Topographic parameters based on light detection and ranging (LiDAR)-based high-resolution digital elevation model (DEM) provide obvious correspondence with the expected form of landscape features. The information on slope, curvature, and openness can help identify the location of landscape features. This study applied the automatic landscape line detection to extract historic vegetable garden wall lines from a LiDAR-derived DEM. The three rapid processes used in this study included the derivation of topographic parameters, line extraction, and aggregation. The rules were extracted from a decision tree to check the line detection from multiple topographic parameters. Results show that wall line detection with multiple topographic parameter images is an alternative means of obtaining essential historic wall feature information. Multiple topographic parameters are highly related to low wall feature identification. Furthermore, the accuracy of wall feature detection is 74% compared with manual interpretation. Thus, this study provides rapid wall detection systems with multiple topographic parameters for further historic landscape management.<\/jats:p>","DOI":"10.3390\/ijgi6110346","type":"journal-article","created":{"date-parts":[[2017,11,7]],"date-time":"2017-11-07T11:46:01Z","timestamp":1510055161000},"page":"346","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Historic Low Wall Detection via Topographic Parameter Images Derived from Fine-Resolution DEM"],"prefix":"10.3390","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8062-462X","authenticated-orcid":false,"given":"Hone-Jay","family":"Chu","sequence":"first","affiliation":[{"name":"Department of Geomatics, National Cheng Kung University, Tainan 701, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Min-Lang","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Geomatics, National Cheng Kung University, Tainan 701, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu-Ching","family":"Tain","sequence":"additional","affiliation":[{"name":"Department of Geomatics, National Cheng Kung University, Tainan 701, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mon-Shieh","family":"Yang","sequence":"additional","affiliation":[{"name":"Institute of Geography, Heidelberg University, Heidelberg 69117, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5849-1461","authenticated-orcid":false,"given":"Bernhard","family":"H\u00f6fle","sequence":"additional","affiliation":[{"name":"Institute of Geography, Heidelberg University, Heidelberg 69117, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,11,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"83","DOI":"10.1016\/j.jqsrt.2003.12.030","article-title":"Photogrammetry and remote sensing in archeology","volume":"88","author":"Kucukkaya","year":"2004","journal-title":"J.
