Vertical Service-Oriented Conflation of Vector Spatial Data In the Spatial Data Infrastructure (SDI)

The conflation of spatial data is one important task concerning the generation of knowledge from available geoinformation Research in this domain has been carried out since the early 80s and is still one of the most challenging parts within the field of spatial data processing The range of tasks incorporates updating, change detection, enhancement and integration of spatial data.The current developments of Spatial Data Infrastructures (SDI) following the approach of Service-orientedArchitectures (SOA) foster the development of distributed geospatial information services. The fusion of thematically comparable resources to enhance available spatial information is one of the core goalsof SDI. This paper presents an approach towards ad-hoc conflations of distributed using spatial data, web services and OGC services.
