The buildings were classified into nine distinct types and initially extracted from a satellite image of the year 2015. Secondly, changes were identified based on a visual interpretation of an image of the year 2017, so that new buildings, demolished buildings and building upgrades can be quantitatively analyzed. The data was aggregated by administrative wards and a hexagonal grid with a diameter of 250 m to protect personal rights and to avoid the misuse of a single building\u2019s information. The dataset shows an increase of 19,391 buildings between October 2015 and August 2017, with a variety of interesting spatial patterns. The center of the city is mostly dominated by building changes and upgrades, while most of the new buildings were constructed within a distance of five to six kilometers from the city center.<\/jats:p>","DOI":"10.3390\/data5020042","type":"journal-article","created":{"date-parts":[[2020,4,23]],"date-time":"2020-04-23T10:46:22Z","timestamp":1587638782000},"page":"42","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Changes in the Building Stock of Da Nang between 2015 and 2017"],"prefix":"10.3390","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8630-1389","authenticated-orcid":false,"given":"Andreas","family":"Braun","sequence":"first","affiliation":[{"name":"Institute of Geography, University of T\u00fcbingen, 72070 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gebhard","family":"Warth","sequence":"additional","affiliation":[{"name":"Institute of Geography, University of T\u00fcbingen, 72070 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6181-0187","authenticated-orcid":false,"given":"Felix","family":"Bachofer","sequence":"additional","affiliation":[{"name":"German Aerospace Center (DLR), Earth Observation Center (EOC), 82334 Wessling, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tram Thi","family":"Quynh Bui","sequence":"additional","affiliation":[{"name":"Da Nang Institute for Socio-Economic Development (DISED), Da Nang City 550000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9281-8437","authenticated-orcid":false,"given":"Hao","family":"Tran","sequence":"additional","affiliation":[{"name":"Da Nang Urban Planning Institute (UPI), Da Nang City 550000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Volker","family":"Hochschild","sequence":"additional","affiliation":[{"name":"Institute of Geography, University of T\u00fcbingen, 72070 T\u00fcbingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"267","DOI":"10.1007\/s11769-003-0029-0","article-title":"Application of remote sensing technology to population estimation","volume":"13","author":"Zhang","year":"2003","journal-title":"Chin.
