bezierSpline

Takes a line and returns a curved version by applying a Bezier spline algorithm.

The bezier spline implementation is by Leszek Rybicki.

Parameters

  • line Feature<LineString> input LineString
  • options Object Optional parameters (optional, default {})
    • options.resolution number time in milliseconds between points (optional, default 10000)
    • options.sharpness number a measure of how curvy the path should be between splines (optional, default 0.85)

Examples

var line = turf.lineString([
  [-76.091308, 18.427501],
  [-76.695556, 18.729501],
  [-76.552734, 19.40443],
  [-74.61914, 19.134789],
  [-73.652343, 20.07657],
  [-73.157958, 20.210656]
]);

var curved = turf.bezierSpline(line);

//addToMap
var addToMap = [line, curved]
curved.properties = { stroke: '#0F0' };

Returns Feature<LineString> curved line
