The enormous quantity and complexity of planetary data acquired by spacecraft during the last two decades has created a demand within the planetary community for access to the raw and high level data archives and to the tools necessary to analyze these data. The number and the size of the datasets are so large that an information system to process, manage and distribute data is critical. In this framework, the Observatories of Paris Sud (OSUPS) and Lyon (OSUL) have recently developed a portal, called PSUP (Planetary SUrface Portal), to provide users with efficient and easy access to these data products.
