CITI-SENSE data flow model which is established as a profile of the standardised (OGC, ISO) WFS service conformant with the GEOSS infrastructure. Observations can be accessed and transformed to different data formats (e.g., XML, JSON, CSV, etc.) and visualised through different visualisations widgets with HTML5 being used for the portability for both web portals and apps. Current experiments are evaluating big data scalability with respect to data volume and velocity/speed.
