Planet Labs captures 1.2 million images daily!, page-7

Agricultural doesn't require the same resolution fly a fair bit higher I imagine - but it does require different spectrums. Then again, the multispectral cameras might not have the same mpix counts.

I imagine Nearmap already have their hands full and the planes are probably pretty busy - but a multispectral capture might have a business case.

Large chunk of ground to cover mind you. But if you were to value add with simultaneous LIDAR or other sensors, it might make sense.
