MapKit是否提供高程数据？ [英] Does MapKit provide elevation data?

问题描述

我正在使用Apple的 MapKit a>，我需要获得从 A点升级到 B点的高程变化。我知道< a href =https://developer.apple.com/library/mac/documentation/CoreLocation/Reference/CLLocation_Class/index.html#//apple_ref/occ/instp/CLLocation/altitude =nofollow> CLLocation 有一个高度属性，但它只会给你一个基于你当前位置的高度，而我需要从一个位置到下一个位置获得一系列高度点位置。

与使用Google地图+ Google Elevation API的此网络应用类似：

解决方案

MapKit不会给你这个，但你可以使用免费的MapQuest API 。

I am working on the iOS app that uses Apple's MapKit and I need to obtain elevation change from Point A to Point B.

I do know that CLLocation has an altitude property but it will only give you an altitude based on your current location, whereas I need to get a range of altitude points from one location to the next location.

Similar to this web app that uses Google Maps + Google Elevation API:

解决方案

MapKit won't give you this, but you could use the free MapQuest API.
