Geotk is the reference implementation of GeoAPI 3.0 interfaces. ... Geotk provides data structures for geographic data and associated metadata along with methods to manipulate those data structures.
gdal is a translator library for raster and vector geospatial data formats that is released under an X/MIT style Open Source license by the Open Source Geospatial Foundation. As a library, it presents a single raster abstract data model and single vector abstract data model to the calling application for all supported formats. It also comes with a variety of useful command line utilities for data translation and processing. The NEWS page describes the January 2017 GDAL/OGR 2.1.3 release.

Esri 在开源 apache 许可证下发布了我们的 Java 几何引擎。
https://github.com/Esri/geometry-api-java
它应该涵盖大部分您需要的（如果不是全部）几何操作。
Esri released our Java Geometry engine under the open-source apache license.
https://github.com/Esri/geometry-api-java
It should cover most, if not all, of the geometry operations that you need.
还有 Geotoolkit - 缩写为 Geotk
There is also Geotoolkit - abridged as Geotk
