4个直辖市是手动添加上去的

2 坐标系

坐标系相关的知识；上面获取到的是百度坐标系 需要转换的如下方法：   网盘地址：http://pan.baidu.com/s/1huRBw  感兴趣的可以点击链接下载！

国家规定，军队，国家机关的涉密数据。。。。。。不能使用WGS84坐标系，大家开发项目请注意。

比较专业的坐标相互之间的转换如下：

3 获取坐标值的方法

http://api.map.baidu.com/geocoder/v2/?ak=你在百度申请的KEY&output=json&address=城市名称&city=XX省   【百度的获取地址】

上一篇提到了怎么获取全国的省市县镇乡村。。。。。想了解的请点击    【http://www.cnblogs.com/chinhi/p/jsoupgetdata.html】  不好意思。。。连接给错了  不过也可以点击

[亮一下你的眼睛]

有了数据如下：

然后数据库查询一下：【select name from tab where name is not null and name !=''】

读取到list集合  然后for循环执行百度坐标即可。。。。。。。。。。。。。。。。。。。。。。。。。

然后就去到了最上面的地理坐标数据，你就可以猥琐欲为了

哈哈 ！

另外附上北斗坐标系的转换。。。。。。。。。。。。。。。。。http://pan.baidu.com/s/1dDdkW7J

最后看下我的平台。    www.10086bank.com

要我能提供的源码，请在里面发邮箱获取。。。。。。

以上！
