Our distances are not driving distances, but are calculated as a 'straight-line' distance. A straight line distance ignores things like rivers, canyons, lakes, et cetera - it's truly a line from Point A (ie- East Greenwich) to Point B.Our distance measurements begin at a specific point in East Greenwich. The point we use is located at these GPS coordinates - Latitude: 41.6334, Longitude: -71.4992 In this case, the coordinates for East Greenwich have been provided by the Geographic Names Information System (GNIS).
