Functions

fun chunk(fixes: List<Fix>, maxPointsPerChunk: Int, overlapPoints: Int): List<TraceChunk>

Split fixes into request-sized windows, each sharing up to overlapPoints points with the previous window.

fun downsample(fixes: List<Fix>, targetIntervalSec: Double): List<Fix>

Thin fixes so consecutive kept points are at least targetIntervalSec apart, without moving or dropping the first or last fix.

Recombine one MatchedRoute per chunks entry into a single trip distance, counting the overlap between consecutive chunks exactly once.
