Towards a semantic-based automatic orchestration of geo-processing services

摘要

Many reasons may call for an orchestrated response computation to some geo service request: distributed data; specialized services (such as reprojection) are not available on the node addressed; heavy-weight jobs suggest distributed processing; and several more. Typically such orchestrations today are performed manually in advance. When it comes to the particularly interesting case of heavy-weight services, such as defined by the OGC Web Processing Service (WPS), it turns out very difficult at least to find methods for an automatic orchestration.
