Iterate over each geometry in any GeoJSON object, similar to Array.forEach() 接收任意类型的 GeoJSON，遍历它的每个 Geometry。功能类似 Array.forEach()

参数

参数	类型	描述
geojson	FeatureCollection|Feature|Geometry	任意 GeoJSON 对象
callback	Function	回调，参数依次是 currentGeometry、featureIndex、featureProperties、featureBBox、featureId

返回

undefined - undefined

示例

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

turf.geomEach(features, function (currentGeometry, featureIndex, featureProperties, featureBBox, featureId) {
  //=currentGeometry
  //=featureIndex
  //=featureProperties
  //=featureBBox
  //=featureId
});
