Hi all,

before I begin, let me tell that geometry is not exactly my strong
suite so please forgive my probably dumb question.

I have started to work with boost geometry which, I find very neat,
and assembled a line string.

Now I basically need a method that gives me a point to a length value.
Like when my linestring is 100 units long and I say give me the point
at 3 I want the exact position of the point (coordinates) as if I were
following the line for exactly 3 units.

I have an approach that would allow me to implement this myself by
following the segments (possibly after indexing them) but I have a
feeling that one of those many functions provided by the library
itself might do just that and I simply don't know it. If anyone knows
if such is the case, would be nice to give me a heads up.

Thanks,

Stephan
