是程序计算从选定的点的地形图的可见性。我..
这个程序可以计算给定点处的小区信号范围覆盖。-is program computes a map of visibility from a selected point on a topography. It has been written to help the search for radio relay best location. Because it considers only direct line of sight, it gives a good estimation for possible radio link for short distances only (less than 10 km), neglecting curvature of the Earth, Fresnel zone and atmospheric refraction on radio waves propagation. The program computes the relative elevation angle of the mask for each point (the angle is null or negative if the point is visible).
The function needs a digital elevation model Z and associated (X,Y) vectors or matrices of coordinates (same unit as Z), position of the point (X0,Y0), the antenna height H0 (for instance 4 m), and the hypothetic antenna height Ha on each topography points (for instance 3 m). When no output argument is given, the function plots a map of the results (color map of mask angles, and blank for visible points, see example screenshot).

本软件由ZHG用TC2.0开发，可用来进行简单画图、查看由本软件制作的图形文件以及使用配套函数show_bmp在C语言程序中直接使用已画好的图形。具体操作如下：
1.主界面上方为菜单栏，左边为工具栏。要使用请单击“新建”或“打开”按钮，退出可单击右上角椭圆。
2.进入后，可单击工具栏选择画笔、规则图形及颜色。左击图形库，画实线图，右击可画虚线图。在编辑区中，用左键拖动鼠标为画笔画图，右键拖动可画规则图形。（建议下载到D盘）
