Hi,

Goal is to draw a route by joining points so if two consecutive points are in a curve the line joining these two points follow that curve.

I tried to use polylines to draw route. However if two points - GPS taken - show in different positions of a curve the straight line joining these two points - arc - obviously do not follow the curve.

The problem is resolved calculating the route after waypoints. However would there be any way to hide the labels [1],[2], ... of the waypoints that show once a route is calculated ?

Alternatively would there be any way to draw a route using a freeform to the shape of the freeform follows the curve of the route?

Thanks,

Are you trying to get your 'route segments' (ie. the lines between the GPS points) to follow roads, or to followa smoothed line?

If the former, then loading the points into the route (as you've tried) is the best way as long as the points are close enough. It is perfectly possibly for you to take a different road route to what MapPoint thinks is optimum!
No, I don't think you can switch the waypoint numbers off.

If you go for a smoothed line, you will need to do some programming to implement a spline or bezier algorithm. This could then draw a nice smooth curve that goes through all of your points. This might look better, but will bear no resemblence to the underlying map - except for the locations of your GPS points. Ie. the algorithm is some clever maths and doesn't take any notice of road positions.

I could probably be hired to code this up. I've never implemented this on the Earth's surface, but the transformations aren't a big deal.
