Hi. THis past weekend I was prompted to calibrate the IMU by my P4 Adv, but was doing a remote mission on a hillside with ~ 3 ft of snow--So it was hard to find a level spot to launch from/calibrate at. The Calibration stopped part way through, and even after shutting everything down, and...

It sounds to me like the problem is that the coordinates are in deg in the original software but are being 'read' as in UTM Zone 0 in the second software, and thus placed near 0,0, or that only the last 3 digits of UTM coordinates are being read by the second software which is expecting...

There is a way to install other controller apps on the + controller. At least, I did it 2 years ago with mine, and with Litchi (not Pix4D). YOu have to go through the Amazon store, but I followed info. I found on Youtube and it worked fine. I also was never confident that I had fully shut...

You can actually install LItchi on the + model controller with the built-in/hard wired screen, though in a bit of a roundabout way, I have used a 3rd party software ($99) called DJIFLightPlanner which does allow you to plan grid missions, then export them as a .csv which Litchi can then run as a...

I think the new rules say you have to do it with your drone held down at knee level; penalty stroke if held out at arm's length...

I think you would have to use vegetation 'health' as a proxy for soil fertility (while obviously veg. growth is also correlated with temp. and precip., and soil moisture with topographic position), within a single field that presumably received the same amount of precip and sun, and where the...

I would also think a bit more about how you plan to use it, and whether you may want to fly with other apps than the DJI Go....? Some automated mission apps only work on i0S, others better/only on Android. Others on either/both...

when mine is far enough out that I can't see what direction its pointing in, I look at what the camera is pointed at, and then rotate it until I can fly it forward, back to me.

Robport, I'd sure appreciate some tips on what info. you include in your LANNC requests for authorization to fly in a 0 altitude area. I've been rejected each time (I've used KittyHawk to submit the request) (even though the particular aspects of where I'm asking to fly (on top of a hill...

I'm flying in the Gunnison area. I haven't flown elsewhere to compare to, but have not noticed any problems in performance. I'm hoping to go fly at 13,000 + sometime soon, to see what happens!

you should consider the "Ground elevation" data that Litchi has access to, to only be accurate to about +/- 10-30 m.........(less accurate for irregular terrain).....

Yes. dec. deg. vs. dddmmmsss seems more likely for 'miles off' rather than 000s of miles off...

It does seem like the coordinate readings are wrong. is it possible that teh Leica got set to lat/long or UTM even though you tried to set it to State Plane? I'm sure you'll have checked that, but it would be the explanation that best fits your observations. OR, I thought the whole benefit of...

When faced with this same decision 2 years ago, the Phantom's higher landing gear/clearance was an important factor for me since I am flying in rural areas with uneven ground/grass...(and the mapping focus). Have now 'graduated' to hand-catching ---and that landing gear sure comes in handy for...

I am currently consulting with some BLM employees who have all been explicitly denied authorization (internal memo, etc) to sign contracts to hire or collaborate with anyone who plans to use a Chinese-made UAV, so our collaboration has taken a different direction than originally anticipated...
