This paper proposes a multi-level population spatialization method on the different administrative levels with the support of China\u2019s first national geoinformation survey, and then considers several approaches to verify the results of the multi-level method. This paper aims to establish a multi-level population spatialization method that is suitable for the administrative division of districts and streets. It is assumed that the same residential house has the same population density on the district level. Based on this assumption, the least squares regression model is used to obtain the optimized prediction model and accurate population space prediction results by dynamically segmenting and aggregating house categories.In addition, it is assumed that the distribution of the population is relatively regular in communities that are spatially close to each other, and that the population densities on the street level are similar, so the average population density is assessed by optimizing the community and surrounding residential houses on the street level. Finally, the scientificalness and rationality of the proposed method is proved by spatial autocorrelation analysis, overlay analysis, cross-validation analysis and accuracy assessment methods.<\/jats:p>","DOI":"10.3390\/s18082558","type":"journal-article","created":{"date-parts":[[2018,8,7]],"date-time":"2018-08-07T03:44:18Z","timestamp":1533613458000},"page":"2558","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Methods of Population Spatialization Based on the Classification Information of Buildings from China\u2019s First National Geoinformation Survey in Urban Area: A Case Study of Wuchang District, Wuhan City, China"],"prefix":"10.3390","volume":"18","author":[{"given":"Linze","family":"Li","sequence":"first","affiliation":[{"name":"School of Remote Sensing and Information Engineering, Wuhan University, Wuhan 430072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiansong","family":"Li","sequence":"additional","affiliation":[{"name":"School of Remote Sensing and Information Engineering, Wuhan University, Wuhan 430072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zilong","family":"Jiang","sequence":"additional","affiliation":[{"name":"School of Remote Sensing and Information Engineering, Wuhan University, Wuhan 430072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lingli","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Remote Sensing and Information Engineering, Wuhan University, Wuhan 430072, China"},{"name":"State Key Laboratory of Information Engineering in Surveying, Mapping &amp; Remote Sensing, Wuhan University, Wuhan 430072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1581-634X","authenticated-orcid":false,"given":"Pengcheng","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Remote Sensing and Information Engineering, Wuhan University, Wuhan 430072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,8,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1128","DOI":"10.3390\/s90201128","article-title":"An updating system for the gridded population database of china based on remote sensing, GIS and spatial database technologies","volume":"9","author":"Yang","year":"2009","journal-title":"Sensors"},{"key":"ref_2","first-page":"2109","article-title":"The corresponding relationships between the demographic transition, urbanization process, and industrial development of China","volume":"29","author":"Chen","year":"2010","journal-title":"Geogr.
