Met Office: Storm Tracker
The UK Met Office has created a new Google Maps based application to monitor and forecast tropical cyclones around the world.
The application allows you to view worldwide cloud conditions and the locations of current cyclones. If you select a cyclone on the map you can view the cyclone's observed track and wind speeds recorded along the track.
As well as viewing current tropical storm conditions it is also possible to view historical storm information. For example you can view the track of the 2005 Hurricane Katrina.
MyBlockNYC is a Google Maps based application that allows users to upload and explore videos documenting the life and culture of New York City.

As well as exploring the videos by location you can filter the results by category, by time of day and season, and by the age and sex of the film-maker.
