Package Exports

turf-midpoint

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (turf-midpoint) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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
