Geographic Information Systems
Maps & Data

Historically, Texans have turned to the Texas General Land Office for maps and other tools used to organize information about the natural resources this state has to offer. Besides historical maps, research, and data, the land office today uses Geographic Information Systems (GIS), Global Positioning Systems (GPS), and Computer-aided Design (CAD) systems to compile, analyze, and distribute the most accurate information possible about the location of natural and human-made resources. In the areas of mineral leasing, Oil Spill Response, Coastal Resource Management, and land surveying needs, GIS, GPS, and CAD systems support the business functions of the General Land Office and serve as critical tools in the study and protection of our state's valued resources. Much of the data dealing with coastal resources is also being used in multi-organizational efforts such as the Texas Wetland Information Network (WetNet) and the Texas Natural Resources Inventory (NRI).
