The absence of evidence can lead to seemingly empty locations and isolated monuments. This, in turn, influences the cultural\u2013historical interpretation of archaeological sites. Here, we assess the potential of integrating thermal and magnetic remote sensing methods in the detection and mapping of buried archaeological structures. The area of interest in an alluvial plain in Tuva Republic makes the application of standard methods like optical remote sensing and field walking impractical, as natural vegetation features effectively hide anthropogenic structures. We combined drone-based aerial thermography and airborne and ground-based magnetometry to establish an approach to reliably identifying stone structures concealed within alluvial soils. The data integration led to the discovery of nine buried archaeological structures in proximity to an Early Iron Age royal tomb, shedding light on ritual land use continuity patterns.<\/jats:p>","DOI":"10.3390\/rs15204992","type":"journal-article","created":{"date-parts":[[2023,10,17]],"date-time":"2023-10-17T08:10:19Z","timestamp":1697530219000},"page":"4992","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Remotely Sensing the Invisible\u2014Thermal and Magnetic Survey Data Integration for Landscape Archaeology"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8190-7741","authenticated-orcid":false,"given":"Jegor K.","family":"Blochin","sequence":"first","affiliation":[{"name":"Institute for the History of Material Culture, Russian Academy of Sciences, Dvortsovaya Nabereznaya 18, 191186 St. Petersburg, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3837-2948","authenticated-orcid":false,"given":"Elena A.","family":"Pavlovskaia","sequence":"additional","affiliation":[{"name":"Institute of Earth Sciences, St. Petersburg State University, Universitetskaya Nabereznaya 7\/9, 199034 St. Petersburg, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8535-1173","authenticated-orcid":false,"given":"Timur R.","family":"Sadykov","sequence":"additional","affiliation":[{"name":"Institute for the History of Material Culture, Russian Academy of Sciences, Dvortsovaya Nabereznaya 18, 191186 St. Petersburg, Russia"}]},{"given":"Gino","family":"Caspari","sequence":"additional","affiliation":[{"name":"Department of Archaeology, University of Sydney, The Quadrangle A14, Sydney 2006, Australia"},{"name":"Institute of Archaeological Sciences, University of Bern, Mittelstrasse 43, 3012 Bern, Switzerland"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,17]]},"reference":[{"key":"ref_1","unstructured":"Ucko, P., Tringham, R., and Dimbleby, R.
