Abstract

Measurement of dimensions of inaccessible objects remains a challenge in spite of new technologies available. The authors approached the problem with a photogrammetric method using a laser-camera combination installed in a helicopter. The method was applied to the topographic measurement of ice fields. It became clear that the new method will produce more reliable data on surface height and ice field mass than the previously used spot laser profilometer. The method can be developed further by using a more effective laser and by automatization of the construction of profiles.
