默认值是北京中心的经纬度.<br><br>
google map <br><br>
1级zoom的图片是这张<br>
<a href="http://kh.google.com/kh?v=3&t=t">http://kh.google.com/kh?v=3&t=t</a> <br><br>
2级zoom时以0,0为中心.用0经度和0纬度(赤道)划分成4个均等区域,每个区域命名如下:<br>
q | r<br>
--|--<br>
t | s<br>
<br>
<a href="http://kh.google.com/kh?v=3&t=tq">http://kh.google.com/kh?v=3&t=tq</a><br>

3级以此类推......
