面向服务的遥感数据在线处理方法

Implementation of Service-oriented Online Remote Sensing Image Data Processing

通过对遥感影像数据的在线数据处理的实现展开研究,提出了面向服务的遥感数据在线挖掘与信息分析方法,以基于标准OGC规范的Web服务方式和基于BPEL的工作流引擎提供空间信息服务链应用,实现了在线投影变换、基本统计和直方图分析、变化检测分析、空间聚类分析和空间关联分析等基本遥感数据挖掘与信息分析工具。本方法具有可描述、弱耦合、灵活适应各种数据格式、处理进程在客户端可监控等特点。

This paper focuses on remote sensing image data processing and presents implementation of a service-oriented online remote sensing image data mining and analysis. OGC specifications and BPEL-based workflow engine provide the capacities of using geospatial information service chain to achieve projection transformation,basic statistics and histogram analysis,change detection analysis,spatial cluster analysis,remote sensing image data mining and related geospatial processing tools. The implementation is normalized described,weak coupling,and flexible to a variety of data formats,and has process monitoring function in the client side.
