Most previous studies have used static threshold techniques to detect snow cover, which can lead to errors such as misclassification of snow and clouds, because the reflectance of snow cover exhibits variability and is affected by several factors. Therefore, we present a simple new algorithm for mapping snow cover from Moderate Resolution Imaging Spectroradiometer (MODIS) data using dynamic wavelength warping (DWW), which is based on dynamic time warping (DTW). DTW is a pattern recognition technique that is widely used in various fields such as human action recognition, anomaly detection, and clustering. Before performing DWW, we constructed 49 snow reflectance spectral libraries as reference data for various solar zenith angle and digital elevation model conditions using approximately 1.6 million sampled data. To verify the algorithm, we compared our results with the MODIS swath snow cover product (MOD10_L2). Producer\u2019s accuracy, user\u2019s accuracy, and overall accuracy values were 92.92%, 78.41%, and 92.24%, respectively, indicating good overall classification accuracy. The proposed algorithm is more useful for discriminating between snow cover and clouds than threshold techniques in some areas, such as those with a high viewing zenith angle.<\/jats:p>","DOI":"10.1155\/2017\/4820905","type":"journal-article","created":{"date-parts":[[2017,11,21]],"date-time":"2017-11-21T18:31:20Z","timestamp":1511289080000},"page":"1-15","source":"Crossref","is-referenced-by-count":11,"title":["New Approach for Snow Cover Detection through Spectral Pattern Recognition with MODIS Data"],"prefix":"10.1155","volume":"2017","author":[{"given":"Kyeong-Sang","family":"Lee","sequence":"first","affiliation":[{"name":"Division of Earth Environmental System Science, Major of Spatial Information Engineering, Pukyong National University, Daeyeon-3 Nam-Gu, Busan 608-737, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Donghyun","family":"Jin","sequence":"additional","affiliation":[{"name":"Division of Earth Environmental System Science, Major of Spatial Information Engineering, Pukyong National University, Daeyeon-3 Nam-Gu, Busan 608-737, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2321-731X","authenticated-orcid":true,"given":"Jong-Min","family":"Yeom","sequence":"additional","affiliation":[{"name":"Korea Aerospace Research Institute (KARI), 169-84 Gwahak-ro, Yuseong-gu, Daejeon 305-806, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minji","family":"Seo","sequence":"additional","affiliation":[{"name":"Division of Earth Environmental System Science, Major of Spatial Information Engineering, Pukyong National University, Daeyeon-3 Nam-Gu, Busan 608-737, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sungwon","family":"Choi","sequence":"additional","affiliation":[{"name":"Division of Earth Environmental System Science, Major of Spatial Information Engineering, Pukyong National University, Daeyeon-3 Nam-Gu, Busan 608-737, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jae-Jin","family":"Kim","sequence":"additional","affiliation":[{"name":"Division of Earth Environmental System Science, Major of Environmental Atmosphere Sciences, Pukyong National University, Daeyeon-3 Nam-Gu, Busan 608-737, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5031-0256","authenticated-orcid":true,"given":"Kyung-Soo","family":"Han","sequence":"additional","affiliation":[{"name":"Division of Earth Environmental System Science, Major of Spatial Information Engineering, Pukyong National University, Daeyeon-3 Nam-Gu, Busan 608-737, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1175\/1520-0469(1989)046<1002:REBITC>2.0.CO;2"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1175\/1520-0442(1991)004<0689:TEOSCO>2.0.CO;2"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1126\/science.263.5144.198"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.3390\/rs8120981"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.3390\/s110807678"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1007\/s13280-011-0212-y"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1016\/0034-4257(95)00137-P"},{"issue":"6","key":"8","volume":"109","year":"2004","journal-title":"Journal of Geophysical Research D: Atmospheres"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1175\/1520-0469(1976)033<2461:AARBES>2.0.CO;2"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1029\/WR025i007p01505"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1099-1085(199808\/09)12:10\/11<1723::AID-HYP691>3.0.CO;2-2"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1080\/01431160500206635"},{"key":"13","year":"2007","journal-title":"Climate Change, The Physical Science Basis.
