Spatial query handling in semantic web application: an experience report

Semantically capturing, storing and fetching spatial sensor web data play an important role in various cyber-physical applications. Different tools are available for each of these purposes but all of them have integration and interoperability issues of their own. In this paper, we provide a detailed comparison of different combination of tools and substantiate facts to select the right ones to seamlessly build a semantic web framework which provide effective spatial reasoning and perform semantic query over sensor web data. We also discuss various technical challenges faced during the implementation.
