【制作过程】
1）打开一个DOS窗口，转换目录到D:\g_capturer下，按照如下格式执行gcap_info.exe，生成相关地图的坐标信息文件（命名为hongshulin-18.txt）：
生成的坐标信息文件内容如下：
gcap_info verson 0.01, copyright 2007, all rights reserved.
g_capture parameters:
left: 113.990149
top: 22.528820
right: 113.998915
bottom: 22.522825
procision: 18
left-top map unit is:
http://kh.google.com/kh?v=3&t=trstrtttstqqqssrrts
right-bottom map unit is:
http://kh.google.com/kh?v=3&t=trstrtttstqqrttqtss
ozi map calibration info:
left-bottom point:
longitude: 113.990021 = 113 59.401245
latitude: 22.522706 = 22 31.362342
left-top point:
longitude: 113.990021 = 113 59.401245
latitude: 22.529048 = 22 31.742898
right-top point:
longitude: 113.999634 = 113 59.978027
latitude: 22.529048 = 22 31.742898
right-bottom point:
longitude: 113.999634 = 113 59.978027
latitude: 22.522706 = 22 31.362342
2)打开OziExplorer，选择file->Load and Calibrate Image Map，打开hongshulin-18.jpg，参考huongshulin-18.txt中的ozi map calibration info对该地图进行经纬度校准：
