locality spatial data的意思|示意

Spatial queries are one of the best examples to show locality of data access, in other words, geometries that are close to each other in the real world are often accessed together.

空间查询是展示局部数据访问(换句话说，现实中临近的几何图形常常被一起访问)的最好例子之一。

Then a new projection-delamination technique for optimizing spatial locality is presented, and a data transformation framework based on this technique is brought forward.

该框架主要利用投影技术来优化数据访问的空间局部性，并同时利用数据分层技术来解决因投影而带来的数据重叠问题。
