Streaming photographs from another site onto a Google Map is just sooo 2008 - or at least it will be once users have seen Casper.
This mashup from a Dutch firm called Frontier takes a feed from air traffic control in Holland and plots live aircraft movements around Schiphol Airport in Amsterdam.
Wondering how they get the data? Aircraft are tracked using a ADS-B receiver located on the roof of the Frontier office in Amsterdam!
A side widget on the site include various pieces of information on each aircaft including current height, origin, destination, airline, type (including dimensions and engine details) and a photograph.
Here is the embedded version:
Casper isn't Frontier's only product using such technology and mashups - the company has aircraft noise widgets for environmental organisations and traffic management software for ground-based firms or airlines.
Raymond Michiels from Frontier says:

"We are examining ways to expand. We may sell Casper to airports or other aviation authorities; we may also go with an (ad) sponsored version.
"Right now we are weighing the pros and cons (initial investment versus possible income)."
