<1> | Our distances are not driving distances, but are calculated as a 'straight-line' (or point-to-point) distance. A straight line distance ignores obstructions like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- Willow Grove) to Point B.Our distance measurements begin at a specific point in Willow Grove. The point we use is located at these GPS coordinates - Latitude: 38.9334, Longitude: -81.8360 In this case, the coordinates for Willow Grove have been provided by the Geographic Names Information System (GNIS). |
