MapInfo MapX是一个用来做地图化工作的OCX控件，它可以很容易地在您的应用程序中加入强大的制图功能。它可以把您的数据用地图的形式显示出来，更易于理解。地图形式可以比简单的图表、图形提供更多的信息，而且描述地图比描述数据表更加简单迅速。本章主要对mapx的安装和在编程语言中的使用进行讲解。-MapInfo MapX is used as a map of the OCX controls, it can very easily in your application into a powerful mapping function. It could use your data in the form of maps, and easier to understand. Maps can be more than a simple form of charts, graphics provide more information, and the descriptions over the map data sheet describes more simply and rapidly. This chapter primarily MapX in the installation and programming language on the use.

首先得安装MapX控件，并在VC源文件中引用CMapX的头文件，能够实现放大，缩小，添加图层数据，进行图层的管理-first be installed MapX, and the VC source quoted CMapX the first document to achieve zoom in and out, add layers of data, the management layer

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
