Ofu-Olosega, and Ta u. Shapefiles were manually inspected to remove any areas that could not immediately be seen to the result of inundation. Final shapefiles were separated by island (Island_SLR_extents*.zip) for file-size considerations.

Overview_Description:

Entity_and_Attribute_Overview:

shapefiles contained in this part of the data release include projected flood extents in the following format SLRASamoa_[Island] _[SLR scenario]_extent.shp, where [SLR scenario] = one of the 6 SLR scenarios modeled (025cm, 050cm, 100cm, 150cm, 200cm, 300cm), Files are grouped by island, containing all SLR scenarios. For example, Tau_SLR_extents.zip, contains all outputs for Ta u, within which SLR Tau_300_extent.shp illustrates the flood extents for a SLR of 300 cm.
