@turf/line-slice-along

lineSliceAlong

Takes a line, a specified distance along the line to a start Point, and a specified distance along the line to a stop point and returns a subsection of the line in-between those points.

This can be useful for extracting only the part of a route between two distances.

Parameters

• line (Feature<LineString> | LineString) input line

• startDist number distance along the line to starting point

• stopDist number distance along the line to ending point

• options Object Optional parameters (optional, default {})

  • options.units string can be degrees, radians, miles, or kilometers (optional, default 'kilometers')

Examples

var line = turf.lineString([[7, 45], [9, 45], [14, 40], [14, 41]]);
var start = 12.5;
var stop = 25;
var sliced = turf.lineSliceAlong(line, start, stop, {units: 'miles'});

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

Returns Feature<LineString> sliced line
