实现了图的数据结构，以及错切、旋转、拉伸移动等算法（TurboC2.0下运行，编译前修改库路径）。-achieved map data structure, and Shear, rotation, stretching movement algorithm (TurboC2.0 running, compile amending the library path).

读取raw数据格式图像，转换为bmp图像保存 实现批量读取转换，带测试图。运行run文件，需要修改当前测试图像路径。-Read the raw data format images converted to read bmp images are saved to achieve batch conversion, with a test pattern. Run the run file, you need to modify the current test image path.

C++版的A*（A-star,即A星）算法。对于栅格数据的最优路径搜索有不俗的表现。集成到你的程序也很容易。里面有两个例子可供参考。-C++ version of A* (A-star A star) algorithm. Have good performance for the optimal path to the raster data search. Is also very easy to integrate into your program. There are two exa

gps 轨迹重现 使用gps 数据可以在 地图上 重现你走过的gps 路径-GPS track to reproduce the use of GPS data can be reproduced on the map gps path you walk
