自己编的，在MO2.2环境下，设计GIS应用程序（用VB），实现对地图数据的浏览(例Mexico），能分别完成图像的放大、缩小、移动和还原。

vc＋＋ 平台实现的，采用对话框形式，利用mapx工具编程，实现 放大，缩小，还原，测量距离，查看图层信息等功能，适合初学者-vc platform to achieve, using the dialog box, using MapX tool for programming, to achieve amplification, reduced, reduction, measuring the distance to see features such as layers of i

对于光纤信号,经耦合器之后,在labview中实现对信号的还原.-For optical signals, the coupler after the implementation of the signal in labview reduction.

可以打开shape点、线、面文件，实现放大、缩小、漫游、还原功能。可以对点、线、面进行缓冲区分析-read shape file, zoomout, zoomin, move, reset. Buffer analysis
