Everything you need to know about drone surveying

By JohnBarnes

Drones can be a powerful tool for the mapping and surveying industries. Drones can be used to perform 3D mapping, topographic surveying, photogrammetry and land surveys above the ground. This article will cover everything you need to know about drone surveys, whether you’re looking to add another tool or learn more about the industry. HeliDrone survey has been providing aerial UAV surveys for many UK companies since 2014. Drone survey company London can help get to those places that would be difficult to reach by conventional methods.

What is a drone survey?

Surveying, in general, is the science of determining distances and positions between points. It can be done in either a 2D or 3-D space. This information can be used to make important decisions regarding infrastructure maintenance, site planning, and property boundary delineation. You can use the same principles to create a drone survey. The drone will fly over the points and collect all information.

What is a Drone Survey?

The drone is able to capture images by using its downward-facing sensors that have multispectral and RGB cameras. Many drones also have LiDAR payloads that can be used to collect data. The drone will use the RGB camera to take photographs of the ground from different angles when it surveys the land. Each angle is marked with the coordinates.

How do drones collect data?

The Geographic Information Systems (GSI) is used by drones to collect data. This information was used to map and visualize locations. While the GIS is the main source of data, other tools for collecting data can also be used on the drone. Drones were previously used to transmit but not capture data. The operator had to retrieve all that data. Drones can now interrupt data in real time using new technology. GIS technology can transform all the raw data into actionable information while the drone is still in flight.

What drones are used for surveying?

There are many commercial drones available on the market. You should ensure that the drone you choose can perform surveying. Multirotor drones are common, but a fixed-wing motor can be beneficial for mapping surveys. Multirotor drones can be easier to fly but fixed-wing models are more useful when you need them for surveying a few hundred acres at once. Fixed-wing drones can glide through the air faster than multirotor units and remain in the air for longer periods of time.

Aerial mapping requires that you fly your drone over the same area multiple times. You might consider buying one that can be programmed to perform autonomous flights. You will need software to create a flight plan if you are unable to activate an autonomous flight. Once you have done that, you can send the information to the drone’s remote controller for a pre-programmed flying.

Aerial surveys, as mentioned previously, require that you cover a lot. Multiple drones can’t cover many hectares in one battery cycle. It can be time-consuming to land and deploy your drone multiple times. A commercial drone should be able to fly for at most 30 minutes without interruptions. This will allow you to complete the survey without needing to change batteries.

Photogrammetry is used to catalog data for aerial surveying. To determine the ground’s dimension, this technique relies on overlapping geotagged photos. Your drone must have a camera capable of capturing 4k videos and 12MP photos to be able to perform 3D mapping tasks.
