Courses / Descriptions395/495 - Geospatial Vision and Visualization
Quarter OfferedWinter : Tu 6-9 ; Chen, Xin
COURSE DESCRIPTION: Geospatial information has become ubiquitous in everyday life, as evidenced by on-line mapping services such as Microsoft Virtual Earth/Bing Map, the recent addition of "place" features on social network websites such as Facebook, and free navigation on Nokia smart phones. Behind the scenes is digital map content engineering that enables all types of location-based services. Course material will be drawn from the instructor's research experience at NOKIA Location and Commerce (formerly NAVTEQ), the Chicago-based leading global provider of digital map, traffic and location data. This course will provide comprehensive treatment of computer vision, image processing and visualization techniques in the context of digital mapping, global positioning and sensing, next generation map making, and three-dimensional map content creations. Real world problems and data and on-site industry visits will comprise part of the course curriculum.
- The course satisfies the interfaces breadth and depth requirements.
