Texas Maps and Resources
GIS Maps and Data (Texas General Land Office)
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.
Map Collection Search (Texas State Library and Archives Commission)
The Texas State Archives Map Collection contains original, photo reproduced, and compiled maps covering the period from the early seventeenth through the late twentieth centuries. For general information about the holdings and descriptive information available, read the map introduction. For specific information to assist searching, read map index and type descriptions, map subjects list, and guide to codes. For reproductions policy, read notes on map preservation, access, and copies. For information on other maps in our holdings, read Maps in other Records Groups and Collections.

TNRIS archives, maintains, and distributes the largest collection of current and historical spatial geographic data sets for the State of Texas. Our collection of maps, photos, documents and other spatial datasets have been acquired over time from multiple sources including state, federal, and local agencies with support and donations from private sources.

Conservation maps are grouped according to the topics Environmental (terrain, habitat types, soil types, etc.), Land Use (land use, agricultural and environmental threats), Natural Hazards (floods, hailstorms, earthquakes, tornadoes, etc.), and Weather (snow cover, annual precipitation, and annual temperature). Topographic maps are seamless across quadrangles.

Texas Digital Sanborn Maps (via TexShare ) (from off-campus, available only to ASU students, faculty, and staff using their ASU login credentials)
“Sanborn fire insurance maps are the most frequently consulted maps in both public and academic libraries. Sanborn maps are valuable historical tools for urban specialists, social historians, architects, geographers, genealogists, local historians, planners, environmentalists and anyone who wants to learn about the history, growth, and development of American cities, towns, and neighborhoods. They are large-scale plans containing data that can be used to estimate the potential risk for urban structures. This includes information such as the outline of each building, the size, shape and construction materials, heights, and function of structures, location of windows and doors. The maps also give street names, street and sidewalk widths, property boundaries, building use, and house and block numbers. Seven or eight different editions represent some areas.”
