参数 类型 描述

callback Function a method that takes (previousValue, currentCoord, coordIndex)
initialValue (*) Value to use as the first argument to the first call of the callback.
excludeWrapCoord boolean whether or not to include the final coordinate of LinearRings that wraps the ring in its iteration.


    • The value that results from the reduction.


var features = turf.featureCollection([
  turf.point([26, 37], {"foo": "bar"}),
  turf.point([36, 53], {"hello": "world"})

turf.coordReduce(features, function (previousValue, currentCoord, coordIndex, featureIndex, multiFeatureIndex, geometryIndex) {
  return currentCoord;
