dc.description.abstractEnSince the begining of the data collection of the Cassini-Huygens Mission in 2004, strong evidences of liquid areas on the Titan's surface near the poles, from small isolated rounded lakes, filled or not by liquids, to dendritic large seas, suggest that Titan experiences an active hydrocarbon cycle, in a way similar to the water cycle on the Earth. Precipitation, evaporation and condensation of hydrocarbon compounds should occur on this icy satellite and observation of lake-like features at different times will help our understanding of this cycle. Ontario Lacus, the major lake in the whole southern hemisphere, has been imaged by the Cassini spacecraft instruments since the first Titan encounter T0 in July 2004. During these 5 years lapse time, the Imaging Science Subsystem (ISS), the Visual and Infrared Mapping Spectrometer (VIMS) and the different parts of the RADAR instrument (SAR Imaging, altimeter and radiometer) acquired data sets which can highlight many properties of the surface into and around the Titan's lakes using Ontario Lacus as an example. In this study, we take advantages of each imaging data set to establish a global survey of Ontario Lacus environment from 2005 to 2009, to determine whether or not surface changes occured during this time interval, and make a geomorphological cartography of the lake, using a comparison of the VIMS T51 new data set (acquired in March 2009) and the RADAR SAR images.
