系统下,地球坐标转换的源代码,在WGS-84坐标和北京54坐标之间的一套转换参数,可以全国通用的，在每个地方会不一样，因为它们是两个不同的椭球基准。 // WGS2GK.CPP : C++ version of Ottmar Labonde s WGSDHDN3.PAS with CPU time measurement // compile with MS Visual C++ version 6.0 or do the necessary modifications for your compiler // // Conversion of -system, the Earth coordinates conversion source code, the WGS-84 coordinates and coordinate between Beijing 54 set conversion parameters can be nationwide, in every place to be different, because they are two different ellipsoid benchmarks.// WGS2GK.CPP : C version of Silverstone Labonde s WGSDHDN3.PAS with CPU time measurement// compile with MS Visual C version 6.0 or do the necessary modifications for your compiler//// Conversion of

The traffic light is timed and lets cars pass during a specific time period. There is a pedestrial crossing button that lets pedestrians cross. The lights are connected to Port 1. You can see this in action using dScope.
