Systems and methods for route mapping

A method comprising:

• acquiring position information of a vehicle system moving along a track;
• calculating curvatures of the track, based on the position information, to form a curvature waveform, the curvature waveform representative of magnitudes of the curvatures of the track at different locations along the track;
• identifying one or more of the curvatures of the track as a circular curve in the track based on changes in the magnitudes of the curvatures that are within a designated threshold of a peak curvature magnitude in the curvature waveform;
• calculating a size of the one or more circular curves based on the magnitudes of the curvatures that are within the designated threshold of the peak curvature magnitude in the curvature waveform;
• and
• generating a route map based on the size of the one or more circular curves.
