Historically, Texans have turned to the Texas General Land Office for maps and other tools used to display and organize information about the state’s rich natural resources.
Besides historical maps, research, and data, the Land Office 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. This page contains a collection of dynamic, interactive mapping viewers, as well as downloadable GIS layers, that give Texans access to the vast collection of spatial data available at the agency.
