本文整理了Java中org.geotools.referencing.CRS.parseWKT()方法的一些代码示例，展示了CRS.parseWKT()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。CRS.parseWKT()方法的具体详情如下：
包路径：org.geotools.referencing.CRS
类名称：CRS
方法名：parseWKT

CRS.parseWKT介绍

[英]Parses a Well Known Text (WKT) into a CRS object. This convenience method is a shorthand for the following: FactoryFinder. ReferencingFactoryFinder#getCRSFactory(null). org.opengis.referencing.crs.CRSFactory#createFromWKT(wkt);
[中]将{$0$}（WKT）解析为CRS对象。此方便方法是以下内容的简写：FactoryFinder. ReferencingFactoryFinder#getCRSFactory(null). org.opengis.referencing.crs.CRSFactory#createFromWKT(wkt);
