本文整理了Java中org.geotools.referencing.CRS类的一些代码示例，展示了CRS类的具体用法。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类的具体详情如下：
包路径：org.geotools.referencing.CRS
类名称：CRS

CRS介绍

[英]Simple utility class for making use of the CoordinateReferenceSystem and associated org.opengis.referencing.Factory implementations. This utility class is made up of static final functions. This class is not a factory or a builder. It makes use of the GeoAPI factory interfaces provided by ReferencingFactoryFinder.

The following methods may be added in a future version:

  • CoordinateReferenceSystem parseXML(String)

When using CoordinateReferenceSystem matching methods of this class ( #equalsIgnoreMetadata(Object,Object), #lookupIdentifier(IdentifiedObject,boolean), #lookupEpsgCode(CoordinateReferenceSystem,boolean), #lookupIdentifier(IdentifiedObject,boolean), #lookupIdentifier(Citation,CoordinateReferenceSystem,boolean)) against objects derived from a database other than the official EPSG one it may be advisable to set a non zero comparison tolerance with Hints#putSystemDefault(java.awt.RenderingHints.Key,Object) using the Hints#COMPARISON_TOLERANCE key. A value of 10e-9 has proved to give satisfactory results with definitions commonly found in .prj files accompaining shapefiles and georeferenced images.
Warning: the tolerance value is used in all internal comparison, this will also change the way math transforms are setup. Use with care.
[中]用于使用CoordinateReferenceSystem和关联组织的简单实用程序类。opengis。参考。工厂实现。此实用程序类由静态final函数组成。此类不是工厂或生成器。它利用了ReferenceGFactoryFinder提供的GeoAPI工厂接口。
未来版本中可能会添加以下方法：
*坐标引用系统解析XML（字符串）
使用此类的CoordinateReferenceSystem匹配方法时（#equalsIgnoreMetadata（Object，Object），#lookupIdentifier（IdentifiedObject，boolean），#lookupEpsgCode（CoordinateReferenceSystem，boolean），#lookupIdentifier（IdentifiedObject，boolean），#lookupIdentifier（引文、坐标引用系统、布尔值））针对从官方EPSG one以外的数据库派生的对象，建议使用提示#比较#容差键设置带有提示#putSystemDefault（java.awt.RenderingHints.Key、Object）的非零比较容差。10e-9的值已证明能给出令人满意的结果，其定义通常在中找到。包含形状文件和地理参考图像的prj文件。
警告：公差值用于所有内部比较，这也将更改数学变换的设置方式。小心使用。
