Combining UAV and Landsat data to assess glacier changes on the central Tibetan Plateau
Journal of Glaciology, 2021 In recent years, researchers have focused on the applications of uncrewed aerial vehicles (UAVs) in environmental remote sensing tasks. However, studies on glacier monitoring using UAV technology are relatively scarce, especially for high mountain ...

Proceedings of the Indian National Science Academy, 2017 Polar ice is an important component of the natural system, affecting global climate on large as well as small scale. The Antarctic ice sheet has undergone significant changes in the past and governed the earth’s climatic system. This ice sheet appears to have been very dynamic and yet, not much is known about the processes involved for this dynamism ...

GLACIER SURFACE MONITORING BY MAXIMIZING MUTUAL INFORMATION [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 Abstract. The contribution of Polarimetric Synthetic Aperture Radar (PolSAR) images compared with the single-channel SAR in terms of temporal scene characterization has been found and described to add valuable information in the literature. However, despite a number of recent studies focusing on single polarized glacier monitoring, the potential of ...

Mid-Term Monitoring of Glacier’s Variations with UAVs: The Example of the Belvedere Glacier [PDF]
Remote Sensing, 2021 Recently, Unmanned Aerial Vehicles (UAV) have opened up unparalleled opportunities for alpine glacier monitoring, as they allow for reconstructing extensive and high-resolution 3D models. In order to evaluate annual ice flow velocities and volume variations, six yearly measurements were carried out between 2015 and 2020 on the debris-covered Belvedere ...

Monitoring Glacier Outburst Floods [PDF]
Hydrology Research, 1980 A review is given of the phenomenon of glacier outburst floods. Geographical distribution, modes of occurrence of glacier-dammed lakes and modes of lake-emptying are discussed. Techniques of monitoring the filling and emptying of glacier-dammed lakes are evaluated and procedures for forecasting the magnitude and frequency of floods are analyzed.

Worldwide Assessment of National Glacier Monitoring and Future Perspectives
Mountain Research and Development, 2019 It is widely accepted that glaciers are retreating throughout the world and that their decline causes serious impacts on many societies. Knowledge of glacier distribution and quantification of glacier changes is crucial to assessing the impact of glacier
