摘要
随着数字城市地理空间框架建设的全面推进,我国已在建与建成运行的数字城市约600个,为确保数据的现势性,建立数字城市的数据更新机制至关重要。本文根据数字城市数据体系,从"建立更新模式""数据源获取机制""更新内容及周期""更新技术研究"四个方面,探讨了数字城市数据更新机制,并提出了参考建议,可以为数字城市地理空间框架建设的后续维护与管理提供参考。
With the comprehensive moving forward of the Digital City Geospatial Framework , China has been about 600 Digital City Geospatial Framework in building or completed .In order to ensure Digital City Geospatial Framework data ’s freshness, establishing digital city data update mechanism is very important .According to the data of digital city system , This paper research the data update mechanism which Contains ＆quot;build updating mode ＆quot;,＆quot;data source acquisition mechanism＆quot;,＆quot;update content and cycle＆quot;,＆quot;update tech-nology＆quot;four aspects , and also bring some suggestions , which can provide reference for the Management and Maintenance of digital cit -y geospatial framework .
