In this video we show how portable ground control Points increase accuracy for drone mapping data acquistion and reduces onsite time and overall project costs. We demonstrate how to use the Propeller Aeropoint versions specifically.
-Steel City Drones offers both online mapping classes as well as in person classes.
-We are the only drone school that will train your staff at your facility to keep training costs low.

Very excited about recent developments in survey drone mapping. I remember a professor in a photogramatry class 10 years ago telling us drones were the future and we laughed at him. Guess we weren't as smart as we thought!
Thanks for the input and feedback.
it is so excited
So I just passed part 107, practicing this with a anafi thermal and trial of pix4d. I am noticing even after calibrating the drone where the flight path overlay and the map of my house from wherever it's getting the satellite imagery is offset by like 10 ft. Not sure if it's the GPS on the drone being not accurate or satellite imagery of my house that is offset. It's also missing the sides of my house but it is working mostly.
It's not uncommon for projects to be off 10-40 feet if you do not use Ground Control points. And the only way to really validate your data is to use Check shots using Trimble hand helds.
Is there an example video with a drone in flight mapping out an area? Great information by the way. Thanks!
can i mark points with remote m300 rtk and rtk base station without aircraft?
Which points are you referring to? Ground Control points are independent of the M300 and base station.
@@SteelCityDrones I need to get the ground point and don't need M300 on. Use only smart controller and D-RTK 2 base station
@@mmong626 Ground control points have nothing to with the M300 on or off.
I didn't understand the part where they said arrow points are useful for relative accuracy.
The way I understand it, drone maps are relatively accurate without ground control. Ground control (AeroPoints) is useful when you want to put the Drone map on a particular place on the earth, which is absolute accuracy.
I watched this again and I did not here Steve say that. He explained the difference between relative accuracy and absolute accuracy.

"Rtk is important for absolute accuracy and ground control points are important for relative accuracy".
Am I misunderstanding something?
@@SteelCityDrones
Also, at 1:55 he says that "the relative accuracy is where a point is on this globe and relative accuracy is..."
He said relative accuracy twice. One of them should have been absolute accuracy unless I'm misunderstanding. something.
Thanks for reading these comments and taking the time to respond 🙂
@@jerseyshoredroneservices225 Absolute accuracy is a point that's a specific spot on earth, relative accuracy is a point that's accurate compared to other points around it.
First of all, thank you for sharing this great information. But I have one more question. What is the difference between Areopints and Reach? It would be my pleasure if you can help me to know the difference between these two systems.
Wow! 🤩
So if you have the rtk with ground station do you still need control points?
There are a lot of factors that go into that. One thing you definitely should have are check shots to validate your data. You can have the best data but if you can't validate it, the data is useless. Check shots are taken from Trimble Rovers that most engineering companies use.
@@SteelCityDrones thx
thank you for your informs~~
Did he say $6000? Damn.
The key phrase here is " you have to pay a Surveyor", when AIs take this over standard surveyors will be out of work...
In the United States it is illegal to advertise "survey work" without being a licensed surveyor. Survey work is considered to be line work, CAD deliverables, and a stamped seal signed off and certified by a licensed surveyor. Most people don't have a Trimble R10 that can set Ground Control or Check shots so they pay a survey tech to collect that data for them.
6k ???
Why would I not get a rover
On average, you can pay a survey tech between $1000-$2000 per job to lay down ground control points. If you do 3 to 4 mapping jobs the portable control points pay for themselves. In addition, you can use the Portable GCP's as a reference check shot that you can calibrate the base station, and or use additional check shots to validate data.
@@SteelCityDrones not in the UK....
If your lucky get a student or trainee and probably for around £180.
Things are not the same the world over.
@@Guide504 Sorry your reply is not understandable.
@@SteelCityDrones slang for cheap intern in the UK.
Recommend you call them Temporary control points.
-A surveyor.
