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).

功能：多线程、E
功能：多线程、E-mail转发、自动隐藏，huffman、JPEG压缩，全屏、指定区域或最前窗口抓图，窗口或全屏控制方式，彩色或黑白显示，修改注册表、取密码、记录键盘信息等等。
缺点：控制端在WIN98下运行，每抓一幅图会吃掉几十K内存，不知道为什么，在WIN2000下运行没有发现这种情况，知道原因请通知我。E-mail:KelvinSpace@21cn.com
Regedit:HKEY_CURRENT_CONFIG/CtrlSrvr设置E-MAIL地址等，电邮密码写在程序中（TVB）
服务端密码：TVB123(注意大小写)
文件：pe2.part01.rar至pe2.part05rar共5个文件
-Features: multi-threaded, E-mail forwarding, auto-hide, huffman, JPEG compression, full screen, specify the area or the front window, drawings, window or full-screen control mode, color or black and white display, modify the registry, get your password, record keyboard information and so on. Drawback: controlling end of the run WIN98, each grasping a plan would eat up tens of K of memory, do not know why, in the running under WIN2000 did not find such a situation, know the reason please let me know.
