包路径：org.geotools.referencing.CRS
类名称：CRS
方法名：getHorizontalCRS

CRS.getHorizontalCRS介绍

[英]Returns the first horizontal coordinate reference system found in the given CRS, or null if there is none. A horizontal CRS is usually a two-dimensional GeographicCRS or ProjectedCRS CRS.
[中]返回给定CRS中找到的第一个水平坐标系，如果没有，则返回null。水平CRS通常是二维地理CRS或投影CRS。
