摘要
以提高地名地理实体数据自动化生产程度为切入点,充分利用矢量基础地理框架数据成果,提出了一种地名地理实体数据自动获取方法。首先结合矢量基础地理框架数据的数据分布特点,制定了合理的地名地理实体数据自动提取策略;在此基础上,针对所提取的数据集存在重复地名、同一地名的地理实体数据存储分散或被动分割等问题,通过设计有效的地名匹配策略,对同一地名进行去除重复处理,在此基础上将对应的地名地理实体数据进行归并处理;最后,结合实体数据的组织特点,建立了适合于点、线、面、多点、多线、多面、几何集合等不同类型的地名地理实体数据重组方法,实现对地名地理实体数据的空间重组。实验表明,采用所提出的方法,不仅能有效地获取地名地理实体数据,满足地名工程建设需求;而且改变了传统的数据生产模式,充分利用了现有数据成果,避免了地名地理实体数据的重复建设。该方法的提出为地名相关工程建设中地名地理实体数据的生产、更新提供了一种新思路和新方法。
Taking improving the degree of automatic production for geo-named geographical entity data as the breakthrough point and based on the vector geographic framework data resources, a method of geo-named geographical entity automatic acquisition was proposed. Firstly, combining with the characteristics of data distribution on the vectorbasic geographic framework data, a strategy of automated extraction from vector data for geo-named geographical entity was designed. Then in view of repeated place name and dispersed storage of geographical data in extracted placename data, a rule of place name matching was built to eliminate repeated redundant place name data. Finally, in allusionto the characteristics of entity data organizing, an applied algorithm of geo-named geographical entity processing wasconstructed to implement entity data fusion by data recombination for matched geo-named geographical data to get thecontent results. Through those processes, the connotation uniqueness and integrality of extracted place name information could be guaranteed. Experiments on the proposed method were performed in place name extraction and place name matching and geo-named geographical entity data recombination. The experiment results showed that the proposed method not only can effectively extract the geo-name entity data, but also change the traditional data processing mode.The method made the full use of the existing geographical data and avoided duplicate construction for geo-name geographical entity.
