最短路经算法示例（需要mo2.1和vb）

WIN XP下操作并口的最好控件，有中断、位等，代码DEMO很丰富。-WIN XP parallel port to operate under the best control, have interrupted, etc., code DEMO very rich.

这是我学习 MapObjects 时所编写的代码，具有一定的参考价值！-MapObjects study prepared by the code, with some reference value!

1、示例程序的目录下必须有Map(地图数据)目录，方可正常运行，否则无法打开地图。 2、重新编译Delphi源代码前，需配置相关的组件环境。-1, the sample program directory must Map (map data) directory before normal operation, otherwise it is impossible to open the map. 2, Delphi recompile the source code, configuration of component environment.

vc实现GIS地图图上绘制各种标号的功能。-vc GIS maps on the plan to draw various labeling functions.

VC++做的GIS源码very good,please give good say-VC++ Source GIS do very good, please give good say

应用背景随着地震勘探精度的提高,各向异性对于常规克希霍夫叠前深度偏移效果的影响已不容忽视.研究了利用P波非双曲旅行时求取各向异性参数的方法,当道集的排列长度远大于勘探目的层深度时,P波走时资料包含的信息可以用来确定VTI介质的各向异性参数关键技术利用VTI介质的CMP道集,研究了二步法提取η参数的方法,即先利用短排列地震数据求取均方根动校正速度,再利用长排列数据和水平速度扫描法得到水平速度,通过转换得到各向异性η参数；采用基于声学近似的VTI介质程函方程,通过各向异性射线追踪计算旅行时

一个计算面的平均高程的程序，可以求得任意形状的面的平均高程。-A calculation of the average surface elevation of the procedure, you can find any shape of the average surface elevation.

3维地理信息系统数据模型的设计，很好的例子帮你解决问题-3-dimensional GIS data model design, a good example to help you solve the problem

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.
