Adding a waypoint at a specifc distance along route

[skube]

Hi, I'm wondering if anyone might be able to help. I would like to create a directions map that obviously has an origin and destination plotted. However, I would like to drop a marker at some distance along the route polyline (not radially from the origin). Does anyone know if this is even possible?

thanks!

Sure. You can get the route, then compute the coordinates of a point
at a certain distance along it and put a marker there.

One example:
http://www.geocodezip.com/v3_polyline_example_kmmarkers_0.html
(markers every 2 km)

Another example:
http://www.geocodezip.com/v3_GoogleEx_directions-waypoints_kmmarkersC.html
puts markers at:

createMarker(polyline.GetPointAtDistance(9500),"9.5km","9.5km");

createMarker(polyline.GetPointAtDistance(64800),"64.8km","64.8km");
(uses a ported version of Mike Williams (v2) epoly library, there are
probably better ways to do it now)
