What was this airplane doing?

I heard an airplane just diving at my house and found this on Flight Radar 24. I felt the shockwave.

There is a bunch of other odd ADSB data on the tail number that doesn’t make any sense. But I know this is one is correct.

Looking at the other track I’m seeing on FR24 don’t make any sense. It shows multiple different flights all withing the same time period.

I looked up the aircraft registration number and it’s to a company that offers a bunch of services including aerial mapping. Looking at their past flights it looks like that is what they were doing.

I kind of was thinking the same after seeing some of the other tracks. The altitude was unusually low.
