Google’s Street View Cars Are Now Tracking Air Pollution

Almost half of the world’s population, rising to 80 percent of people living in cities, breathe air that is unsafe for humans.
But it’s hard to tell, if you live in a city, where the most dangerous areas are. TechRadar has reported that for the last year, Google has been driving its Street View cars around Oakland, California, with air pollution sensors on the roofs. And now the company has released its first map of the results.
In partnership with the University of Texas, the search company mapped 78 square miles of Oakland over an entire year, collecting readings every 30 metres or so. That’s an extremely high level of detail – substantially greater than is possible with traditional static air quality monitors. Most large urban areas have one air quality monitor for every 100-200 square miles.
