分布式地理数据库在核心要素更新中的应用

Application of Distributed Geodatabase in Core Elements Update

为了维持“天地图·福建”的现势性,需要每年对核心要素数据进行更新。在核心要素数据更新的过程中,数据主要以文件进行流转,更新完成后需要再导入数据库进行服务发布,影响更新的效率。将分布式地理数据库用于核心要素数据更新,制定了数据更新的流程,并对更新流程进行耗时分析,该更新流程能够节省时间。更新成果存储在数据库中,不需要导入数据库就可以用于发布服务等应用,提高了效率。

In order to maintain the data currency of "MapWorld · Fujian", the core element data must be updated at least once a year. During the update process of core element data, the data are mainly transferred by files, which affect the efficiency of the update. When the update is complete, the data need to be imported into the database for service publishing. In this paper, we developed an update technical process based on distributed geodatabase, and carried out timeconsuming analysis of the updated process. The result proves that the update method based on distributed geodatabase can save time. The updated results are stored in the database and can be used directly for applications such as publishing services, which can improve efficiency.
