The key definitions of spatio-temporal data modeling are summarized and the requirements of spatio-temporal database community, including temporal semantics, spatial semantics, spatio-temporal semantics and query capabilities are specified 摘要闡述了時空數(shù)據(jù)建模的主要定義,分析了時空數(shù)據(jù)庫領(lǐng)域的建模需求,包括時態(tài)語義、空間語義、時空語義和查詢能力。
