Concentration is, on the one hand, put on features, which originate in the measurement process themselves, and features derived by processing the point cloud. On the other hand, approaches for the processing of georeferenced point clouds are reviewed. This includes the data structures, but also spatial processing concepts. We suggest a categorization of features into levels that reflect the amount of processing. Point clouds are found across many disciplines, which is reflected in the versatility of the literature suggesting specific features.<\/jats:p>","DOI":"10.3390\/ijgi2041038","type":"journal-article","created":{"date-parts":[[2013,10,28]],"date-time":"2013-10-28T09:07:13Z","timestamp":1382951233000},"page":"1038-1065","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":66,"title":["Georeferenced Point Clouds: A Survey of Features and Point Cloud Management"],"prefix":"10.3390","volume":"2","author":[{"given":"Johannes","family":"Otepka","sequence":"first","affiliation":[{"name":"Department of Geodesy and Geoinformation, Vienna University of Technology, Gu\u00dfhaustra\u00dfe 27\u201329, Vienna 1040, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sajid","family":"Ghuffar","sequence":"additional","affiliation":[{"name":"Department of Geodesy and Geoinformation, Vienna University of Technology, Gu\u00dfhaustra\u00dfe 27\u201329, Vienna 1040, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christoph","family":"Waldhauser","sequence":"additional","affiliation":[{"name":"Institute for Statistics and Mathematics, WU Vienna University of Economics and Business, Welthandelsplatz 1, Vienna 1020, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ronald","family":"Hochreiter","sequence":"additional","affiliation":[{"name":"Institute for Statistics and Mathematics, WU Vienna University of Economics and Business, Welthandelsplatz 1, Vienna 1020, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2348-7929","authenticated-orcid":false,"given":"Norbert","family":"Pfeifer","sequence":"additional","affiliation":[{"name":"Department of Geodesy and Geoinformation, Vienna University of Technology, Gu\u00dfhaustra\u00dfe 27\u201329, Vienna 1040, Austria"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2013,10,25]]},"reference":[{"key":"ref_1","first-page":"40","article-title":"The Vienna laser scanning project","volume":"7","author":"Rieger","year":"2008","journal-title":"GEOconnex.
