基于云存储的空间信息服务方法

Study of spatial information service based on Hadoop

针对如何利用云存储技术提升空间地图瓦片存储与管理的可靠性,突破空间大数据服务与交互操作的瓶颈问题,该文发展了基于Hadoop的地图瓦片服务的基本框架,研究了基于HDFS的地图瓦片存储与访问模型。在GeoServer和OpenLayers开源代码的基础上,实现了基于HDFS的WMTS原型系统,通过实验验证了该方法的可行性;并对比分析了方法的访问性能,验证了该方法的可靠性及可用性。

Spatial information service is being used widely in many fields.In order to improve the reliability of cloudy spatial tiles storage and management,and to breakthrough the bottleneck of big spatial data and interactive manipulation,a Hadoop-based web map tiles service framework was discussed in this paper.And,the HDFS-based map tiles storage and access solution was probed.Furthermore,the HDFSbased WMTS protosystem was developed via GeoServer and OpenLayers, which were opensource.Lastly,the availability of the HDFS-based WMTS was completely proved,and its performance was analyzed,the reliability and availability of this method were verified as well.
