这个程序源码实现了mapx的绝大部分功能，非常经典！！并且我增加了一个重要功能，网上有许多人提出了这个功能，但是没有很好的解决。修改后，可以实现图层的动态移动，在创建折线时，当鼠标位于窗口边缘时，图幅自动平移，就像mapinfo一模一样的效果，并非简单的移动视图中心。当然你可以根据需要将功能扩充到在画直线、画多义线、画多边形的时候实现动态移动。具体功能与说明请下载后参阅ReadMeFirst。-the process to achieve the source of most of the functionality MapX, very classic! ! And I added an important function, the Internet has made many of the features, but not a very good solution. After revisions, the layer can be achieved for the dynamic movement, in the creation of dogleg, when the mouse is located at the edge of the window, maps automatic translation, like MapInfo exactly the same effect, is not a simple mobile View Center. Of course, you may need to expand the functions of the painting straight line paintings, the paintings polygon Dynamic Mobile. The specific function and description of downloading information ReadMeFirst.

用于对空间数据的投影变换。共实现了Albers、Lambert、高斯-克吕格、UTM和Mercator五种投影的正反变换。有需要函数使用说明的可通过EMail向作者索取。-right spatial data for the projection transformation. The total amount of Albers, Lambert, Gaussian- Krger, UTM and five Mercator projection transform the pros. The need to function for use by the author to obtain that extension.

应用背景在物力大地测量学中，重力异常的计算，需要测量计算点的重力值和计算测量点的正常重力。计算正常重力时，需要已知计算点大地坐标，即经度、纬度和大地高，如果采用GPS采集数据，那么获得的大地坐标的参考椭球是WGS84。关键技术此程序，采用WGS84参考椭球参数，因此输入数据为WGS84大地坐标，顺序为，纬度、经度、大地高。输入文件为，Input.dat。输出文件为，output.txt。计算结果为，椭球面以上高程为h处的正常重力。如果将大地高设为0，那么计算结果为此点处参考椭球面上的正常重力。

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.
