Our distances are not driving distances, but are calculated as a 'straight-line' distance starting from Aspel. A straight line distance ignores obstructions like rivers, canyons, lakes, et cetera - it's truly a line drawn from Point A (ie- Aspel) to Point B.
Our distance measurements begin at a specific point in Aspel. The point that we are using is located at these GPS coordinates - Latitude: 34.6209, Longitude: -86.1655 [Map]. In this case, the coordinates for Aspel have been provided by the Geographic Names Information System (GNIS).
