New to GeoWeb 2009 is the Academic Track. On Wednesday (July 29) and Thursday (July 30) this special program will be dedicated to the presentation of research results in all scientific fields related to 3D Cityscapes and contribute to the state of the art in support of city modeling including in particular 3D structure design, semantic modeling, model acquisition, visualization, and analysis.

The Academic Track of the GeoWeb 2009 conference is co-organized by the three Working Groups III/4, IV/8, and IV/5 of the International Society for Photogrammetry and Remote Sensing (ISPRS), Galdos Systems Inc., and Simon Fraser University.

The main theme of GeoWeb 2009 is 3D Cityscapes, riding on the growing importance and technological and research advances in 3D modeling, data acquisition, data processing, and visualization. Relevant current research on 3D Cityscapes shall be presented and discussed from, among others, the fields of geoinformation science, computer graphics, architecture and civil engineering, photogrammetry and remote sensing, computer vision, computer games, and simulation.

To register for the Academic Track please visit the Registration Page.

All of the papers submitted to the Academic track have been peer reviewed. Twelve papers have been accepted and will be published in the conference proceedings; 8 additional papers have been accepted for poster presentation. The schedule is as follows:

Day 1 (Wednesday, July 29)

Timing: 9:30am - 10:15am
Opening Session: Thomas H. Kolbe & Sisi Zlatanova

Digital cityscapes are investigated in different research domains like geoinformation sciences and photogrammetry (GIS), computer graphics and computer vision, and computer aided architectural design (BIM). In the opening session the different origins, their corresponding modeling approaches and their interrelationships will be reviewed, being a key motivation for the Academic Track.

Furthermore, the use of virtual city and landscape models for disaster management will be highlighted and an introduction to the corresponding ISPRS working groups will be given.

Timing: 10:30am - 12:00pm

Day 2 (Thursday, July 30)

Timing: 9:30am - 10:15am
Invited Speaker: Dr. Baoquan Chen

Digital Earth platforms such as Google Earth and Microsoft Virtual Earth have seen explosive growth in applications by governments,industry, and end users. This has thus provided impetus for more efficient and capable tools to push 3D representation and simulation of urban environments to a finer level than it is today. In this talk I introduce our effort on acquiring, modeling, and visualizing large and detailed urban environments, facilitating generation of a “live” digital city environment.  Learn more about Dr. Baoquan Chen on the Invited Speaker page.
