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. These tools 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.
The Land Office website contains a collection of dynamic interactive mapping websites that give Texans access to the vast collection of spatial data available at the agency.
