兰勃特投影在铁路工程独立坐标系设计中的应用

Application of Lambert Projection in Independent Coordinate System Design for Railway Engineering

文章探讨了铁路工程独立坐标系选择设计的问题,以委内瑞拉北部平原铁路为例,介绍了兰勃特投影在铁路工程测量平面坐标系设计中的应用。为铁路工程测量选取既能满足投影长度变形要求,又尽可能减少投影分带数量的工程独立坐标系提供了一种新的思路和解决方法。

Taking Venezuela northern plain railway for example,this paper probes into the problem of design selection of independent coordinate system for railway engineering and presents the application of Lambert projection on measuring plane coordinate system design,so as to offer a new settlement for selecting an engineering independent coordinate system that may satisfy the deformation of projection length and reduce projection zoning number as far as possible for railway engineering survey.
