IT ISN'T ALL ABOUT PHOTOGRAPHY
There is a lot of uncertainty in the US UAV market due to lack of data. We do not have accurate sales data, number of hours flown, number of incidents, or even a good definition of what a UAV incident is. However, there is one really good UAV related dataset: Authorizations Granted Via Section 333 Exemptions. This is the FAA's list of exemptions granted to allow commercial UAV operations.
