This Special Issue aims to capture the main trends in VGI research based on 16 original papers, and distinguishes between two main areas, i.e., those that deal with the characteristics of VGI and those focused on applications of VGI. The topic of quality assessment and assurance dominates the papers on VGI characteristics, whereas application-oriented work covers three main domains: human behavioral analysis, natural disasters, and land cover\/land use mapping. In this Special Issue, therefore, both the challenges and the potentials of VGI are addressed.<\/jats:p>","DOI":"10.3390\/ijgi6070202","type":"journal-article","created":{"date-parts":[[2017,7,4]],"date-time":"2017-07-04T10:31:57Z","timestamp":1499164317000},"page":"202","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Highlighting Current Trends in Volunteered Geographic Information"],"prefix":"10.3390","volume":"6","author":[{"given":"David","family":"Jonietz","sequence":"first","affiliation":[{"name":"Chair of Geoinformation Engineering, ETH Z\u00fcrich, Stefano-Franscini-Platz 5, 8093 Z\u00fcrich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vyron","family":"Antonio","sequence":"additional","affiliation":[{"name":"Hellenic Military Geographical Service, 4 Evelpidon, 11362 Athens, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7365-9995","authenticated-orcid":false,"given":"Linda","family":"See","sequence":"additional","affiliation":[{"name":"International Institute for Applied Systems Analysis (IIASA), Schlossplatz 1, A-2361 Laxenburg, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2665-7065","authenticated-orcid":false,"given":"Alexander","family":"Zipf","sequence":"additional","affiliation":[{"name":"GIScience Research Group, Institute of Geography, University of Heidelberg, 69120 Heidelberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,7,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"211","DOI":"10.1007\/s10708-007-9111-y","article-title":"Citizens as sensors: The world of volunteered geography","volume":"69","author":"Goodchild","year":"2007","journal-title":"GeoJournal"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"See, L., Mooney, P., Foody, G., Bastin, L., Comber, A., Estima, J., Fritz, S., Kerle, N., Jiang, B., and Laakso, M.
