What are the possibilities of open data?

Many people refer to the time we live in as the Information Age, and I think to make best use of the digital data that we possess, the data should be open. The open data initiative advocates that certain data should be available for everyone to use without encumbrance. It should also be machine readable so that software can be built to take advantage of the data.

There are already many institutions providing open data, for example, several Canadian cities are providing data for people to use here:

The data being opened include geographic data and 3D buildings data in the city, as well as information on services such as phone numbers.

What types of technologies can be built from the use of that open data?
