Surface elevations on Qaanaaq and Bowdoin Glaciers in northwestern Greenland as measured by a kinematic GPS survey from 2012–2016
Kinematic GPS measurements provide in-situ data crucial for measuring the surface elevation change of glaciers. Owing to their accuracy, which is generally better than half meter, surface elevations derived from kinematic GPS surveys are useful and essential for generating precise digital elevation...
