Glacier surface elevation measurements of the caldera glacier of Volcán Sollipulli. Data was gathered in February 2011 along three tracks across the glacier using differential GNSS with a base station installed on bedrock nearby. Measurements were made for every 2 m along these tracks. The accuracy of each measurement is estimated to be better than 20 cm. Measurements are provided in geographic coordinates (WGS84) with altitudes as ellipsoidal heights.
