Apte Research Group: Mapping air pollution with Google Street View cars

Apte Research Group:
Mapping air pollution with Google Street View cars
. “We used two specially equipped Google Street View cars to repeatedly map gaseous and particulate air pollution, block-by-block, in Oakland, California. By using a year of repeated measurements, our algorithms were able to map pollution at 30 meter scales – an unprecedented resolution for a measurement dataset. We find that air quality can persistently vary even within individual city blocks. We determined that the data requirements for making stable, high-resolution pollution maps are surprisingly modest. This straightforward measurement technique could be scaled up to other cities around the world.”
