Our distances are not driving distances, but are calculated as a 'straight-line' distance. A straight line distance ignores obstructions like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- Long Island) to Point B.Our distance measurements begin at a specific point in Long Island. The point we use is located at these GPS coordinates - Latitude: 54.9169, Longitude: -132.6792 In this case, the coordinates for Long Island have been provided by the Geographic Names Information System (GNIS).
