The imagery has been orthorectified for terrain corrected geographic precision. Additionally, the imagery has been contrast stretched using a custom stretch and processed into a Tiled Map Service (TMS) for performance.

I added it to the imagery resources of JOSM. I started using the imagery to find bus stops with bays. Those are easily recognizable on this imagery.
