谷歌地图和API显示不同的结果 [英] google map and api shows different results

问题描述

我很惊讶我是否做错了。当我找到谷歌地图上的两个位置之间的距离说maps.google.co.uk，当我查询他们的API我得到不同的结果。我是否缺少somethng？

原产地：英国伦敦骑士桥海德公园角落站
目的地：The Ritz英国伦敦
结果：1.2英里

而且当我使用api时： b
$ b

http://maps.googleapis.com/maps/api/directions/json?origin=Hyde%20Park%20Corner%20Station,%20Knightsbridge， ％20London，％20United％20Kingdom& destination = The％20Ritz％20London，％20United％20Kingdom& region = gb& sensor = false& alternatives = alternatives&true& units = imperial

结果：4.3英里或5.0英里等。

为什么会有这么多差异。我错过了什么。

解决方案

Google地图和路线服务（或地理编码）之间存在显着差异。 b $ b

Google地图最初是Google地方信息的实施，这就是问题所在。 directions-service使用地址解析来解析地址，而Google Maps使用PlacesService。

使用directionsRenderer绘制路线时，您会看到有不同的起点 - 和结束位置。

但是，当您首次请求PlacesService获取地点坐标并使用这些坐标请求directionsService时，您将得到一个结果附近的谷歌地图的结果（持续时间可能会有所不同，因为默认情况下directionsvices不会返回结果，取决于当前流量）

I am surprised whether i am doing any wrong or not. When i am finding the distance between two locations on google maps say maps.google.co.uk and when i query their API i get different result. Am i missing somethng?

Origin:Hyde Park Corner Station, Knightsbridge, London, United Kingdom Destination:The Ritz London, United Kingdom Result: 1.2 miles

And when i am using api:

http://maps.googleapis.com/maps/api/directions/json?origin=Hyde%20Park%20Corner%20Station,%20Knightsbridge,%20London,%20United%20Kingdom&destination=The%20Ritz%20London,%20United%20Kingdom&region=gb&sensor=false&alternatives=true&units=imperial

Result:4.3 miles or 5.0 miles etc.

Why is there so much of difference . Am i missing something.

解决方案

There are significant differences between Google Maps and a service like directions(or geocoding)

Google Maps at first is an implementation of Google Places, and that's the issue here. The directions-service uses geocoding to resolve the addresses, while Google Maps uses the PlacesService.

When you draw the route using the directionsRenderer, you will see that there are different start-and end-locations.

But when you first request the PlacesService to get the coordinates of the places, and use these coordinates to request the directionsService, you will get a result near by the result of Google Maps(the duration may differ, because the directionsService by default will not return results depending on the current traffic)
