GeoICT laboratory always welcomes prospective students who are enthusiastically willing to pursue master or doctoral research projects in geospatial science and engineering!


Current Position Openings (Updated March 1, 2009)

We are always looking for self-motivated and talented post-graduate students who wish to work at the GeoICT lab. At present, the GeoICT lab is building research capacity with new graduate students in following fields:

  • Vision-based autonomous navigation of UGV (Unmanned Ground Vehicle) and UAV (Unmanned Aerial Vehicle) for risk-namagement applications.
  • Image rectification and sensor pose estimation of non-metric cameras for identification, re-identification of pedestrians and tracking people's movement in indoor or outdoor invironments.
  • 3D reconstruction of photo-reallistic building facade models.
  • Classification of building facade materilas using TLS or MLS.
  • Optimal SDSS (Spatial Decision Support System) for Green GIS applications.
  • Effective 3D redering and 3D sementic networking of large-scale cityscapes (in-door and outdoor) for LBS and ICT applications.
  • Sensor networking technology for indoor and outdoor survelliance.

2008-3) Graduate student research position - Spatiotemporal Power-line Risk Management Using GIS Technologies

Dr. Gunho Sohn is looking for self-motivated graduate student at MSc or PhD level in GIScience to develop a spatiotemporal risk management system for effectively managing Utilities, mainly transmission lines over the times using GIS technologies. The student will investigate a sophisticate risk process which affect physical transmission lines' safety by integrating 3D models of individual trees, transmission lines, towers and other man-made objects with spatial and temporal modeling of ambient temperature, wind, tree growth, land type, geological process, etc. An ultimate goal of this research aims to develop an innovative GIS system for effective management of power-line risks which requires advances in spatiotemporal decision making algorithms, geovisualization and GeoWeb technologies. An appropriate candidate is required to demonstrate strong academic interests in GIS and disaster management with an appropriate research background in one of following areas: applied mathematics, computer science/graphics, Geomatics Engineering, Environmental Science and Geography.


Expected Starting Date: ASAP or at the latest September 1, 2009. 

Project Sponsor: Ontario Accelerate Program, GeoDigital International Inc., OCE

Benefits: Students will closely work with GeoDigital International Inc. ( on the site for at least two months.

Please interested applicants send an email to Dr. Gunho Sohn ( with your resume and a short description of your research statement.
