Android平台GB28181设备接入端如何实时更新经纬度实现国标平台侧电子地图位置标注

技术背景我们在做GB28181设备接入端的时候，其中有个功能，不难但非常重要：那就是GB28181实时位置的订阅（mobileposition subscribe）和上报(notify)。特别是执法记录仪、智能安全帽、车载终端等场景下，现场人员的实时位置是国标平台侧非常关注的。国标平台侧通过周期性的...

Android GB28181接入端实时位置订阅和上报之-如何获取当前经纬度

我们在做Android平台GB28181的时候，其中实时位置(MobilePosition)订阅和上报这块，涉及到实时经纬度的获取，特别是执法记录、车载系统的那个等场景，几乎就是标配。今天主要是分享一段实时获取位置的代码：/* * CameraPublishActivity.java * Camer...

安卓（JAVA）已知两点经纬度，求出一条线上定距（比如隔20米或30一个点）的经纬度。

首先思考，已知两个经纬度，需要求出用户输入的定距来确定每一个点的经纬度，应该先确定从两个点的哪一个开始计算，这个自己定。然后需要根据两个点的经纬度来算出线的角度（相对于正北方向），最后进行计算。既然已经有了思路，那么就一步一步来。首先算出线的角度。我写了一个方法，可以直接...

安卓（JAVA）已知两点经纬度，求出一条线上几等分的点的经纬度。

话不多说，直接上代码。/** * 计算两点之间等距的经纬度 */ private List<LatLng> getDengLatLng(int number) { double aaa, bbb, ccc = 0, ddd = 0; List<LatLng> latLngs ...

安卓基于百度地图计算两个经纬度点的直线距离并只保留两位小数

需要计算地图上两个点的直线距离，查了下百度的官方API都是计算路程距离，于是乎自己写一个，根据地球的半径等来计算两个经纬度点的直线距离，好了，废话不多说，直接上代码。public Double Distance(double lat1, double lng1,double lat2, double...

Android笔记：高德地图-点击获得目的经纬度，根据经纬度获取地址（逆地理编码）

1.需要资源：高德地图搜索SDK以及相关SDk下载地址2.根据经纬度得到具体地址：1.这里需要用到地图搜索SDK；2.通过逆地理编码来实现。3.示例代码：首先要实现GeocodeSearch.OnGeocodeSearchListener接口 /** * * @author 程龙 */ public...

Android原生方式获取经纬度

Android原生方式获取经纬度两种定位方式：GPS定位、WiFi定位优劣：如果项目定位要求较高还是建议使用三方地图库 GPS定位相比Wifi定位更精准且可在无网络情况下使用，但在室内基本暴毙无法使用WiFi定位没有室内外限制也不需要开启GPS但需要联网,另外测试发现WiF...

Android 常用的地球经纬度转换公里（km）计算工具类

地球赤道上环绕地球一周走一圈共40075.04公里,而@一圈分成360°,而每1°(度)有60,每一度一秒在赤道上的长度计算如下：　　40075.04km/360°=111.31955km 　　 111.31955km/60=1.8553258km=1855.3m 任意两点距离计算公式见代码： p...

xamarin android使用gps定位获取经纬度

看了文章你会得出以下几个结论 1.android定位主要有四种方式GPS，Network（wifi定位、基站定位）,AGPS定位 2.绝大部分android国产手机使用network进行定位是没有作用的,肯定是无法获取获取位置信息（当然也肯定是有办法解决这种问题的） 3.android 的GPS定位...
