Multipoint measurements in space open a question of data visualization because the

traditional techniques are not sufficient for analyzing the new quality of data

provided by the four Cluster spacecraft. We demonstrate how Cluster data can be

visualized in 3D with Orbit Visualization Tool (OVT). The data can be plotted

along the orbit, on the fieldlines crossed by the satellite, or on the ionospheric

footprints together with the global magnetospheric structure. A possiblity to

interractively browse through the data and see configuration of the cluster of

satellites, magnetic field topology, spin axis orientation, etc., makes OVT a

powerfull tool for both studying and presenting the data. The homepage for Orbit

Visualization Tool is http://ovt.irfu.se.
