Ice velocity is a direct and essential indicator of the stability of Antarctic ice sheet in response to global climate change. It is also one of the crucial data to accurately estimate the contribution of the Antarctic ice sheet to global sea level rise. Optical remote sensing imagery is an important data source for large-scale extraction of Antarctic ice velocity because of the advantages of data acquisition in fine temporal and spatial resolution. In this paper, we review the existing methods of Antarctic ice velocity reconstruction by using optical images, introduce relevant software and tools, and summarize Antarctic ice velocity products generated based on optical remote sensing images from 1960s to present. Furthermore, we demonstrate applications of the ice velocity products in some typical areas, such as mass balance evaluation, long time series changes monitoring of ice shelves, etc. Finally, the advantages and future development trends of optical remote sensing images for Antarctic ice velocity reconstruction are summarized.
