城市地理空间大数据建设的关键技术研究

Research on Key Technologies of Urban Geospatial Big Data Construction

随着城市化进程的加快,城市地理空间数据呈现爆炸式的增长,且城市地理空间数据来源多样、数据标准不一,提取和整合城市空间数据是当前迫切需要解决的问题。本文从数据基准、基础框架数据的制作、数据库设计等方面进行了研究,并就关键技术的实现方式列举出相关应用实例,拟为大数据的挖掘和分析提供一些思路和方法。

With the acceleration of the urbanization process,urban geospatial data is experiencing explosive growth,the sources of urban geospatial data are diverse,and data standards are different.Extracting and integrating urban spatial data is an urgent problem that needs to be solved.This paper fucuses on the production of basic frame data,database design and other aspects,and relevant application examples on the implementation of key technologies.It is proposed to provide some ideas and methods for big data mining and analysis.
