Defects should be reported using GitHub Issues.
When submitting bugs caused by particular geometries, you must submit the geometries that cause the failure, preferably in hex-encoded WKB, so that we can re-produce the failure cases.
To contribute fixes to outstanding issues, enhancements, and other smaller changes, open a pull request with your change and a fullsome description of what you are trying to achieve.
If you have any doubts as to whether your work, or planned work, is not a “smaller” change, please join the geos-devel mailing list and describe your plans. Join the list! It is a great way to get acquainted with what the development community is working on.
