turf-midpoint

turf-midpoint

midpoint

Takes two points and returns a point midway between them. The midpoint is calculated geodesically, meaning the curvature of the earth is taken into account.

Parameters

• from Feature<Point> first point
• to Feature<Point> second point

Examples

var pt1 = {
  "type": "Feature",
  "properties": {},
  "geometry": {
    "type": "Point",
    "coordinates": [144.834823, -37.771257]
  }
};
var pt2 = {
  "type": "Feature",
  "properties": {},
  "geometry": {
    "type": "Point",
    "coordinates": [145.14244, -37.830937]
  }
};

var midpointed = turf.midpoint(pt1, pt2);
midpointed.properties['marker-color'] = '#f00';


var result = {
  "type": "FeatureCollection",
  "features": [pt1, pt2, midpointed]
};

//=result

Returns Feature<Point> a point midway between pt1 and pt2
