The Tennessee Information for Public Safety (TIPS) product is a comprehensive dataset that contains various Geographic Information System GIS) data layers benefiting public safety agencies within state and local government. The core layer in this product is the digital, statewide street centerline database. In 2007, the Office for Information Resources, GIS Services section (OIR-GIS Services) completed the initial statewide GIS data production through the Tennessee Base Mapping Program (TNBMP). To learn more about the TNBMP, please visit the Base Mapping area of our website.
To sustain the long term use of these GIS data layers in a variety of State and local GIS applications, appropriate data maintenance roles and responsibilities must be established. Working with the Tennessee Emergency Communications Board (TECB), OIR-GIS Services is under contract to help facilitate the maintenance of the TIPS product. Working with local E9-1-1 districts, OIR-GIS Services will be consuming locally updated geometry and tabular information (street addresses, names, etc.) and integrating these local updates into a single, consolidated and standardized street centerline database. In turn, OIR-GIS Services will provide local E9-1-1 districts with the updated statewide centerline at no cost to the districts. The ability for local E9-1-1 districts to share and exchange data with OIR-GIS Services will allow the districts to effectively manage their operations and improve public safety.
The ability for OIR-GIS Services to effectively maintain this street centerline database and provide quality information to the E9-1-1 districts is dependent upon the willingness of each local E9-1-1 district to share their data with OIR-GIS Services. Moreover, data quality is based on the ability of OIR-GIS Services to develop and adhere to specific data maintenance standards. The following documents and links provide more information on the specific street centerline and addressing standards that OIR-GIS Services will use to maintain this statewide database, as well as a look at current production.
