This article reports on experiments with a hybrid spatial disaggregation technique that combines the ideas of dasymetric mapping and pycnophylactic interpolation, using modern machine learning methods to combine different types of ancillary variables, in order to disaggregate historical census data into a 200 m resolution grid. We specifically report on experiments related to the disaggregation of historical population counts from three different national censuses which took place around 1900, respectively in Great Britain, Belgium, and the Netherlands. The obtained results indicate that the proposed method is indeed highly accurate, outperforming simpler disaggregation schemes based on mass-preserving areal weighting or pycnophylactic interpolation. The best results were obtained using modern regression methods (i.e., gradient tree boosting or convolutional neural networks, depending on the case study), which previously have only seldom been used for spatial disaggregation.<\/jats:p>","DOI":"10.3390\/ijgi8080327","type":"journal-article","created":{"date-parts":[[2019,7,26]],"date-time":"2019-07-26T11:55:22Z","timestamp":1564142122000},"page":"327","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Spatial Disaggregation of Historical Census Data Leveraging Multiple Sources of Ancillary Information"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4491-3744","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Monteiro","sequence":"first","affiliation":[{"name":"IST\/INESC-ID, Universidade de Lisboa, 1649-004 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3856-2936","authenticated-orcid":false,"given":"Bruno","family":"Martins","sequence":"additional","affiliation":[{"name":"IST\/INESC-ID, Universidade de Lisboa, 1649-004 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9904-0288","authenticated-orcid":false,"given":"Patricia","family":"Murrieta-Flores","sequence":"additional","affiliation":[{"name":"Digital Humanities Hub, Lancaster University, Lancaster LA1 4YW, UK"}]},{"given":"Jo\u00e3o M.","family":"Pires","sequence":"additional","affiliation":[{"name":"FCT\/NOVA LINCS, Universidade NOVA de Lisboa, 1099-085 Lisboa, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2019,7,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Lloyd, C.D.
