No, there is nothing in the documentation. That's unsurprising, because it's considered that in creating a line you supplied its vertices. It doesn't envisage getting a line from GDirections and wanting to do something else with it, as well as putting it on a map. > If not, do you suggest that I fetch the points using > polyline.getVertex() and then re-encode the points ready for passing > to the elevation API? I wouldn't suggest that. I'd suggest ditching GDirections (which doesn't allow you to do what you want to do) and substituting a call to the web service: http://code.google.com/apis/maps/documentation/directions/ That does mean that you would need to do all the work GDirections does in displaying the line and results table, etc, but it gives you the line in a reliable manner. Displaying the table is covered by Mike's tutorial at http://econym.org.uk/gmap/steps.htm although that does get its data from GDirections. But it probably wouldn't be difficult to adapt. -- You received this message because you are subscribed to the Google Groups "Google Maps API" group.
