This data release provides flood depth GeoTIFFs based on sea-level rise for the coast of the most populated Mariana Islands of Guam and Saipan in the Common Wealth of Northern Mariana Islands (CNMI). Digital elevation models were used to extract sea-level rise 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 sea-level rise scenarios.
