I got an interesting telephone call earlier today. The call was from a company who’s owning/running a ski resort in my home town See https://www.google.com/maps/place/67°06’09.7"N+20°37’39.7"Eemail@example.com,20.6263372,670m/data=!3m1!1e3!4m14!1m7!3m6!1s0x45d71c45e0c11709:0x2fcc4f970c0f9c2!2sDundret!3b1!8m2!3d67.0833333!4d20.5166668!3m5!1s0x0:0x0!7e2!8m2!3d67.1026921!4d20.6276887!5m1!1e4
Due to the Corona Hysteria everything has been closed since easter, and the man who contacted had a couple of questions to me regarding to get an Orthomap and a 3D of the slopes and use them in his marketing. He also wants to monitor the snow melting to get some knowledge on how the snow is melting and WHERE it melts first to be able to create a mountain bike trail asap to make some money.
The slopes are some 1,3 – 2,5 kilometers in length dropping some 300-400 meters during this distance. The highest begins at 823 meters above sea level. There are steep slopes an plateaus in a chaotic mixture as nature tends to be.
I can access the slopes in question by foot and create a capture and do the thing. But how does my P4P 2.0 act when I set the capturing height to 100 meters and begin my capture? Does the P4P keep the height when moving downhill (keeping the height by itself) or do I have to “cut” the slope in, say 4 – 5 captures and the use ALL images to do the Orto (and 3D).
Do I do the capture downhill or 90 degrees? Does it make any difference?
The key question is: Does my P4P Keep the height when moving downhill or does this take another type of drone/system? RTK?
Tried to do some searching on the net, but cannot find anything of interest. Surely this must have been done before, I think. Ifound a thread here from 2018, but this was f no help. I know there is a terrain awareness gizmo in the DJII app, but does this work using DD:s app for capturing? I’m using Android.
I’m thinking about to do this pro bono to help the poor company owner out in these miserable and difficult times.
Any hints, tips advices and tricks would be appreciated.
