Yes, this is default. The wiki has been updated. > […] > Second, (and this might be related to the first) it seems that either > I am missing some subtleties in the Google's Polyline Algorithm Format > or the coordinates which are returned by demo server are off by a > factor of ten. It is not off by 10 but rather more precise than the previous implementation. See the Wiki page for a link to a proper JavaScript implementation of the decoder. > Third, the "Server API" wiki page specifies that &checksum=$value > should be added to the URI when using coordinate hinting, where $value > is drawn from the last query's hint.checksum attribute.

If not what point does this value serve? It may change at the servers discretion. > Turned out longer than I expected, hope this is not too much to ask, > thanks in advance. --Dennis _______________________________________________ OSRM-talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/osrm-talk
