These datasets are too large in size to be processed and calibrated manually as done in the past. Here, we describe a methodology to process the SAR and optical data in a synergistic fashion and automatically calibrate, mosaic, and integrate these data sets together into seamless, ice-sheet-wide, products. We employ this approach to produce annual mosaics of ice motion in Antarctica and Greenland with all available data acquired on a particular year. We find that the precision of a Landsat-8 pair is lower than that of its SAR counterpart, but due to the large number of Landsat-8 acquisitions, combined with the high persistency of optical surface features in the Landsat-8 data, we obtain accurate velocity products from Landsat that integrate well with the SAR-derived velocity products. The resulting pool of remote sensing products is a significant advance for observing changes in ice dynamics over the entire ice sheets and their contribution to sea level. In preparation for the next generation sensors, we discuss the implications of the results for the upcoming NASA-ISRO SAR mission (NISAR).<\/jats:p>","DOI":"10.3390\/rs9040364","type":"journal-article","created":{"date-parts":[[2017,4,12]],"date-time":"2017-04-12T10:15:06Z","timestamp":1491992106000},"page":"364","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":236,"title":["Comprehensive Annual Ice Sheet Velocity Mapping Using Landsat-8, Sentinel-1, and RADARSAT-2 Data"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9155-5455","authenticated-orcid":false,"given":"Jeremie","family":"Mouginot","sequence":"first","affiliation":[{"name":"Department Earth System Science, University of California Irvine, CA 92697, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3366-0481","authenticated-orcid":false,"given":"Eric","family":"Rignot","sequence":"additional","affiliation":[{"name":"Department Earth System Science, University of California Irvine, CA 92697, USA"},{"name":"Jet Propulsion Laboratory, Pasadena, CA 91109, USA"}]},{"given":"Bernd","family":"Scheuchl","sequence":"additional","affiliation":[{"name":"Department Earth System Science, University of California Irvine, CA 92697, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7987-1305","authenticated-orcid":false,"given":"Romain","family":"Millan","sequence":"additional","affiliation":[{"name":"Department Earth System Science, University of California Irvine, CA 92697, USA"}]}],"member":"1968","published-online":{"date-parts":[[2017,4,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"416","DOI":"10.3189\/002214310792447734","article-title":"Greenland flow variability from ice-sheet-wide velocity mapping","volume":"56","author":"Joughin","year":"2010","journal-title":"J.
