TNRIS was established by the 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 is defined as the following in Sec. 16.021 of the Texas Water Code:
Sec. 16.021. TEXAS NATURAL RESOURCES INFORMATION SYSTEM. (a) The executive administrator shall establish the Texas Natural Resources Information System (TNRIS) to serve Texas agencies and citizens as a centralized clearinghouse and referral center for:
- natural resource data;
- census data;
- data related to emergency management; and
- other socioeconomic data.
A reliable and unique state resource that provides high quality historic and current geospatial data products, education and training, while advancing the GIS Community through collaboration, expertise, cost-sharing initiatives and exceptional customer service.
TNRIS is a division of the Texas Water Development Board (TWDB).
The Director of TNRIS acts as the coordinator of the Texas Geographic Names Committee, the body charged with standardizing geographic names for the state of Texas.
