Paper Abstract

Spatial Information Multi-grid (SIMG) is regarded as a new method of spatial information expression considering the characters of nature and attributes of society. The focus of this paper is on a dynamic spatio-temporal expression for spatial information based on the framework of SIMG. Traditional Spatio-temporal Data Models (STDMs) lack enough abilities to meet the requirements of expressing and organizing spatial information based on the framework of SIMG. In this paper, the three characters (space, attribute, time) of SIMG spatial features are studied, systematic classification of spatio-temporal changes of SIMG spatial feature are described, and a Spatio-temporal Semantic Model based on SIMG is proposed.
