#1314 closed enhancement (duplicate)

Improve robustness of linear referencing functions

Description

Using a location in the range 0..1 was not a very good idea. It happens easily that getting the location of an existing vertex and using that location to interpolate a point doesn't yeld the original vertex. See #1311 for such a case.

Using a full distance would be more robust. Even more robust would be using a segment number + a distance from segment's startpoint.
