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
以上!
