As a consequence, the choice between these visualization techniques is still mostly supported by empirical knowledge. Some attempts have been made to compare these techniques, but there is still a lack of analytical data. This work proposes a new method, based on gradient modelling and spatial statistics, to analytically assess the efficacy of these visualization techniques. A selected panel of outstanding visualization techniques was assessed first by a classic non-analytical approach, and secondly by the proposed new analytical approach. The comparison of results showed that the latter provided more detailed and objective data, not always consistent with previous empirical knowledge. These data allowed us to characterize with precision the terrain for which each visualization technique performs best. A combination of visualization techniques based on DEM manipulation (Slope and Local Relief Model) appeared to be the best choice for normal terrain morphometry, occasionally supported by illumination techniques such as Sky-View Factor or Negative Openness as a function of terrain characteristics.<\/jats:p>","DOI":"10.3390\/rs9020120","type":"journal-article","created":{"date-parts":[[2017,2,10]],"date-time":"2017-02-10T05:27:09Z","timestamp":1486704429000},"page":"120","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":37,"title":["The Highest Gradient Model: A New Method for Analytical Assessment of the Efficiency of LiDAR-Derived Visualization Techniques for Landform Detection and Mapping"],"prefix":"10.3390","volume":"9","author":[{"given":"Alfredo","family":"Mayoral","sequence":"first","affiliation":[{"name":"Universit\u00e9 Clermont Auvergne, Universit\u00e9 Blaise Pascal, GEOLAB, BP 10448, F-63000 CLERMONT-FERRAND, France"},{"name":"CNRS, UMR 6042, GEOLAB, F-63057 CLERMONT-FERRAND, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean-Pierre","family":"Toumazet","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Clermont Auvergne, Universit\u00e9 Blaise Pascal, GEOLAB, BP 10448, F-63000 CLERMONT-FERRAND, France"},{"name":"CNRS, UMR 6042, GEOLAB, F-63057 CLERMONT-FERRAND, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fran\u00e7ois-Xavier","family":"Simon","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Clermont Auvergne, Universit\u00e9 Blaise Pascal, Maison des Sciences de l\u2019Homme, BP 10448, F-63000 CLERMONT-FERRAND, France"},{"name":"CNRS, USR 3550, MSH, F-63057 Clermont-Ferrand, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Franck","family":"Vautier","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Clermont Auvergne, Universit\u00e9 Blaise Pascal, Maison des Sciences de l\u2019Homme, BP 10448, F-63000 CLERMONT-FERRAND, France"},{"name":"CNRS, USR 3550, MSH, F-63057 Clermont-Ferrand, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7675-2741","authenticated-orcid":false,"given":"Jean-Luc","family":"Peiry","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Clermont Auvergne, Universit\u00e9 Blaise Pascal, GEOLAB, BP 10448, F-63000 CLERMONT-FERRAND, France"},{"name":"CNRS, UMR 6042, GEOLAB, F-63057 CLERMONT-FERRAND, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2017,2,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"155","DOI":"10.1088\/1742-2132\/7\/2\/S01","article-title":"On the LiDAR contribution for the archaeological and geomorphological study of a deserted medieval village in Southern Italy","volume":"7","author":"Lasaponara","year":"2010","journal-title":"J.
