根据椭球大地坐标求正常重力

GIS数据的读取源码！尤其包括了对DWG文件的读取的代码！-GIS data source to read! Including, in particular, on the DWG file to read the code!

鹰眼实现(vb+mapx50)-breath-5, a program file to show that I will be my last set of five procedures is described.

基于MO保存GIS可视化工程文件(不够20个字)。已经说得很清楚了，为什么还要罗嗦呢?站长应该修改程序，免得让人罗嗦？-MO-based GIS visualization Save project file (not 20 words). Have explained very clearly, why this wordy? Regulators should revise procedures to prevent people wordy?

本程序是用vc编写的有关gis开发的基本框架 利用此框架可以进行更深层次的开发-this procedure is used in the preparation of vc gis the basic framework for the development of this framework can be used for the development of a deeper level

This application not only demonstrates the basics of using the Microsoft Foundation classes but is also a starting point for writing your application.

vb通讯《GIS开发者》Visual Basic 是Mcrosoft公司推出的强有力的系列开发软件之一，而且以其实用、方便、快捷、开发周期短、广泛而强大的功能越来越被广大编程人员所亲赖，广为流传，似乎有些专业的编程人员放弃了Visaul C++ 而改用了Visaul Basic之类的RAD编程工具，尽管Visaul C++在灵活性、代码紧凑、运行速度快及底层开发等方面Visaul Basic无法比拟的，但编写C++应用程序过长的调试和开发周期确实有点不适应当今的应用程序开发环境。-vb communications, "GIS" Visual Basic is Mcrosoft launched a series of powerful software development, but its practical, convenient, fast and short development cycle, extensive and powerful features are increasingly the majority of programmers are pro-Lai, the most widely circulated, it appears that some professional programmers abandoned FoxPro C and switch to the Basic FoxPro like RAD programming tools, despite the flexibility of C FoxPro, code compact, fast operation and development, and so on the bottom FoxPro Basic incomparable, but the C application debugging and long development cycle is really not suited to today the application development environment.
