实现空间分析、属性查询、框架设计等

不用注册就可以完成各种常用的地图投影：UTM、Albers、高斯、兰勃特、墨卡托等几十种投影，以及它们之间的相互转换；数据处理方式多样：单点、多点、文件方式；椭球可选；注册后功能更多。 -Registration can be completed without a variety of commonly used map projection: UTM, Albers, Gauss, Lambert, Mercator, etc. dozens of projection, and their mutual conversion data processing and diverse ways: a single point, multi-point , paper ellipsoid optional register more after the function.

包含了大量的mapx资源，是不可多得的好东西，快来看吧。-including many incrediable mapx resource,come on to look!

一种很实用的扫描算法，主要功能是通过两次扫描找出正方形区域内集聚中心。-a very practical scanning algorithm, the main function is to scan through to find two square region Gathering centers.

一个使用mapx的gis例子！-a use MapX the gis example!

有关mapinfo的源程序，主要是用于GIS的二次开发。-the source, GIS is used mainly in the secondary development.

本程序是将不同波段的遥感图象进行处理，通过主成分分析，最后合成一幅遥感图象。-the procedure is different band of remote sensing image processing, through principal component analysis, the final synthesis of a remote sensing image.
