I have a number of ferry routes that I would like to add to my Google Maps [GM]. I have used the Directions argument in the https statement to enable mapping of both terminals of the ferry route [see below]. This, however, results in displaying a route over the road network between the points, where what I'm trying to achieve is a a straight line across a body of water connecting the two terminals. [For clarity's sake, I omitted all of the Filemaker code that implements this action.]
Is this possible and, if so, how?
Thanks very much, Bill Cole
