Zusammenfassung |
Remotely sensed glaciological measurements can be expensive, often involving
a trade-off between resolution, scale, and frequency. We report on a case
study in which two low-cost techniques were used to generate digital
elevation models and orthomosaics of an Arctic glacier in consecutive
ablation seasons. In the first aerial survey we used an unmanned aerial
vehicle and acquired images autonomously. The following year we took
advantage of the helicopter used for site access, and were able to acquire
images manually, for little additional helicopter time. We present a
preliminary assessment of accuracy and apply these data to measure glacier
thinning and motion. |
