摘要
随着地理信息系统在社会各个领域的广泛应用,地理空间数据成为许多行业解决规划和管理问题不可或缺的辅助决策数据,而且对于空间数据的现势性要求越来越高。3S技术的发展也为数据快速更新提供了有效的技术手段,传统的空间数据库已无法有效地存储和管理积累的大量历史数据。本文以面向对象的地理数据库Geodatabase为基础平台,以减少历史数据存储空间为目的,完成了多基态修正模型时空数据库的设计,极大地减少了空间历史数据存储的冗余。
With the wide application of Geographic Information System in various fields of society, geospatial data has become an in. dispensable auxiliary decision-making data for many industries to solve planning and management problems, and the demand for the current situation of spatial data is becoming higher and higher. The development of 3S technology also provides an effective technical means for rapid data updating. Traditional spatial databases can not effectively store and manage a large number of accu. mulated historical data. Based on the object-oriented geographic database Geodatabase, in order to reduce the storage space of his. torical data, this paper completes the design of spatial-temporal database of multi-base state amendment model, and greatly reduc. es the redundancy of spatial historical data storage.
