Hello,
I have an industrial plant that covers approximately 0,25km2 (0.1mi2).
My plant have 2 furnaces/towers 200’ height.
I want to create the best 3d possible with a Mavic 3E drone. I’m new to this but willing to learn!
I plan to create multiple flight. (orthomosaic, ortho with gimble at an angle; 45deg?, and facade flight)
I would like to get some tips for my flight planning. (distance, height, gamble angle, number of flight, technique, etc).
I will be using pix4dmatic and or pix4dmapper for doing the 3D.
I have an RS3 base station and going to have a certain number of GCP (to determine).
I’m also considering doing ground scan for scanning equipement with another device. (cellphone and pix4dcapturepro? not sure how to reference rtk/ppk)
In summary, I would like to have your advice on the process and techniques to speed up my learning curve! 
Thanks!
JP
