Something wrong with CrossTrackDistanceTo ? It assumes a line instead of line segment ?

When trying to calculate the distance to the start stop segment this function's implementation seems to ignore the line segment concept.

In other words, this math assumes the start to stop is a line throughout the universe or in this case throughout the sphere, basically and endless line which wraps itself around the earth infinityly...

I need a version of this function which will respect the line segment concept and return a larger distance if the point is beyond the start and stop points...

(I ported the C++ code version to Delphi pretty well, but so far my visualizations show this function seems to compute an infinite line across the sphere... )

Maybe I or you can combine the AtTrackDistance and the CrossTrackDistance to make a function that behaves like a line segment... hmmm...

[SkybuckFlying]

Or maybe that is what isWithinExtent is for ? hmmm...

Another idea could be to use:

nearestPointOnSegment to compute the point which is closest on that segment...

then compute DistanceTo(closestPointOnSegment)

I think this should work for what I want.

Closing this for now :)
