 Three-dimensional models of urban environments are useful in a variety
of applications. They are typically represented either as Digital
Surface Models (DSM) or triangular 3D meshes. A standard technique for
obtaining the geometry of a large-scale city area in an automated or
semi-automated way is to apply stereo vision techniques on aerial or
satellite imagery. DSMs and 3D models can also be obtained from
Synthetic Aperture Radar (SAR) or from airborne laser scans Recently,
ground-based data acquisition systems have been developed, which are
capable of scanning the geometry of building facades as seen from the
street level..
Our Expertise :
3D visualization models have a variety of applications in geography and
urban studies: site location analysis, emergency facilities planning,
design review, marketing, etc. While they are generally used to simply
visualize the built environment, there are early signs of them being
used as 3D interfaces to more sophisticated simulation models.
Areas of usage include :
Gaming companies
RF Planning Companies
Real Estate
