The formation and alteration of real property and rights, restrictions and responsibilities are important parts of land administration. Research on the distribution of publications in the three-dimensional (3D) cadastral domain has been in focus as a specialised part of real property research during the last decades. A number of literature surveys on research trends in the domain show a growing number of publications during the last decades. The number of publications have increased considerably within a range of topics, classified into legal, technical, registration and organisational categories of 3D property. The purpose of the research presented here is to contribute to these analyses of the number and thematic distribution of the 3D cadastral domain literature by analysing three aspects: 1) To add to the recent study by including 3D cadastre publications published during 2021 (Paasch and Paulsson, 2021a, 2021b); 2) To briefly analyse the classification of 3D cadastre research in technical programmes and proceedings of major conferences focussing, in total or in part, on 3D cadastre. 3) The results are used to contribute to the discussion regarding if the 3D cadastral domain is too diverse today to talk about a single 3D cadastral domain. An input to the discussion of what constitutes a domain is provided from an analysis of another land administration research topic that is often addressed in relation to 3D real property research; the international standard for land administration, the Land Administration Domain Model, LADM, ISO 19152. •Literature survey of 3D cadastre publications 2012–2021.•3D cadastre research is expanding into new territories.•Is it realistic still to talk about the 3D cadastral domain?
