However, most conventional selection methods are based solely on either a linear or an areal representation mode, often resulting in low selection accuracy and biased structural selection. In this paper we propose an improved hybrid method combining the linear and areal representation modes to increase the accuracy of road selection. The proposed method offers two primary advantages. First, it improves the stroke generation algorithm in a linear representation mode by using an ordinary least square (OLS) model to consider overall information for the roads to be connected. Second, by taking advantage of the areal representation mode, the proposed method partitions road networks and calculates road density based on weighted Voronoi diagrams. Roads were selected using stroke importance and a density threshold. Finally, experiments were conducted comparing the proposed technique with conventional single representation methods. Results demonstrate the increased stroke generation accuracy and improved road selection achieved by this method.<\/jats:p>","DOI":"10.3390\/ijgi6070196","type":"journal-article","created":{"date-parts":[[2017,7,3]],"date-time":"2017-07-03T10:27:31Z","timestamp":1499077651000},"page":"196","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["An Improved Hybrid Method for Enhanced Road Feature Selection in Map Generalization"],"prefix":"10.3390","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0093-0940","authenticated-orcid":false,"given":"Jianchen","family":"Zhang","sequence":"first","affiliation":[{"name":"College of Resources Environment and Tourism, Capital Normal University, Beijing 100048, China"},{"name":"3D Information Collection and Application Key Lab of Education Ministry, Capital Normal University, Beijing 100048, China"},{"name":"Beijing State key Laboratory Incubation Base of Urban Environmental Processes and Digital Simulation, Capital Normal University, Beijing 100048, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanhui","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Resources Environment and Tourism, Capital Normal University, Beijing 100048, China"},{"name":"3D Information Collection and Application Key Lab of Education Ministry, Capital Normal University, Beijing 100048, China"},{"name":"Beijing State key Laboratory Incubation Base of Urban Environmental Processes and Digital Simulation, Capital Normal University, Beijing 100048, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenji","family":"Zhao","sequence":"additional","affiliation":[{"name":"College of Resources Environment and Tourism, Capital Normal University, Beijing 100048, China"},{"name":"3D Information Collection and Application Key Lab of Education Ministry, Capital Normal University, Beijing 100048, China"},{"name":"Beijing State key Laboratory Incubation Base of Urban Environmental Processes and Digital Simulation, Capital Normal University, Beijing 100048, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,7,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"405","DOI":"10.1080\/15230406.2015.1104265","article-title":"How Many Samples are Needed?
