The 3D GeoInfo Journey from 2006 to 2022: A Reflection

This paper describes research on 3D GIS and the related studies undertaken by the community that were published and presented at the 3D GeoInfo conferences from 2006 to 2022: the first conference was organized in Kuala Lumpur and the 17th conference in Sydney. Several earlier works (published prior to 2006) are also part of the compilation, forming a basis of the 3D GIS research literature and part of the introduction of this paper. Almost all events in the series are described, with the exception of the Wuhan version. The descriptions are categorized into two decades, and the reflections of the 3D GIS research, and development (R-&-D) are highlighted towards the end of the paper.
