One GUI to Rule Them All: Accessing Multiple Semantic EO Data Cubes in One Graphical User Interface

Spatio-temporal analysis capabilities of big Earth observation (EO) data are possible now on various infrastructures, but the transferability and interoperability analyses remain challenging. This contribution describes an approach for interacting with multiple semantic EO cubes, where each observation, at least one nominal (i.e., categorical) interpretation is available can be queried in same instance. Our in-house developed Web-based graphical user interface (GUI) provides technical access to regardless what infrastructure they implemented on. It designed create models using a language, inference engine able evaluate these against existing cubes based user’s defined area timespan interest. Querying level allows across cubes. shows towards solving this open research gap discusses relevant challenges such as models, on-demand instantiation, federated We believe that offers new opportunities improved syntactic better positioned allow semantically-enabled queries cube context.
