We conducted long-term continuous positioning monitoring of barchan dunes using RTK equipment and wind regime monitoring in the Sanlongsha dune field, which is located in the northern part of China\u2019s Kumtagh Desert. We analyzed the wind energy environment of the study area, the migration characteristics of different positions in the barchan dune, and dune shape changes during different periods. We found that (1) comparing the differences in migration distance and direction measured at six positions in the barchan, there existed variations in barchan migration across these positions. (2) The shape changes at the left horn, right horn, and windward slope of barchans were larger than at the center of the leeward toe and brink, so the estimates based on measurements at these four positions had a weaker fit with the resultant drift potential (RDP) and a greater difference from the resultant drift direction (RDD). (3) The shape of the leeward slope on the barchan did not change much during dune migration, so the center of the leeward toe and brink measurements were closer to the actual dune migration distance and direction. Thus, we recommend using the center of the leeward toe or brink as the optimal measurement points to monitor barchan dune migration. This study will provide a reference for the more accurate measurement of barchan dune migration.<\/jats:p>","DOI":"10.3390\/rs15194728","type":"journal-article","created":{"date-parts":[[2023,9,27]],"date-time":"2023-09-27T07:38:46Z","timestamp":1695800326000},"page":"4728","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Real-Time Kinematic Positioning (RTK) for Monitoring of Barchan Dune Migration in the Sanlongsha Dune Field, the Northern Kumtagh Sand Sea, China"],"prefix":"10.3390","volume":"15","author":[{"given":"Xuegang","family":"Xing","sequence":"first","affiliation":[{"name":"School of Geography and Resource Science, Guizhou Provincial Key Laboratory of Geographic State Monitoring of Watershed, Institute of Guizhou Mountain, Guizhou Education University, Guiyang 550018, China"}]},{"given":"Zhuanling","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Geography and Resource Science, Guizhou Provincial Key Laboratory of Geographic State Monitoring of Watershed, Institute of Guizhou Mountain, Guizhou Education University, Guiyang 550018, China"}]},{"given":"Guangqiang","family":"Qian","sequence":"additional","affiliation":[{"name":"Key Laboratory of Desert and Desertification, Northwest Institute of Eco-Environment and Resources, Chinese Academy of Sciences, Lanzhou 730000, China"}]},{"given":"Guanghong","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Geography and Resource Science, Guizhou Provincial Key Laboratory of Geographic State Monitoring of Watershed, Institute of Guizhou Mountain, Guizhou Education University, Guiyang 550018, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,27]]},"reference":[{"key":"ref_1","unstructured":"Bagnold, R.A.
