摘要
以船舶航行的GPS定位为应用背景,介绍定位目标的空间位置坐标表示法,阐述在不同国家或地区将WGS-84大地坐标系转换成各地适用坐标系的方法,分析把三维坐标通过投影转换成二维平面直角坐标的过程,比较各种方法的不同适用性。
This paper takes GPS positioning for ship sailing as its application background, introduces several methods to describe special space using coordinate, expatiates methods to transform the WGS-84 coordinate system into proper coordinate system in different areas or countries,analyses process to transform three-dimensional coordinate into planar coordinate, compares the different applicability between these methods.
