Description
Takes a line, a start Point, and a stop point and returns a subsection of the line in-between those points. The start & stop points don't need to fall exactly on the line.
This can be useful for extracting only the part of a route between waypoints.
Parameters
| Name | Type | Description |
|---|---|---|
| startPt | Coord | starting point |
| stopPt | Coord | stopping point |
| line | Feature<LineString> | LineString | line to slice |
Returns
Feature<LineString> sliced line
Examples
var line = turf.lineString([
[-77.031669, 38.878605],
[-77.029609, 38.881946],
[-77.020339, 38.884084],

[-77.021884, 38.889563],
[-77.019824, 38.892368],
]);
var start = turf.point([-77.029609, 38.881946]);
var stop = turf.point([-77.021884, 38.889563]);
var sliced = turf.lineSlice(start, stop, line);
