一个双时态二维空间索引模型

A bitemporal 2D-spatial index

提出了一种基于 2R树的双时态二维空间索引模型BT2D Index.该模型是依据降维的思想将双时态索引 2R树和基于事务时间的时空索引 2R树整合而成的 ,给出了BT2D Index的 2R树实现模型 ,以及查询、插入、删除和更新等索引操作的思想方法 .BT2D Index尤其适合于当前版本索引比例较大的双时态二维空间索引 .

Bitemporal 2D-spatial index—BT2D-Index was proposed based on 2R-Tree. BT2D-Index was integrated with the Bitemporal index and Spatiotemporal index based on transaction time. This is derived from the idea “decrease dimension”. The implementation model and the indexing methods were given. BT2D-Index is of great use when there are more indexing operations on current version.
