GIS: Useful Links

We strive to work in a collaborative effort with other state agencies in and outside of TDEC.  Certain projects could not have been completed with the assistance of The GIS Services Division in the Office of Information Resources, Tennessee Wildlife Resource Agency’s Office of GIS, and Tennessee’s Division of Forestry.

A great source of Tennessee GIS data is the Tennessee Spatial Data Server.  Developed by the Tennessee Federal GIS Users Group and the supported by the Tennessee Geographic Information Council (TNGIC), this server distributes spatial data layers that are shared among Federal, State, and local GIS facilities in Tennessee.

A useful tool that we use quite a bit is DNR Garmin.  Produced and maintained by Minnesota’s Department of Natural Resources, this extension was built to provide users the ability to directly transfer data between Garmin GPS handheld receivers and various GIS software packages. Using this program a user can use point features (graphics or shapefile) and upload them to the GPS as Waypoints. Line and Polygon Graphics or shapes can be uploaded to the GPS as Track Logs or Routes. Conversely, Waypoints, Track Logs, and Routes collected using the GPS can be transferred directly to ArcView/ArcMap/Google Earth/Landview and saved as Graphics or Shapefiles.
