The First International Workshop on 3D Geoinformation took place on 7 & 8 August, 2006 at The Legend Hotel, Kuala Lumpur. The event was officiated by Y. Bhg. Datuk Professor Ir Dr Mohd Zulkifli b. Tan Sri Mohd Ghazali, Vice Chancellor, Universiti Teknologi Malaysia. It was hosted by the Department of Geoinformatics, Faculty of Geoinformation Science and Engineering in collaboration with the International Society of Photogrammetry and Remote Sensing (ISPRS), Delft University of Technology, the Netherlands, Stuttgart University of Applied Sciences, Germany, Land Surveyors Board of Peninsular Malaysia, and Department of Survey and Mapping Malaysia (JUPEM). The event was also supported by Autodesk (platinum sponsor). A total of 58 technical papers and 6 posters were presented at the workshop. The presentations were divided into 12 parallel sessions that represent major aspects in 3D GIS, namely, 3D spatial data acquisition – LIDAR and digital photogrammetry; 3D spatial data modeling and representation (I) and (II); 3D GIS frameworks (I) and (II); 3D object reconstruction; 3D object reconstruction and mobile mapping; 3D city modeling; 3D mapping, cadastre, and utility; 3D visualization (I) and (II); and 3D terrain modeling and orthophoto generation. A total of 250 participants registered for the event including 70 overseas participants from 25 countries (USA, Canada, The Netherlands, Germany, U.K., Denmark, France, Sweden, Italy, Slovenia, Russia, Australia, Brazil, China, Iran, Jordan, Nigeria, Oman, UAE, India, Indonesia, Syria, Singapore, South Korea, Taiwan).
In the exhibition area, a total of 17 major exhibitors (local and international) in GIS, remote sensing, photogrammetry, GPS and surveying displayed their products and services. The Department of Survey and Mapping Malaysia (JUPEM) and the Malaysian Centre for Remote Sensing also participated.
The 12 parallel sessions were focusing on 3D aspect of geoinfomation ranging from spatial data collection to visualization. Various problems, issues, and challenges were addressed by speakers and audience. Keynote 1 was presented by Prof Dr Sisi Zlatanova (from TU Delft, the Netherlands). She highlighted the issue of creating spatial databasing for 3D objects and several experiments were described. The other keynote paper (Keynote 2) by the Director General of Survey and Mapping Malaysia was presented by his Deputy. The paper revealed the new initiatives and vision of the JUPEM on the aspect of 3D geoinformation products and services. Keynote 3 was presented by Professor Dr Volker Coors from HfT Stuttgart, Germany. He described the new 3D web services highlighting the emerging trend – smart urban environment. Keynote 4 was presented by Dr Geoff Zeiss from Autodesk, which dealt with 3D spatial data standard and initiatives from Open GIS Consortium (OGC).
The technical papers have been published by Springer-Verlag based in Heidelberg, Germany as Lecture Notes in Geoinformation and Cartography series with the title – ‘Innovations in 3D Geo Information Systems’. The book is edited by Alias Abdul Rahman (UTM, Malaysia), Sisi Zlatanova (TU Delft, the Netherlands), and Volker Coors (HfT Stuttgart, Germany).
The workshop clearly demonstrated how 3D geoinformation was increasingly becoming a pre-requisite tool for many users who are embarking on advanced GIS applications. A lot of efforts are needed from GIS scientists and researchers in realizing the 3D GIS software and solutions.
