Geometry.getSRID介绍

[英]Returns the ID of the Spatial Reference System used by the Geometry.

JTS supports Spatial Reference System information in the simple way defined in the SFS. A Spatial Reference System ID (SRID) is present in each Geometry object. Geometry provides basic accessor operations for this field, but no others. The SRID is represented as an integer.
[中]返回Geometry使用的空间参照系统的ID。
JTS以SFS中定义的简单方式支持空间参考系统信息。每个Geometry对象中都有一个空间参考系统ID（SRID）。Geometry提供此字段的基本访问器操作，但不提供其他操作。SRID表示为一个整数。
