The system performance variations for the railway track surveying due to the different choices of coordinateprojection and system model description are analyzed .
针对轨道动态检测系统，分析了选择不同的坐标投影及系统模型描述对系统性能的影响。

The advantage of coordinateprojection method is to analysis the stability of not only block but also structural plane and judge whether structural plane or block first collapses.
坐标投影作图法的优势在于不但能对多块体进行稳定分析，而且对单一的结构面也可对其进行稳定分析。

You then project (or transform) the coordinate from WGS84 latitude and longitude (EPSG: 4326) to the map's current projection (Spherical Mercator) and zoom to it.
