Abstract

In this paper,we propose a framework of GIS service chain for geodata and geoprocessing web services to handle complex geospatial tasks in web environment using XML web service,OGC standard and workflow techniques.An online image fusion web service is developed as an example based on the framework.This web service allows different images can be fused on-line.The prototype system integrated industry standards,including Web services,OGC WCS,OGC WPS,WSDL and BPEL4WS,allows invoke geoprocessing functionality in a platform and language independent manner on the Internet.
