American Samoa: Projected coastal flooding inundation depths for 0.00, +0.25, +0.50, +1.00-, +1.50-, +2.00-, and +3.00-meter sea-level rise scenarios (ver. 1.1, February 2025)

This data release provides flood depth GeoTIFFs based on sea-level rise (SLR) for the coast of the most populated American Samoa s most populated islands of Tutuila, Ofu-Olosega, and Ta'u. Digital elevation models were used to extract SLR flooded areas at 10-m2 resolution along the coastlines for 0.00 m, +0.25 m, +0.50 m, +1.00 m, +1.50 m, +2.00 m, and +3.00 m SLR scenarios.
