In this paper, we addressed the problem of cross-section thickness optimization regarding DBH estimation bias and accuracy. DBH of 121 European beeches (Fagus sylvatica L.) and 43 Sessile oaks (Quercus petraea (Matt.) Liebl.) was estimated from cross-sections with thicknesses ranging from 1 to 100 cm. The impact of cross-section thickness on the bias, standard error, and accuracy of DBH estimation was statistically significant. However, the biases, standard errors, and accuracies of DBH estimation were not significantly different among 1\u201310-cm cross-sections, except for oak DBH estimation accuracy from an 8-cm cross-section. DBH estimations from 10\u2013100-cm cross-sections were considerably different. These results provide insight to the influence of cross-section thickness on DBH estimation by circle-fitting methods, which is beneficial for point cloud data acquisition planning and processing. The optimal setting of cross-section thickness facilitates point cloud processing and DBH estimation by circle-fitting algorithms.<\/jats:p>","DOI":"10.3390\/ijgi9090495","type":"journal-article","created":{"date-parts":[[2020,8,21]],"date-time":"2020-08-21T09:21:51Z","timestamp":1598001711000},"page":"495","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["The Influence of Cross-Section Thickness on Diameter at Breast Height Estimation from Point Cloud"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2956-944X","authenticated-orcid":false,"given":"Milan","family":"Kore\u0148","sequence":"first","affiliation":[{"name":"Department of Forest Resources Planning and Informatics, Faculty of Forestry, Technical University in Zvolen, T.
