I was awaiting the drone survey series eagerly. I am glad to know that drones costing less than 1000 dollar along with GNSS receiver (which I think can also be available at reasonable price) produce orthorectified orthomosaic with relative and absolute accuracy. Looking forward to image processing and more next. You explain really well.

A few tips for the presented film: 1. Mark your elements that they do for GCP (adding numbers on the lids will make you see the GCP number in the photos, at the same time naming the GCP will be easier) 2. As far as I know, giving GCP right in the middle does not seem to affect accuracy. Have you checked how it is in practice? 3. The drone flight path selected by you is not optimal in time. The flight path should be aligned with the longer sides of the flight. This will result in fewer turns of the drone and shorten the flight time (will allow you to fly a larger area) 4. You talk in the movie about setting the capture interval to 1 second. The interval should be selected according to the possibility of taking pictures by the drone's camera. Few cameras can take pictures with a speed of 1 second. I have a question: a) Have you used any Trimble DA2 solutions? It looks like a much cheaper solution when it comes to purchasing GNSS equipment and comes out cheaper for occasional use (prepaid method $ 100 for 10h of online use) b) will you continue this series? GREAT MOVIE. MAY THERE BE MORE OF THEM. Greetings from Europe
@RamiTamimi2 жыл бұрын
Yea typically I'll put a survey stake next to the point with some ribbon to see it from far away with larger sites. I typically put one GCP in the middle of the site. I get that the outside ones are enough for a interpolated calculation, but having one in the middle could help shorten the distance between the exterior GCPs. You are correct about the path I took not being the most efficient. But being only a few minutes and just a quick crash course on drone mapping, I figured I'd save the tip for another video. Manual time interval flights usually are 3-4 seconds typically. I haven't used any Trimble products. I have Sokkia and Emlid, and I found the Emlid has the same results as my Sokkia, so I tend to use it more since I like the interface. Yes of course, the series will continue, make sure you subscribe so you don't miss out!

A GCP in the center of your worksite is necessary if you are not using coordinated cameras and you are using Structure in motion (Computer detects points outside of your ground control) photogrammetry, especially on large sites. It helps to identify and correct an error called doming that can occur if your lens model is incorrect. Doming is when your model is domed or dished compared to reality (i.e. the center is higher or lower than it should be). Over large sites (1km x 1km) i have had 2m on a check mark in the rough centre. Took me ages to figure it out. Establishing a good camera & lens model is key to good photogrammetry: For non coordinated photos (i.e. the drone has autonomous GNSS) I have a minimum requirement of GCPs at the external corners of my survey, one GCP at the center, one GCP at the highest point i can, one at the lowest point i can. The high and low points are to help determine my focal length (you can skip these if you are not concerned about heights). For Coordinated photos (i.e. the drone has differential GNSS -PPK or RTK) I take photos at 30 degrees from Nadir(down) and with that I only need check points to confirm my coordinate transformation (since in Australia GDA2020 has a well defined transformation from IRTF and hence WGS84). this is because the software can accurately determine focal length by comparing photos taken if opposing directions and can adjust focal length to ensure they match. If i only need an ortho image then ill just use nadir photos since it makes very little difference horizontally. You can precalibrate your lens by doing flights over a good number of coordinated GCPs but i prefer to calibrate within each job and compare it back to my baseline. Just remember over time calibration drifts much like Total stations so you do need to calibrate at regular intervals (e.g. one year). Note: the phantom 4 RTK has been pre-calibrated by DJI and its calibration parameters stored in each photos EXIF data if you want (and you dont have an exif data editor) open the file in notepad (preferably notepad++) and do a text search for something like "Focal" which will take you to the EXIF data in the photo.

That was interesting! As a pilot, I thought you were going to say, the number one thing is "safety"! :-) The pre-planned route and the GPS control point marking was pretty cool. It might be good to let folks know that one needs to obtain a FAA issued Part 107 remote pilot certificate, register and mark each drone separately with the FAA, (and to get an airspace authorization if operating in controlled airspace) in order to use a drone to do aerial surveying in US Airspace, since aerial surveying is not recreation, and must be flown according to 14 CFR part 107. Very interesting video! Thanks Rami!

Oh yes, surveyor's should be the only ones to set control points, and Part 107 Pilots (been one since 2017) should be flying drones commercially. "Safety" is the number one priority when operating drones, good data when processing it ;)

This is great Rami, thank you! I came into drone work from photography so getting the "pretty picture" part of it to be beautiful has been very important to me lol. After 2 years of practice flying photogrammetry missions and processing the data without gcps I'm ready to actually start doing "surveying" and marketing the work. Really hoping to team up with a local surveying company. I'm not a licensed surveyor so no matter how good my work is it cannot be called a survey unless I partner with a surveyor. I'm very excited about the possibility of producing accurate measurements and contour lines on my pretty pictures 🙂

Great video! As a complete beginner, I am wondering how you were able to move around a single base station receiver to gather all the GCPs. I thought that 2 base stations are required to do that, one fixed and one as a mobile rover? Are you connecting to a local subscribed Network Connection Service to do this? I'd love to understand why a single base station receiver cannot be moved around to gather the data from the various GCPs without connection to a local Network Connection Service. Would you be able to comment, or maybe make a video to help us novices understand?

Thanks a lot for this video. Got a question for you... If a water survey drone only completes 11 out of the scheduled 24mins survey time and keeps disconnecting several times, 4 -5 times during its flight then aborts the mission before completing the entire flight as the battery was too low. It tried to return home but failed to successfully do so and ended up descending in the bushes far from Home - Does this mean that the survey data was successfully collected as we are being told? The drone used was exactly the same as the one in this video.

You are a natural for explaining this stuff! So I have a question about Drones with RTK being used with a base station. If you don't have a known reference point to input in the base station and don't have access to a NTRIP server, when you are using a RTK base does it make a difference in the accuracy? Or do you have to have a known point or access to NTRIP? Thanks!

This may sound like an odd question. But I would appreciate your thoughts regardless. I have a piece of property adjacent to mine. It's basically a rectangle. An open area of perhaps 15 acres. Someone put down ground control points in a straight line along the center of the property. Parallel to the longer sides of the rectangle. Is there any reason someone would do this in order to survey the property? My wife asked him what he was doing. He said surveying. I am more inclined to believe he's monitoring the property as we've had illegal hunting going on. A line in the middle would make way more sense. But maybe I'm missing something. Thanks and regards.
