When the situation with broken contour lines is severe or the terrain is more complex, incorrect and missing connections are most likely to occur using traditional methods. In this paper, a reconstruction method for broken contour lines based on similar and completely closed contours is proposed. First, node densification is conducted on broken contour lines to improve the identification accuracy of the reference line. Second, the discrete Fr\u00e9chet distance is used to select a reference line and perform reconstruction. Finally, the actual data of Yunnan Province are utilized for verification. The results show that the method proposed in this paper can achieve better reconstruction of broken contour lines, especially for severe broken contour situations or complex terrains; the reconstruction accuracy is significantly improved over that of the traditional method, indicating good feasibility.<\/jats:p>","DOI":"10.3390\/ijgi8010008","type":"journal-article","created":{"date-parts":[[2018,12,26]],"date-time":"2018-12-26T11:31:21Z","timestamp":1545823881000},"page":"8","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["A Reconstruction Method for Broken Contour Lines Based on Similar Contours"],"prefix":"10.3390","volume":"8","author":[{"given":"Chengming","family":"Li","sequence":"first","affiliation":[{"name":"Chinese Academy of Surveying and Mapping, 28 Lianhuachi West Road, Beijing 100830, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaoli","family":"Liu","sequence":"additional","affiliation":[{"name":"Chinese Academy of Surveying and Mapping, 28 Lianhuachi West Road, Beijing 100830, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Wu","sequence":"additional","affiliation":[{"name":"College of Geomatics, Shandong University of Science and Technology, 579 Qianwangang Road, Qingdao 266590, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhiwei","family":"Hao","sequence":"additional","affiliation":[{"name":"Chinese Academy of Surveying and Mapping, 28 Lianhuachi West Road, Beijing 100830, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,12,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"642","DOI":"10.1016\/j.jvcir.2012.02.005","article-title":"A new approach to the reconstruction of contour lines extracted from topographic maps","volume":"23","author":"Samet","year":"2012","journal-title":"J.
