基于POI的基础地理信息数据库点状要素更新方法研究

Research on Point Feature Updating Method of Basic Geographic Information Database Based on POI

近年来,我国国民经济建设与社会发展对基础地理信息数据的时效性和多元化需求日益迫切。与此同时,随着互联网、大数据、人工智能等新一代信息技术与测绘地理信息技术的融合,传统以数据库为更新对象、以年为更新周期的批次化动态更新,将逐步发展为以地理要素为更新对象、以天为更新周期的应需实时动态变化检测[1]。本文选取互联网地图大数据中较为典型的POI数据为重点研究对象,提出了基于POI的基础地理信息数据库点状要素更新方法,为基础地理信息数据实时动态更新提供了新思路。

In recent years,China′s national economic construction and social development have become increasingly urgent for the timeliness and diversification of basic geographic information data.At the same time,with the integration of new generation information technology such as the Internet,big data,artificial intelligence and mapping and geographic information technology,the traditional batch update and update with the database as the update target will gradually develop into Geographical elements are updated objects,real-time dynamic change detection in the day of the update cycle[1].This paper selects the typical POI data in the Internet map big data as the key research object,and proposes the POI-based basic geographic information database point element update method,which provides a new idea for the real-time dynamic update of the basic geographic information data.
