A feature dataset of lands owned and/or managed by TWRA was compiled from a variety of sources at various map scales, projections, and dates. This feature dataset has undergone continuous revision, update, and review.

This feature class contains points representing the locations of Tennessee State Parks. These points are calculated as the centroid of each Tennessee State Park boundary. The locations represented within do not constitute a survey product and are not legally binding. Limited attributes include park name. The data are updated weekly on Wednesdays to reflect the most up-to-date boundary information. For printable and downloadable maps of our Tennessee State Parks, please visit TNStateParks.com.

Agency: TN Department of Transportation. The imagery is flown on a regional basis, and updated on a county-by-county basis as new imagery is made available. For more information visit imagery.tn.gov

The Road Segment table describes the administration and ownership of the segment of road. It contains tabular polyline data showing the log miles/measures, road name, functional class, government control, and U.S. Routes. Road names are derived from visual surveys by field crew or official GIS maps. Functional class is set by the Federal Highway Administration (FHWA). All other categories are determined by state and local agencies. This dataset is updated weekly.
