a client would decode the field by substracting delta lon2 from lon1 as well as substracting delta lat2 from lat1 and dividing result with 1e5. This would result in a coordinate pair from which delta lat3 and delta lon3 could again be substracted and so on. First lat1 and lon1 should be just divided with 1e5.
