Maps of the world around us are used daily for many purposes such as navigation
or location-based services. However, our experience with maps is usually limited
to a 2D top-down projection. Using a 3D map instead have some advantages, such as
easier navigation and orientation, more realistic modeling and simulation of natural
phenomena such as water flow or line-of-sight analysis, and better understanding of
the elevation differences.
In this talk, we will present a few methods that can provide us with better 3D maps:
- Augmentation of 2D road interchanges to 3D using GPS traces recorded while driving.
- Refinement and amelioration of digital terrain models (DTMs) using GPS traces
recorded in the area.
- Estimating buildings' elevations using the accelerometers and magnetometers in
We demonstrate these methods based on the map of the OpenStreetMap project, with
the results visualized in 3D (http://osm3d.cs.technion.ac.il/).
This talk summarizes the M.Sc. research of the speaker under the supervision of Prof. Gershon Elber.
