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 drawn from Point A (ie- Shoreline Drive) to Point B.Our distance measurements begin at a specific point in Shoreline Drive. The point we use is located at these GPS coordinates - Latitude: 55.3750, Longitude: -131.7250 In this case, the coordinates for Shoreline Drive have been provided by the Geographic Names Information System (GNIS).
