The 100 m false-colour image of 24 February 2016 shows us several barrier islands, near the Texan coast: from the bottom to the top: Padre island, Mustang Island, San Jose Island and Matagorda Island. Padre Island is the largest of the Texas barrier islands and is the world's longest barrier island. It is part of the U.S. state of Texas. The island is located along Texas' southern coast of the Gulf of Mexico and is noted for its white sandy beaches at the south end.
