Recent progress on Web service technology may provide a solution to current problems in using remote sensing data. This paper presents a prototype geospatial Web service system to demonstrate the advantages of such a system over the traditional non service-based systems for reducing the difficulty of using remote sensing data for research and applications.(More)
Geospatial data availability, interoperability, and integration remain a problem today. Current spatial data infrastructures (SDIs) are of limited use particularly to non-expert user communities. GeoBrain, a NASA funded project, has aimed to address those challenges, facilitate easy use of geospatial data and overcome some limitations of current SDIs(More)
—GeoBrain is a Web based geospatial information and knowledge system that adopts and implements the newly emerged geospatial Web service technologies. It provides innovative methods in remote sensing education to prepare students with world-view training and experiences, transfer spatial data and information technologies to the professional workforce and(More)
Since the Open Geospatial Consortium (OGC) proposed the geospatial Web Processing Service (WPS), standard OGC Web Service (OWS)-based geospatial processing has become the major type of distributed geospatial application. However, improving the performance and sustainability of the distributed geospatial applications has become the dominant challenge for(More)
