Texas Geographic Information Office

The Texas Geographic Information Office (TxGIO) is a division of the Texas Water Development Board that maintains the geographic information system (GIS) of the government of Texas. It serves as the principal archive for natural resources data in the state. The Texas Geographic Information Officer servers as the director of TxGIO and also coordinates the Texas Geographic Names Committee.

History
TxGIO was established by the Texas Legislature in 1968 as the Texas Water-Oriented Data Bank. In 1972, after four years of growth and diversification, it was renamed the Texas Natural Resources Information System (TNRIS). In 2023, the 88th Texas Legislature officially renamed TNRIS to the Texas Geographic Information Office.

Services
The mission of TxGIO is to provide a "centralized information system incorporating all Texas natural resource data, socioeconomic data related to natural resources, and indexes related to that data that are collected by state agencies or other entities." (Texas Water Code, 16.021).

TxGIO provides a central access point for Texas Natural Resources data, census data, digital and paper maps, and information about datasets collected by state agencies and other organizations. It publishes historical and current aerial photography and printed topographic maps from the United States Geological Survey as part of its public domain data warehouse. It also provides GIS educational services.

The TxGIO offices are located in the Stephen F. Austin Building, 1700 North Congress Avenue, in Austin, Texas.
