This dataset contains measurement of the center of roads entering into and exiting from Welcome Centers statewide. The road centerlines were obtained using a vehicle mounted Trimble ProXRS or GeoExplorer Series GPS receiver. Real-time Omnistar or Satellite Base Augmentation System (SBAS) were applied during the collection. Differential post-processing correction was also applied to enhance data accuracy when real-time Omnistar or SBAS was unavailable. There are 11 welcome centers throughout the state of Georgia. These are typically located at the boarder of adjacent states. |
