With special long and narrow geographical location in the area, designing and building monitoring network was vital to the realization of landslide monitoring. To build such a network with high precision, this paper mainly focused on the following four aspects: (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mrow><mml:mn fontstyle=\"italic\">1<\/mml:mn><\/mml:mrow><\/mml:math>) method of using multiple GPS reference stations to build a unified datum network and subnet adjustment, (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\"><mml:mrow><mml:mn fontstyle=\"italic\">2<\/mml:mn><\/mml:mrow><\/mml:math>) GPS data processing algorithm with millimeter level, (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M3\"><mml:mrow><mml:mn fontstyle=\"italic\">3<\/mml:mn><\/mml:mrow><\/mml:math>) analysis of influence on the adjustment resulting from systematic error of time evolution datum from different GPS observations, and (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M4\"><mml:mrow><mml:mn fontstyle=\"italic\">4<\/mml:mn><\/mml:mrow><\/mml:math>) establishment and stability analysis of unified datum. Then, using global test and trial-and-error method to analyze the datum based on the GPS observations (2008~2011) of landslide monitoring network in the area, we concluded that there were moved reference points during the three years of high water impoundment, and the horizontal displacement of moved reference points was more than 4\u2009cm, even up to 79.4\u2009cm. The displacement direction of unstable reference points was inspected with geographical environment at sites, which revealed congruency between them.<\/jats:p>","DOI":"10.1155\/2017\/9819214","type":"journal-article","created":{"date-parts":[[2017,9,20]],"date-time":"2017-09-20T21:02:23Z","timestamp":1505941343000},"page":"1-13","source":"Crossref","is-referenced-by-count":7,"title":["Landslide Monitoring Network Establishment within Unified Datum and Stability Analysis in the Three Gorges Reservoir Area"],"prefix":"10.1155","volume":"2017","author":[{"given":"Shengxiang","family":"Huang","sequence":"first","affiliation":[{"name":"School of Geodesy and Geomatics, Wuhan University, Wuhan 430079, China"},{"name":"Collaborative Innovation Center for Geospatial Technology, Wuhan 430079, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4885-5097","authenticated-orcid":true,"given":"Chenfeng","family":"Li","sequence":"additional","affiliation":[{"name":"School of Geodesy and Geomatics, Wuhan University, Wuhan 430079, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li","family":"Luo","sequence":"additional","affiliation":[{"name":"Liaoning Bureau of Surveying, Mapping and Geoinformation Network Center, Shenyang 110034, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"issue":"9","key":"1","first-page":"1006","volume":"14","year":"2004","journal-title":"Progress in Natural Science"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/S0013-7952(99)00127-1"},{"issue":"1-2","key":"3","doi-asserted-by":"crossref","first-page":"33","DOI":"10.1016\/S0169-555X(01)00098-8","volume":"43","year":"2002","journal-title":"Geomorphology"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.5194\/nhess-7-185-2007"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.2478\/v10156-010-0022-3"},{"issue":"3","key":"6","first-page":"14","volume":"18","year":"1998","journal-title":"Crustal Deformation and Earthquake"},{"volume":"13","journal-title":"Highlights of Astronomy","year":"2004","key":"7"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1007\/s00190-009-0357-7"},{"year":"2016","key":"9"},{"issue":"4","key":"10","first-page":"331","volume":"27","year":"2002","journal-title":"Geomatics and Information Science of Wuhan University"},{"volume":"2, no. 5","year":"1968","series-title":"Geodesy","key":"11"},{"year":"2000","key":"12"},{"year":"2014","key":"13"},{"year":"2009","key":"14"},{"issue":"4","key":"15","doi-asserted-by":"crossref","first-page":"282","DOI":"10.1007\/BF03655099","volume":"11","year":"1986","journal-title":"Manuscripta Geodaetica"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1029\/90JB02003"},{"issue":"3","key":"17","first-page":"16","year":"2001","journal-title":"Journal of Geomatics"},{"issue":"1","key":"18","first-page":"4","volume":"23","year":"2003","journal-title":"Geomatic Science and Engineering"},{"issue":"2","key":"19","doi-asserted-by":"crossref","first-page":"36-1","DOI":"10.1029\/2002GL016279","volume":"30","year":"2003","journal-title":"Geophysical Research Letters"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1029\/2007JB004949"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.3969\/j.issn.0001-5733.2009.12.026"},{"first-page":"526","volume-title":"Quality control in geodetic networks","year":"1985","key":"22"},{"key":"23","doi-asserted-by":"publisher","DOI":"10.13203\/j.whugis20120019"},{"key":"24","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-246X.1990.tb06579.x"},{"year":"1996","key":"25"},{"volume":"164","year":"1971","series-title":"Deutsche Geod\u00e4tische Kommission","key":"26"}],"container-title":["Journal of Sensors"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2017\/9819214.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2017\/9819214.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2017\/9819214.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,6,25]],"date-time":"2025-06-25T20:56:11Z","timestamp":1750884971000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/js\/2017\/9819214\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017]]},"references-count":26,"alternative-id":["9819214","9819214"],"URL":"https:\/\/doi.org\/10.1155\/2017\/9819214","relation":{},"ISSN":["1687-725X","1687-7268"],"issn-type":[{"type":"print","value":"1687-725X"},{"type":"electronic","value":"1687-7268"}],"subject":[],"published":{"date-parts":[[2017]]}}}
