In coming years we will see an explosion in our need to routinely perform a complex multi-viewpoint data analysis of space physics data sets. Orchestrated multi-spacecraft measurements open access to new physical quantities not accessible with single spacecraft, and they remove spatio-temporal ambiguities. Our ability to appropriately analyze data from three-dimensional spacecraft formations and the proper ingestion of those data into models is currently underdeveloped. Providing comprehensive data fusion tools for these new data sets is necessary in order to utilize these data effectively. We are presenting our system, currently under development, which is designed to give full access to the three-dimensionality of the space environment by calculating gradients, divergences and curls from measurement of vector and scalar quantities performed simultaneously by identical instruments on multiple satellites. On the local level this allows to obtain spatial or temporal scales at high resolution and on a global level this reduces the amount of data considerably and facilitates the interface with global numerical models.
