Discovery is an art, at least if the desired object is more complex than a simple blog web-page such as this one. Here we are talking about discovery of Earth Observation (EO) products, services providing on-demand processing capabilities, and applications that are not deployed yet but waiting in an application store for their ad-hoc deployment and execution.
Instead of processing ever-increasing amounts of data locally, these applications are transferred to where the data resides. But how to discover these applications? How to understand what data an application can be applied to? How to chain applications? How to combine applications with already deployed services that provide data and data processing capabilities? All these aspects are now in focus of OGC Testbed-15.
