基于基态修正时空模型的行政区划图更新方法研究

The Method of Administrative Map Update Based on Spatial-temporal Data Model of Base State with Amendments

随着地理信息系统在我国日常生活中的广泛应用,数据不易获取的问题越发突出,特别是行政区划图这种变更频繁、标准制图周期长的数据。根据我国行政编码的规范和行政区划变更特点,在基态修正模型的基础上采用面向对象的方式组织空间数据,通过对行政区划变更事件的记录,生成新的行政区划图,并在此基础上实现空间数据的管理和回溯查询,解决了空间数据需求的现势性问题。

With the wide application of geographical information systems in our daily life,the acquisition of spatial data,such as administrative map that was drawn up after a long period and changed frequently,is becoming more difficult.According to the national administrative code criterion and the particularity of administrative division readjustment,this paper introduced an object-oriented approach to organize spatial data based on data model of base state with amendments and created a new administrative map by recording change events of administrative division readjustment.This method helps to realize the management and backtracking query of spatial data and solve its real-time issue.
