@Juan R I'm late to the chat. We fly 6m VTOLs for LiDAR surveys, my friend is a surveyor and I help set platforms up and a little bit of flight testing when required. The real thing is you can't call it a survey if a surveyor has not signed it off, it has no legal standing. That's worldwide. So you do need the flight chops and survey knowledge.

You should have a good working knowledge of RTK and LiDAR all the reasons they fail in particular. Sadly the software to process all of this is silly expensive as well. So to round up my advice not knowing your entire situation, find a surveyor that needs drones and work with them. ( But perhaps you are a surveyor) Also the work fits perfectly into dull dangerous and dirty, it's dull! The flying is dull and the processing is dull! But it pays.

Solving a problem for someone is pretty much the best way to do things. I came from the world of flight to try and find an uncrewed way of lifting cameras, that was back in 2005, at the time there was no central news source so I started sUAS News to put stuff I found in one place for my friends. It grew out of that I am a pilot not a journalist! Being there in the early days of modern flight controllers meant along with my model aircraft knowledge I kept up with new ways of flying, multi rotors and eVTOLs spring to mind. That has led me to be able to help a friend setup large platforms that fly for six hours with LiDAR. Helping solve his problems. Off the shelf platforms are great these days. Creating actionable data from their sensors that solves problems is the hard bit.
