Ground control points for investigating mass loss processes on Khumbu Glacier, Nepal (NERC grant NE/L002574/1)

These data consist of a spreadsheet containing 557 ground control points (GCPs) collected in the Everest region of Nepal between October 2015 and October 2016. GCPs were collected using a Leica GS10 differential Global Positioning System (dGPS), post-processed against base station data at Syangboche. These final data have sub-centimetre accuracy (in x, y and z) in all cases. Point positions are heavily concentrated around meltwater ponds on the glacier surface, and prominent features around the glacier margin. These data will be used by PhD students and staff in the School of Geography, University of Leeds, to provide ground control for fine-resolution satellite imagery and Structure-from-Motion surveys to assess mass loss processes on Khumbu Glacier.

Statement

557 ground control points (GCPs) collected around Khumbu and Ama Dablam Glaciers during field campaigns in October/November 2015, May/June 2016, and October 2016. GCPs were collected using Leica GS10s in rapid-static mode. GCPs were surveyed in a non-uniform pattern along the margins of respective glaciers or on the surface. GCPs on the margin of glaciers were collected on large boulders or path junctions. Those collected on the glacier were marked using temporary markers for inclusion into a SfM workflow. Base station data were post-processed against the Syangboche permanent station (UTM 45N 471683 m E, 3076653 m N) located ~ 20 km from our field site using Global Positioning System (GPS) and GLObal NAvigation Satellite System (GLONASS) satellites. Our field GCPs were then adjusted with reference to the field base station data following a relative carrier phase positioning strategy. Elevations are to Earth Gravitational Model 2008 (EGM2008).
