Towards a Quality Aware Web Processing Service

Quality information is essential to determine the fitness for use of spatial data and furthermore to correctly interpret the results of spatial analyses. Up to now this aspect is still not sufficiently included in geospatial applications and geospatial web services. This paper discusses a concept for a Web Service with the ability to dynamically generate quality information for the results of spatial analyses by taking into account the quality of the input data. The concept is based on the current ISO quality and metadata standards and OGC web service standards. An implemented prototype together with a use case from forestry shows the practicability and relevance of this concept.      «
