摘要

定性空间推理的RCC理论能够比较全面地表达空间对象的拓扑关系.但由于不支持混合维空间对象

RCC不能直接用于空间查询.本文扩展了RCC

建立了能表达混合维空间关系

更适合于空间查询的空间关系模型MRCC.该模型采用GIS中常用的数据结构

支持混合维空间对象的全拓扑(mereotopology)关系

并根据混合维对象的特点建立了与维数无关的统一的方向、距离关系.利用该模型扩充了标准SQL语言的关系代数

实现了混合维定性空间查询语言MQS-SQL.

Abstract

The RCC theory of qualitative spatial reasoning which completely express the topology of spatial objects couldn't be directly appled to spatial query

because it can not support multi-dimension. We extend the RCC and build a spatial query oriented spatial relation model MRCC with mufti-dimensional objects supported. This model follows the common data structure of GIS

supports mufti-dimensional mereotopology relation and dimension independent union direction and distance relations. We improve the algebra of standard SQL with this spatial relation model

design and implement a mufti-dimensional qualitative spatial query language MQS-SQL.
