Three-dimensional (3D) geoinformation has been the subject within geoinformation (GIS) community and other related professionals since early 90's. Recently the subject is getting more attention when users demand better information of the phenomena and of the surrounding objects. A lot of efforts and time have been invested for this kind of 3D geoinformation solution but operationally such system is still hardly available in mass market. For this reason the Department of Geoinformatics, Faculty of Geoinformation Science and Engineering, Universiti Teknologi Malaysia took the initiative to organize the first International Workshop on 3D Geoinformation held in South East Asia, held on 7-8 August, 2006, Kuala Lumpur, Malaysia. The workshop has covered fundamental aspects of 3D geoinformation as well as 3D data collection (LIDAR and other means), 3D spatial data modeling, 3D databases, 3D spatial analysis, 3D visualization, and some applications in 3D geoinformation. This workshop has gathered researchers, system developers, practitioners, and end users from 21 countries, coming from 5 different continents. They have the great opportunity to discuss new research development, ideas, theories, and possible applications in this very specialized but fast emerging field.
