GE and Charts with elevation profile

[Antonio Manuel Acevedo]

Hi all!

I´m trying to create an elevation profile with two graphs:

 1. The flight of my plane.

 2. The ground profile of the flight.

I´m using an google areachart with two series to show that.

My problem is that i need some way to split my linestring of the terrain in 100 chunks (for example) to show the terrain with a good level of acurracy.

Why is the quickest way to create an elevation profile? 

Is there any feature i could use to get 'x' points within a linestring composed of 2 coordinates (beggining and ending)?

I´ve show the midpoint function but i don´t now if is the quickest way...

Regards ;)
