Android地图GPS异常 [英] Android Maps GPS outlier

问题描述

使用Android地图API我创建的多边形，因为我从每一个第三点收集位置数据。多边形跟踪我的位置相当好。

Using the Android maps api I'm creating polygons as I collect location data from every third point. The polygons track my position fairly well.

问题是：频繁的GPS返回绕过障碍物时没有关闭远程分特

Problem is: Frequently the GPS returns points that are not remotely close especially when working around obstacles.

我如何过滤我的位置数据离群？

How can I filter my location data for outliers?

推荐答案

是GPS有一个困难时期尤其是在障碍物。输电线，建筑物等简单过滤出来。

Yes GPS has a hard time with especially around obstacles. Powerlines, buildings, etc. Simply filter them out.

@Override
public void onLocationChanged(Location location) {
        if (!location.hasAccuracy()) {
            return;
        }
        if (location.getAccuracy() > 10) {
            //possibly tell user gps accuracy with transparent circle like the maps 
            //application does.
            return;
        }

//process location accurate to 10 meters here
}
