三角高程网是高程控制网(vertical control,为测定地面点高程而建立的控制网)的一种,由三角高程测量方法传算高程的大地网。网中用水准测量或水准联测方法测定一些点的高程,作为已知高程点。
由离散高程点建立的三角网d TM,能够在多方面应用。如生成等高线、建立地面模型、计算土方量等。
Triangle network DTM building with concrete height points can be used for various aspects, e. g. generating contours, building surface model and calculating earthwork, etc.
从数据的采集,到三角网的构建,以及拓扑结构的形成,最后得到网格单元,准确的把煤炭地质高程显现出来。
From the data collection, to the triangle network topology construction, and the formation of grid unit, finally obtained the coal geology, accurate elevation revealed.
