There are various kinds of drones available in the market. Every drone is capable of doing different jobs. The category of these various drones varies from basic drones to high-level drones. Mapping drones are considered as one of the best and high-quality drones in the market. These drones are capable of constructing flat maps, 3D maps, Surveying and even more. Aerial solutions did not just about the aircraft, it was more than that. It involves UAV solutions, complete with all the tools geospatial pros need to perform jobs accurately, efficiently, and safely.
Why do Drones become a Popular Device for Surveying?
Mapping drones have proved themselves as the most powerful equipment in this field. They are providing a lot of features. Some of the features are:
- They provide safety
Some areas are difficult to access like challenging terrain, crumbling structures, high locations, and areas affected by natural disasters. These locations can cause serious injuries to workers or any other person present there. Drones perform various allotted tasks and provide people with a safe zone to work.
- They are more efficient and also saves time
As drones work on the basis of programmed data and instructions l, they work more efficiently and collect field data more accurately and within a very short span of time.
- Gives a competitive look in the market
People nowadays are counting on UAV’s surveying more than anything else. Providing UAS mapping service gives companies a clear and standard look and customers also trust them on the basis of UAV surveying.
- It expands your offering
You can easily increase the number of offers to your clients. By installing these payloads and technologies in your system you can offer more services to your clients which can result in more clients and increased goodwill.
Here we will review some high-quality drones which are highly programmed to learn new things fast and at the same time can be accessed easily.
DJI Matrice 300 RTK is one of the safest machines in the sky. It promises many applications to the users which makes it one of the most popular drones in the market. It has the best obstacle avoidance and aerial awareness tools are included in this platform. RTK GPS capability, along with Airsense ADS-B tech and a bunch of Smart tools, offers the best accuracy and safety when you fly this drone. It offers a great flight distance. Users get a flight distance of 15 KM i.e. up to 10 Miles. 10 miles is a great distance capacity for capturing or collecting data from any site. The camera specifications of DJI Matrice 300 RTK is also great. It has the new Zenmuse H20 payload which is a powerful camera system. It comes in two versions, first is H20 and the second is H20T. A 20MP lens with 23x zoom features is installed on both cameras. They also feature a 12MP wide-angle camera with a laser range finder.
Yuneec H520 can be considered as a drone that features great specifications. Yuneec recently designed some hexacopter designs which become the talk of the town. After that success, Yuneec decided to head over the commercial drone market and launched Yuneec H520. This flying beast is constructed only in orange design. It is a foldable drone that offers a range of payloads that allows inspection, surveying, mapping, and search and rescue needs. It has retractable landing gear which allows 360-degree rotation of the camera. Yuneec claimed that the H520 is capable of flying with superb stability in heavy winds. The drone can be controlled within a radius of 1 mile and can fly with a maximum speed of 38mph.
Mavic Pro by DJI was a great success and by observing that, DJI launched their new commercial drone DJI Mavic 2 Enterprise. The Mavic 2 Enterprise works on the same platform as the Mavic 2 Pro, Mavic 2 Zoom and Mavic Pro Platinum. It has some new features and accessories. It is designed for tasks such as search and rescue, with a spotlight, loudspeaker, beacon, and more. It comes in two versions, both have the same specifications and design except the camera. The zoom addition uses the same camera as DJI Mavic 2 Zoom but the dual editions add a thermal camera to the mix and remove zooming from the visual camera. The drone offers a maximum speed of 44mph and a range of 4.3 miles.
DJI Mavic 2 Pro is an upgraded version of Mavic pro. It instantly became the best consumer class folding drone by DI in the market. This drone got serious upgrades and comes with a 1-inch camera sensor for 4K video recording at 100 MBPS. It even has a multi-direction obstacle avoidance sensor for the safest drone flight.
OcuSync 2.0 enhances connectivity to the remote control and other accessories, now able to transmit 1080p live stream video well beyond the legal line-of-sight. DJI upgrades their drones from time to time and the Mavic 2 pro captures the market when it comes to features with affordability. The drone has a battery life of 3820 Mah and can fly at a maximum speed of 44mph.
The Parrot Anafi is considered as the best entries by parrots in the drone market. This drone costs much less than others on the list and offers great features. The new 21 MP 4K camera setup works amazingly and points up and down in all directions and in all pointing ways. This is an extremely powerful commercial drone that is built user friendly in a folding quadcopter design. Anafi is made up of a plastic body and is very light which helps to provide a great flight and battery time. Other than this, Anafi has some common features such as folding propeller arms, folding propellers, a compact size, and a stabilized 4K camera. The remote controller has a section where you have to connect your phone so that you can control the drone in a better and more digital way. You can also carry spare batteries with you for longer flight time.
How is 3D Mapping done by Drones?
There are many photogrammetry software that is used by drones for constructing 3D mapping. When it comes to photogrammetry software, users have quite a choice. There are many 3D mapping companies in the market which provide a free version trial. They actually allow you to try the software before you purchase it.
There is also some photogrammetry software that allows cloud storing or data warehousing. Photogrammetry software can create massive files, depending on the number of images and resolution of the images. Some photogrammetry software is like DroneDeploy 3D mapping mobile app Pix4DMapper photogrammetry, DroneDeploy Enterprise 3D Map, AutoDesk ReCap photogrammetry, SimActive Correlator3D™ software, Maps Made Easy orthophoto and 3D models, 3DF Zephyr photogrammetry software, Agisoft PhotoScan photogrammetry, etc.
How accurate is a Drone Survey?
Accuracy of a drone survey depends on many factors related to the drone, like the camera resolution, the height at which the drone flies, the vegetation, and the method and technology used to geolocate the aerial images can affect the accuracy of drone survey mapping a lot.
Steps to do a Drone Survey
- Check basics
Make sure before getting out of your office that the place you are going to fly your drone is legal for drones. Also, check if the weather is good or not. Weather should be pleasant for a perfect flying experience. Avoid weather like rain, fog, snowfall, or strong wind. Also, check that both your devices i.e. the drone and the connected tablet/phone are fully charged.
- Flight planning
You can easily create the survey flight plan with the drone flight planning app. For applying this feature you just have to drag the points around the area that you want to survey. The drone will automatically start the survey… Make sure you account for tall objects within the flight plan, as well as altitude differences.
- Set up your flight in the field
This step basically contains the process where you unpack your drone and assemble it. You should make sure first that the drone is ready to take off in a safe position. You should also check some other points like a check every parameter, like the calibration of the airspeed sensor and making sure the camera lid is removed.
- Fly and collect images
Now the drone will automatically take off and start collecting images. You just have to make sure that no one approaches the drone during takeoff or landing. The weather should be pleasant for the survey mission.
This review was about mapping drones. Mapping drones are playing a crucial role in today’s world. They can be considered as a great example of technology development. We are expecting a lot more advanced technologies in drones in the future. Today’s advanced drones are capable of making 3D maps and navigation systems, we just can’t think what capability they will have in the future. Different mapping drones come with different features and also have a good price difference. You can choose one by comparing the reviews above.
