Tomorrow’s <strong>Digital</strong> <strong>City</strong> Models<br />
� Precise model of a city<br />
� Representation with varying degrees of<br />
context and reality<br />
� Visualization of all modes of operation<br />
within a city<br />
� See projects in their proper setting and<br />
experience them from any point of view or<br />
point in time<br />
