Google Map V2 Android和iOS放置latlng小数位 [英] Google Map V2 Android and iOS place latlng decimal places

问题描述

有一个Android以及我正在开发的iOS应用程序。
这两个应用程序都使用谷歌的PlaceAutocomplete控制器来获取位置的经纬度。在iOS中，我们可以获得纬度长达6位小数位，有时候也是5位。在android中，我们得到6个以上的小数位。

 例如，考虑位置Pune 
 Android Latlng：18.520431 ，73.856744 
 iOS Latlng：18.52043,73.856744 
  

正如您所看到的，同样位置的纬度精度。

有没有办法避免这种情况，因为我的应用程序需要比较这些经纬度？

解决方案

你不应该依靠坐标的精确度来比较它们，因为它们可以改变，或者，平台。

相反，您可以设置容差来确定两个位置是否相同。例如：

  float YOUR_TOLERANCE = 1; // 1米
 if（location.distanceTo（otherLocation）< YOUR_TOLERANCE）{
 //两个位置都被认为是相同的
} 
  

There is an Android as well as iOS application that I am working on. Both the applications use google's PlaceAutocomplete controller to get a location's lat-long. In iOS we get lat-long upto 6 decimal places sometimes 5 also. Where as in android we get more than 6 decimal places. The precision of the same location coordinate for Android and iOS differs.

For example consider location Pune
             Android Latlng: 18.520431,73.856744
                 iOS Latlng: 18.52043,73.856744

So as you can see there is difference between the precision of latitudes of the same location.

Is there a way to avoid this as my application needs comparison of these lat-longs?

解决方案

You should not rely on the precision of the coordinates to compare them because they can change or, as you experiment, vary between platforms.

Instead, you can set a tolerance to determine if two locations are the same. For example:

float YOUR_TOLERANCE = 1; // 1 meter
if (location.distanceTo(otherLocation) < YOUR_TOLERANCE) {
    // Both locations are considered the same
}
