"Many thanks Cedric just a final point before I move to the direct email, if the ground is a mixture of bare ground, glass of different heights, crops and some trees (typical of Africa arable land) the would the accuracy be OK?
We will go through the…"
"Jeff, We will certainly upload the images along .tlog.
Re geotagging are you looking to get a camera that automatically does that? It seems quite straightforward to me.
Well done to your E384. We were quite nervous at first but our trust grew…"
The area we surveyed was very remote in Africa. Google earth image was very poor.
Impressive accuracies you got there. Have you done a comparison between survey by total station and by drone for engineering design.
Can you say that in…"
"Thank you for your advice. We think photogrammetry is a specialist skill that is best left to professionals. The flying was fun but we will look to fight people to work with on multiple projects. Best. Quan"
"Sure Gary - One of the reasons why we want to outsource the flying. It was fun but apart from the licensing issue, we would rather focus on the actionable insights - we are ag developer and manager, not drone surveyor.
Thanks again for your advice…"
The first flight was at 180m and second at 120m AGL. They were entirely autonomous so I am not sure how the change in AGL affected the accuracy. Anyway for irrigation planning and we need accurate in the cm. It is actually not difficult for…"
"Sounds great Pravin. For UAV surveys the key outputs we need for irrigation planning and design are:
- contour map with x y z at scale of 1:500
As we are designing, developing and managing agriculture projects in Africa we would like to…"
