关于高德地图及其APP获取地图数据的研究

news 2025/8/25 0:31:10

        刚过完春节没几天，有个客户提出要获取高德地图的数据。



        我看了下，回复说：这不是很简单嘛，高德有公开的开放平台，有足够的API支持用户获取数据，开发自己基于高德数据库的应用。

        客户回复说：他的要求并不是简单的要求获取地图数据，以及某个POI（高德名词：信息点 -> Point Of Interest）的详细信息，客户要求基于高德地图的充电地图功能获取汽车充电站即时的充电枪信息，包括充电站位置、充电枪功率、目前是否在用等信息。

        嗯，研究一下吧！

一、高德API已经提供了足够多的功能，包括关键词搜索、POI地点搜索，而且这些功能高德已经更新迭代，同时放在开放平台上，支持用户调用。

比如搜索：北京/东城区/医院的信息，高德API会给出非常详尽的信息。

（信息已经经过我的代码解析，响应的json信息非常地全面）

再比如搜索：第一条信息，北京协和医院东单院区的详细信息：

}

可见信息也是非常详尽的。

二、关于客户的需求。

因为客户要求获取高德地图上更多的详尽信息。我发现这部分数据，并没有在开放平台公开的API中体现。而想要获取这部分数据，就有些难度了。

好消息是目前已经有了一定的进展。
