Beschreibung:
Here, we present a methodology which can automatically calibrate, mosaic, and post-process Landsat images into displacement maps, resulting in seamless, continent-wide, ice velocity products. Using this developed methodology, we have assembled over 200,000 displacement maps to generate Antarctic-wide annual mosaics of ice velocity maps from more than 70,000 Landsat 8 images acquired between December 2013 and April 2019. The new suite of annual Antarctic ice velocity maps at 105-m grid spacing provide the clearest picture of Antarctic-wide ice flow to-date, and error analysis via comparisons with various available prior ice velocity data products and in situ data confirmed the improved accuracy of this new data product.
