چکیده انگلیسی
Cassini RADAR SARtopo and altimetry data are used to construct a global gridded 1 Ã 1° elevation map, for use in Global Circulation Models, hydrological models and correlative studies. The data are sparse, and so most of the map domain (â¼90%) is populated with interpolated values using a spline algorithm. The highest (â¼+520 m) gridded point observed is at 48°S, 12°W. The lowest point observed (â¼1700 m below a 2575 km sphere) is at 59°S, 317°W: this may be a basin where liquids presently in the north could have resided in the past. If the deepest point were once a sea with the areal extent of present-day Ligeia Mare, it would be â¼1000 m deep. We find four prominent topographic rises, each â¼200 km wide, radar-bright and heavily dissected, distributed over a â¼3000 km arc in the southeastern quadrant of Titan (â¼40-60°S, 15-150°W).
