I always collect more points than the aerial mapper specified. I may share some but will use others as an independent check on the mapping. With RTK, it is very easy to collect additional points. Discovering problems early gives more time to resolve and hopefully still meet deadlines. Once the mapping is delivered, additional field verification is performed before the mapping is accepted.

Got to demo a Microdrones MD4-1000DG this week; 42.4MP Sony Rx1RII camera flying at 164' AGL; supposedly producing 0.2" GSD. Haven't processed any of it yet.

That would just about do it.

The new DJI M200 with their Z4S would be a useful tool, but not 42megapixel useful.

I imagine that much data will take a powerful machine quite a while process. What is your office setup?

Dual Zeon ten core processors with 64GB RAM, dual 500GB SSD, 8GB NVIDIA card, and an 8TB Seagate backup drive.

Sometimes it doesn't matter how much horsepower the PC has, the software doesn't seem to take advantage of it. Some are better than others.
