Representation and reasoning with qualitative spatial relations is an important problem in
artificial intelligence and has wide applications in the fields of geographic information …

为了表达带洞区域拓扑关系, 通过扩展9 交集模型, 将9 交集矩阵的元素扩展为二进制编码,
提出了一种新的拓扑关系表达方法——D9 交集模型; 讨论了D9 交集模型的性质 …

Current models cannot distinguish detailed topological relations between regions with
holes. In order to solve this problem, a new detailed representation model for topological …

Cavities in spatial phenomena require geometric representations of regions with holes.
Existing models for reasoning over topological relations either exclude such specialized …

Topological relations are the predominant backbone of qualitative spatial reasoning,
focusing to date mostly on objects that are embedded in R 2. With the advent of ball-shaped …

Ordinary triangular mesh model can be constructed from discrete point cloud. However, this
kind of model contains large amount of data. It is not only difficult to split, but also lacks …

Multi-resolution or multi-scale spatial databases store and manage multiple representations
of spatial objects in the same area, so consistency among multiple representations of the …

In this article we show that the Voronoi-based nine-intersection (V9I) model proposed by
Chen et al.(2001, A Voronoi-based 9-intersection model for spatial relations. International …

Surrounds is a topological relation that can exist between two regions or between
collections of regions in R 2. This paper provides an algebraic construction for surrounds …

How do people reason about spatial relations? Do people with different cultural
backgrounds differ in how they reason about space? The aim of our cross-cultural study on …
