Abstract [en]

The glacial geomorphology of the central Tibetan Plateau was mapped over 285,000 km2. We here present a map covering 135,000 km2 at a scale of 1:660,000. The glacial geomorphology was mapped using 15 and 30 m resolution Landsat 7  ETM+ satellite imagery, a 90 m resolution  SRTM digital elevation model, and Google Earth imagery. Four landform categories were discernible and mapped; glacial valleys, marginal moraines, glacial lineations, and hummocky terrain. While these landforms are abundant in and around high mountain areas, extensive (248,000 km2) surrounding lower-lying plateau surfaces lack a glacial landform record. The mapped landforms indicate multiple glacial advances of valley and piedmont glaciers. The mapped landform record lends no support to  individual ice centres having coalesced to form a past plateau-wide ice sheet.
