@turf/line-slice v7.2.0

@turf/line-slice

lineSlice

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

• startPt Coord starting point
• stopPt Coord stopping point
• line (Feature<LineString> | LineString) line to slice

Examples

var line = turf.lineString([
    [-77.031669, 38.878605],
    [-77.029609, 38.881946],
    [-77.020339, 38.884084],
    [-77.025661, 38.885821],
    [-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);

//addToMap
var addToMap = [start, stop, line]

Returns Feature<LineString> sliced line
