摘要 数据的现势性是土地资源数据的生命力所在,为此必须研究快速、准确、高效的数据更新方法。针对不同类型的土地资源数据,本文分别对基于版本和基于要素空间拓扑关系两种更新方法进行了探讨和研究。通过珠海市土地资源数据管理系统检验表明这两种方法是行之有效的。 The current state of data is the vitality of land resource data,for this reason timely,exact and effective methods of data updating are urgently needed.As different kinds of data of land resource,the updating methods based on version and on the topological relation of feature respectively were discussed and proposed in the paper,and the updating was proved to be valid.
