Java商业友好的R-tree实现？

问题描述

我需要商业友好型（Apache许可证，LGPL，Mozilla公共许可证等），以便将 Web服务替换为时区，如问题。我已 ，但我想知道如果有人在实践中评估或使用过它们。

I need a commercial-friendly (Apache Licence, LGPL, Mozilla Public License etc) R-tree implementation in Java, in order to substitute the geonames Web Service for timezones, as suggested in the question "Determine timezone from latitude/longitude without using web services like Geonames.org". I have found some around, but I was wondering if someone has evaluated or used them in practice.
