地理数据关联研究进展

Research progress in geographic data association

针对当前地理时空信息数据量大、利用率低的问题,基于地理数据关联的内涵,分析了现有地理空间数据关联组织模型,对多源地理空间数据关联方法的发展和研究现状进行梳理,明确地理数据关联算法的技术主线和重点内容,并在此基础上提出了下一步地理数据关联的研究方向.

In view of the problems of large amount of current geographical spatial-temporal information data and lower utilization rate of the data,and based on the connotation of geographic data association,the existing geographical spatial data association organization models are analyzed,the development and research status of multi-source geographic spatial data association methods are sorted out.The main line of technology and main content of the algorithms for geographic data association are determined,and based on this,the next research directions of geographic data association are presented.
