基于基态修正时空模型的行政区划图更新方法研究

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。

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

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 re...
