Ice thicknesses at the glacier outline of 2013 identified by satellite imagery was set to zero. Bed topography elevations were calculated by subtracting ice thickness values from ice surface elevations. These data were then interpolated using a triangulated irregular network to obtain a continuous subglacial topography of the caldera. Due to the irregular distribution of ice thickness measurements, four steering points were added in less surveyed areas to guide the interpolation and to achieve a more realistic subglacial caldera topography. The topography model was calculated in a resolution of 30 m and is available in GeoTIFF format using projection WGS 84 / UTM zone 19S (EPSG:32719).
