CRS.lookupEpsgCode介绍

[英]Looks up an EPSG code for the given CoordinateReferenceSystem). This is a convenience method for #lookupIdentifier(Citations,IdentifiedObject,boolean)( Citations#EPSG, crs, fullScan) except that code is parsed as an integer.
[中]查找给定坐标引用系统的EPSG代码）。这是#lookupIdentifier(Citations,IdentifiedObject,boolean)( Citations#EPSG, crs, fullScan)的一种方便方法，只是代码被解析为整数。
