| Popis: | We present a simple method to enhance the view of Titan drainage networks, thus allowing extracting relevant hydrological parameters. The method uses RGB fusion of three Cassini synthetic aperture radar images acquired at different times, and is tested on one drainage network. Comparison with previous studies of the same network shows an increase in all the measured parameters. The present results help constrain previous estimates of erosion times, terrain, and tectonic models for the area and indicate that, whenever possible, geomorphological inference from drainage network geometry should be drawn on multiply sampled scenes. |
