Abstract: In the multi-messenger era, connecting data from different missions is of utmost relevance. We present a new approach which allows users to produce, navigate and operate space-time coverages of any type of data: Space-Time Multi Order Coverage (STMOC). The IVOA standardized MOC system is now well established for spatial footprint coverage, and the same principles have been used to define a temporal footprint coverage (T-MOC). Until now, these two types of coverages were independent, and so their usage was limited to either space or time. But there is a clear need to connect both time and space into a unique coverage to respond the question: "where and when?". The new ST-MOC coverage system enables us to answer that question in few milliseconds for any data collection. This paper will present the scientific rationale for the ST-MOC as well as the techniques employed to enable fast production, visualisation and operations on image collections and catalogues using their ST-MOC.
