Building a Stream Map of the Austin Region
by Juling Bao
The Texas Natural Resources Information System (TNRIS) is a huge data source available through the network. It offers a wide range of natural resource information in Texas including roads, streams, railroads, urban streets and etc. The data obtained from this system are often the fundamental data for both academic research and construction planning. So the testing of the correctness of these data becomes important

The latest version of The Texas Natural Resources Information System (TNRIS) is the source of most data and information. It contains two main sets of maps: TxDOT County Map Series and TxDOT District Map Series. It covers all 254 counties in Texas and all features including streams, roads, railroads, streets and etc.
