垂直坐标系

本页对垂直坐标系（Vertical Coordinate System，VERT_CS）的基础参数的进行介绍，并统计了 252 个垂直坐标系的官方 ID（EPSG），坐标系名称，基准面，单位和垂直轴等参数。

#简介

　垂直坐标系可以定义高度或深度值的原点（轴）。与水平坐标系类似，除非要显示数据集或者要将数据集与使用不同垂直坐标系的其他数据合并，否则不需要使用垂直坐标系中的大多数信息。

　垂直坐标系主要由基准面、长度单位和轴组成。

#单位

　下表列举了本页垂直坐标系中涉及到的 4 个单位名称和每单位长度（类似于分辨率），以供与主要坐标参数中相关内容进行对应。

单位	中文对照	每单位长度（m）
metre	米	1
foot	英尺	0.3048
US survey foot	美国测量英尺	0.304800609601219
British foot (1936)	英国英尺（1936）	0.3048007491

#轴

　基于高度的垂直坐标系显示一个 Z 值。Z 值的正负取决于轴的方向。下表列举了本页垂直坐标系出现的 3 种轴相关参数，以供与主要坐标参数中相关内容进行对应。

轴名称	轴名称中文对照	轴方向	轴方向中文对照
Gravity-related height	重力相关高度	UP	向上
Depth	深度	DOWN	向下
Local depth	局部深度	DOWN	向下

#主要坐标参数

基准面

是指用来准确定义三维地球形状的一组参数和控制点。当一个旋转椭球体的形状与地球相近时，基准面用于定义旋转椭球体相对于地心的位置。基准面给出了测量地球表面上位置的参考框架。它定义了经线和纬线的原点及方向。
