Hi all, we will soon be getting into drone surveying and are currently planning on purchasing an Altusdrone. This comes with a Sony A5100 camera, and I am just wanting to get an impression of how good the camera will be for high accuracy (5-10mm, control placed by robotic total station) surveying compared to a Sony A7 II (Same 24MP, but larger sensor). The reason I was initially looking at the A7 II was the sensor size.
We can change the camera we want to come with the drone should we want too.
I was told that the sensor wont have too much impact, rather a quality lens will provide the best results.
The type of work at this stage will be road topo surveys, so narrow corridor work, likely flown at around 25m. I was also thinking a larger focal length, rather than a wide angle lens. My thinking there is less information on the sensor, therefore better detail in the corridor. Wider will be better for the larger surveys obviously.
I have had no experience with aerial surveying yet, and have been learning a lot form the forum.
Thanks in advance.
