Our distances are not driving distances, but are calculated as a 'point-to-point' distance. A straight line distance ignores obstructions like rivers, canyons, lakes, et cetera - it's truly a line drawn from Point A (ie- Baltimore) to Point B.Our distance measurements begin at a specific point in Baltimore. The point we use is located at these GPS coordinates - Latitude: 34.4366, Longitude: -78.4403 In this case, the coordinates for Baltimore have been provided by the Geographic Names Information System (GNIS).
