What is drone mapping and surveying?
A drone survey is the use of drones or unmanned aerial vehicles (UAVs) equipped with RGB cameras, multispectral cameras, or LiDAR payloads to collect data. And then this data is transmitted to special equipment on the ground near the UAV operator. The end result of drone land surveying is a finished map of detail at a given scale, presented in digital format.
Surveying drones can fly at much lower altitudes than traditional techniques like manned aircraft or satellites, providing high-resolution, high-precision images faster and cheaper, and independent of weather conditions such as cloud cover.
What are the benefits of drone survey?
Even the most novice user knows that drones can be used for photography. The availability of unmanned aerial photography has led to its use in many sectors and produced incredible images. But is it good enough for your next mapping or surveying job? Let's take a look at some of the advantages of using drones for mapping and surveying.
Save time and money
The economic advantage of drone land surveying comes primarily from its low operating costs compared to its main competitors, airplanes, and helicopters, which are up to 10 times more expensive than drone topography. Besides, recent studies show drone surveying is up to five times faster than traditional land-based methods.
Provide high data accuracy
Drones have extremely high accuracy, with aerial mapping reaching centimeter-level accuracy and mapping accuracy generally reaching 1:1000. In addition, aerial mapping also has a wealth of 3D geographic information, which can capture the data of large-scale terrain.
Map inaccessible places safer
Drone topographic survey allows us to obtain extensive and reliable data from inaccessible locations, unsafe steep slopes, or hazardous terrain. This means that surveyors can create a 3D computer model of the object under study and take a series of measurements in the office, without necessarily needing to be in the field or in a hazardous area to obtain data.
What is the best drone for land surveying?
As the best drones for land surveying, JOUAV CW Series VTOL drones provide a comprehensive drone surveying solution, which has released drones that can carry different functions according to the different needs of users.
A portable, integrated UAV platform that delivers exceptional reliability to our customers.
Multi-purpose and battery-operated intelligent VTOL drone
Long Endurance Electric Fixed-wing VTOL Drone
Hybrid Gasoline & Battery Medium UAV
Vertical take-off and landing (VTOL)
JOUAV VTOL drones (Vertical Takeoff and Landing) represent a hybrid approach that combines elements of quad-rotor and fixed-wing designs. They take off and land vertically like quadcopters, which means JOUAV drones can take off and land smoothly in narrow areas such as cliffsides, woods, or mountainous areas. Meanwhile, drones have the advantages of long endurance and fast flight speed of a fixed-wing drone, making them suitable for mapping large areas.
Up to 10 hours endurance/maximum load of 25kg
Through various methods such as aerodynamic optimization, power system optimization, and customized high energy density batteries, the JOUAV drone with longest flight time is 5 times longer than its competitors and can reach a maximum 10h flight time under heavy load conditions.
JOUAV drones can take orthophoto cameras, multi-cameras, gimbal cameras, hyperspectral cameras, multispectral cameras, atmospheric sensors, aeromagnetic and other mission equipment, and supports secondary development. The heavy lift drone can carry a weight from 0.8 to 25kg.
Down to 1cm (0.4 in) absolute accuracy
The JOUAV UAV uses both RTK and PPK modes. RTK is primarily used for precise centimeter-level autonomous vertical landings, and PPK is primarily used to output high-precision POS data to ensure a large reduction in image control points. The JOUAV RTK drone provides best-in-class absolute accuracy with vertical positioning accuracy down to 3 cm and horizontal positioning accuracy down to 1 cm, which allows the JOUAV UAV from high altitude to fly over and still provide low GSD images.
Flying in harsh environments
Through continuous power system optimization analysis and testing, the JOUAV UAV can fly efficiently at an altitude of 4,500 meters despite the thinner air. The drone is waterproof, ensuring that the aircraft can fly in light rain and snow. They can safely fly and collect data in winds of up to 12m/s 28 mph.
The easiest and autonomous drones to fly
After pressing the take-off button, the drone takes off autonomously on a planned course, captures images, and then lands where it started. The operator does not need to do anything else during this process.
JOUAV drones also support a Terrain Following Mode based on a high-precision digital 3D map. With this feature, they can automatically generate a variable height route based on the measurement area and maintain a consistent ground resolution for better data results.
The safest drone to fly
JOUAV drones' forward and backward sensors have a detection range of up to 240m and a wide field of view. So you can be sure it will catch all obstacles in its path and avoid them effectively, guaranteeing a safe flight. The downward sensors allow a measurement range of 50m that can be performed to avoid dangerous landing sites.
How to do drone survey with JOUAV VTOL drones?
Below you can learn how to do a land survey with JOUAV survey drones. You will know how to plan a flight, how to collect aerial images, and how to generate an orthomosaic map.
Check regulations and weather. Before flying a drone, you need to check local regulations to ensure that the drone is allowed to fly in the location you want to survey. Also, make sure there is no rain, fog, snowfall, or strong winds on the day you plan to fly.
Set up ground control points. When setting up ground control points, we need to consider the quantity, quality, and distribution. For a drone like the JOUAV CW series, which has an RTK module, we recommend that 5 checkpoints be set for each project, as the drone already has the ability to georeference the photos it takes with better than 1cm accuracy.
Set up overlap and flight mode. For most drone aerial surveys, the photo overlap should be set to 75/75 and the flight mode should be "lawnmower mode" or a sweeping flight path back and forth over the entire site.
Create survey flight plans with FlightSurv. You just need to click and drag points around the area you want to survey or import a KML file. When setting up, you'll need to set the flight altitude based on the accuracy you want and be aware of objects up to the height, and differences in altitude.
Fly and collect data. Now you need to unpack and assemble the drone, follow the interactive checklist and check each parameter one by one. After pressing the take-off button, the drone takes off autonomously and captures images without the pilot doing anything.
Post-analysis. After a few flights, you need to upload the images to a post-processing software that generates a 3D map or an orthomosaic map. Based on the images provided, you can focus on finding volume, geographic location, altitude, or damage.
Real-world case studies of drone mapping and surveying

Drone mapping FAQ
How accurate are drones for surveying?
The accuracy of drone surveying depends on the performance of the UAV, the quality of the camera, weather factors, flight altitude, etc.
Generally, drone maps produced using quality UAV equipment, careful flight planning, commercial-grade GPS ground control points, and commercial-grade processing software have the potential to be accurate to about 2-3 cm horizontally and 5-6 cm vertically.
What are the limitations of drone surveys?
Commercial drones can be a very useful tool for surveying projects in any industry, but they are not without any drawbacks. There are some limitations and potential complications to using drones for aerial surveying.
- Drones do not cope well with high winds. Drones are lightweight and small, so they can easily be deflected by high winds, preventing them from obtaining accurate results.
- Drones can be easily hijacked or manipulated. It is similar to hacking a computer in that hackers can intercept signals from a mile away to establish a connection with your drone so they can manipulate the gadget.
- Drones must be flown by someone trained in drone operations to obtain images and data in a safe and efficient manner; this increases the cost of using drones.
- Ever-changing drone laws. There is a range of regulations when it comes to the use of drones. According to FAA guidelines and regulations, drones cannot be flown over military bases, near airports, or in overpopulated and crowded areas.
How does drone mapping work?
Like satellite imagery, drones survey photos taken from the air or from a controlled altitude. Equipped with cameras of different capabilities, drones can produce high-resolution images.
When taking photos, the operator must check the maintenance and calibration of the drone. The drone mapping software then analyzes the photos taken by the drone, aligns and calibrates them, and creates a 3D model based on these photos.
In addition to photogrammetry, drones can carry LiDAR sensors to measure distances and object heights, allowing for more accurate surveys than satellite surveys.
What is the difference between LiDAR and photogrammetry?
Nowadays, survey drones can carry both LiDAR sensors and photogrammetry, which one should we choose?
This depends entirely on the specific use. In the field of forestry mapping, LiDAR is a significant advantage. Drone photogrammetry can only produce high vertical accuracy if the site is sparsely vegetated, while LiDAR can map denser vegetation and large areas of trees. But when it comes to the broader surveying needs of the construction, mining, and aggregates industries, photogrammetry is a more affordable solution with good accuracy and ease of use for most teams.
What are ground control points?
In aerial mapping, ground control points (GCPs) are points on the ground with known coordinates that are placed on the ground inside the UAV survey boundary. They are used to help UAV mapping software accurately locate your map with the real world around it.
What are PPK and RTK in the survey?
Post-processing kinematics (PPK) is a GPS correction technique that corrects position data after it has been collected and uploaded. Real-Time Kinematics (RTK) is another GPS correction technique similar to PPK, but it corrects the position data in real-time as the UAV measures and captures images of the field.
How to measure the location of drones in a drone survey?
The position of the drone in flight can be measured by ground control points (GCP), real-time kinematics (RTK), or post-processing kinematics (PPK).
What is drone mapping software?
UAV mapping software can be installed on a dedicated UAV ground control station (GCS) or on a laptop, tablet, or cell phone for stitching aerial imagery and LiDAR data collected by UAVs into 2D and 3D maps and models.
