Our distances are not driving distances, but are calculated as a 'point-to-point' distance beginning in Georgia. A straight line distance ignores obstructions like rivers, canyons, lakes, et cetera - it's truly a line drawn from Point A (ie- Georgia) to Point B.
Our distance measurements begin at a specific point in Georgia. The point that we are using is located at these GPS coordinates - Latitude: 34.4534, Longitude: -86.9281 [Map]. In this case, the coordinates for Georgia have been provided by the Geographic Names Information System (GNIS).
