We are company providing Drone Data Services and have experience of mapping large areas using drones. We have been building High Performance Composite UAVs for mapping Application. We have built drones that flies for two hours and carries about 1kg payload and have covered upto 12 sq. km. (at 5cm resolution) in a single flight.
We are not working on a similar high performance but very affordable platform which we could bring to you. Here you can help us understand what would your ideal platform that you would like to use for mapping. Attached here is a survey link which would help us understand your response.
Please take our just 5 minutes to answer the simple question and allow us to narrow down our design constraints and we will be back with an awesome product very soon. If you would like to know more about our past work and drones we built, please feel free to drop me a line at firstname.lastname@example.org
