Natural-Language Description of Spatio-temporal Relationships between Moving Points and Reference Features
Zhang Cai-l · Geography and Geo-Information Science · 2015
Modeling spatio-temporal relationships between moving objects is of great significance for spatio-temporal queries,spatio-temporal analysis and reasoning.Based on the slice representation of moving point′s trajectory,a novel method is proposed to describe the spatio-temporal topological relationships between a moving point and reference feature.At the same time,an integrated framework is presented for the representation of spatio-temporal relationships between moving points and reference features according to the description rules of natural language,where the topological,directional and distance relations between moving points and reference features are considered together.Finally,a case study is provided to demonstrate the application and feasibility of the proposed method in this paper.
