2019-03-28-百度地图接入及使用

背景

近期工作中涉及大量百度地图的使用,主要用于展示地图效果,少量交互。其中包含,中国地图边界绘制,自定义地图样式,自定义描点。

百度地图接入

1.注册百度账号
2.申请成为百度开发者
3.获取密钥(AK)
4.发送请求,使用服务

坐标类型分类

WGS84:为一种大地坐标系,也是目前广泛使用的GPS全球卫星定位系统使用的坐标系。
GCJ02:是由中国国家测绘局制订的地理信息系统的坐标系统。由WGS84坐标系经加密后的坐标系。
BD09:为百度坐标系,在GCJ02坐标系基础上再次加密。其中bd09ll表示百度经纬度坐标,bd09mc表示百度墨卡托米制坐标。
RouteMatrix API v2.0的输入参数支持以上三种坐标系,开发者无需进行任何坐标转换,只需通过输入参数”coord_type”指明所使用的坐标系即可。
