The State of Texas has the largest land area of any in the contiguous United States, and its sprawling landscapes show rich geographic diversity. The Lone Star State has cactus flats in the high plains of its far western panhandle, rolling hills in its western Trans-Pecos region, farms and ranchlands stretching across central Texas, thick forests and swamplands spread through the east, and 3,359 miles of Gulf of Mexico coastline. The consistent, reliable, and historically unique Landsat data archive provides an important tool for Texans to track landscape changes and enhance their economy and environment. And as a free and open data source, Landsat makes a particularly cost-effective tool.
