The South Padre Island DEM covers the southern coastal region of the Gulf coast of Texas to the U.S. Mexico border. It also covers South Padre Island and the city of Brownsville. The DEM has a 1/3 arc-second (~10 meter) cell size, and is referenced to a vertical datum of NAVD 88. It was built in May 2012 for the National Tsunami Hazard Mitigation Program in support of the State of Texas' tsunami landslide modeling efforts.
