Abstract
This chapter focuses on the observation of ice motion within the Earth's glaciers (ice sheets, ice caps, valley glaciers) from image feature-tracking. Observing ice flow is important for understanding glacier dynamics, their response to climate change and their future evolution. Yet, many characteristics of glaciers such as lack of image contrast or rapidly changing surface properties make the measure of surface displacement from remote sensing challenging. This chapter first highlights the main characteristics of ice flow, compared to other geophysical motion. It then describes methodologies specifically developed to measure ice flow from remote sensing imagery. Finally, it provides an overview of glaciological advances made available by remote sensing and future perspectives. Show more
