Drone Mapping & Surveying: Benefits and Applications (2023)

Drone surveying saves valuable time for land surveyors, allowing safer working conditions, better data, and more accurate 3D models. 

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.

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.

Which software for drone surveys?

FlightSurv is an easy-to-use UAV mapping software designed specifically for professional uses. This cloud-based software can be used as a mobile application for a single user or as an enterprise customer with any number of users.

There are many autonomous flight features and options within the software, including checking drone equipment and supporting multiple missions.

The platform is feature-rich and full of cloud-based operations that can be easily managed even if you have many team members or clients who need your drone data on their own mobile devices.

How much does a drone survey cost?

Generally, the average cost to hire a drone survey company is between $30 and $120 per mile. This cost may be higher or lower than that, depending on the type of drone survey, the size of the project, the desired accuracy, and the needed output.

How much does LiDAR charge for mapping?

A drone with LiDAR for aerial mapping costs $2,500 per day, while a manned aircraft LiDAR system can be as much as $30,000 per day.
