spatiotemporal database

基本解釋

In spatiotemporal database, geographic entity model includes spatial and temporal information of geographic object.
在時(shí)空數(shù)據(jù)庫中，地理實(shí)體模型包括地理對(duì)象空間信息和時(shí)態(tài)信息。
This paper introduces two methods to construct topographic map spatiotemporal database:current state keeping form and data appending form.
介紹了實(shí)際工作中經(jīng)常遇到的地形圖時(shí)空數(shù)據(jù)建庫方法：保持現(xiàn)狀式和數(shù)據(jù)追加式。
The previous researches on spatiotemporal databases were concentrated on data models and languages, they are not the implementation of spatiotemporal database systems.
已有的時(shí)空數(shù)據(jù)庫研究集中在模型和語言上，缺乏時(shí)空數(shù)據(jù)庫的系統(tǒng)實(shí)現(xiàn)。
