What is an Aerial Survey?
Picture this: You’re standing on the ground, looking at a vast stretch of land, trying to make sense of it all. Now imagine you could zoom up to the sky, see everything from above, and get precise measurements without breaking a sweat. Sounds pretty cool, right?
Well, that’s essentially what an aerial survey does. It’s the process of collecting data about the land from the sky, usually with drones or aircraft. This method is way more efficient than traditional surveys, which rely on measuring things manually on the ground. By flying over the area, drones capture high-resolution images and data, which are then turned into detailed maps or 3D models. It’s like giving surveyors a superhero power to see the big picture!
How Do Aerial Surveys Work?
So how does this magical bird’s-eye view happen? Here’s how it goes down:
• The Drone’s Journey: A drone, or UAV (Unmanned Aerial Vehicle), is given a set flight path. Think of it like a map for the drone to follow during its flight. This flight path ensures that every part of the area gets covered.
• Sensors & Cameras: As the drone zooms around, it captures images and data using cameras and sensors. Some drones even have fancy gadgets like LiDAR (that’s Light Detection and Ranging, if you’re into techie terms) that measure the height of things, like trees or buildings.
• Putting It All Together: After the drone finishes its flight, the data it’s collected is fed into a computer. There, clever software stitches the images together, creating one large, seamless map. This can even be turned into a 3D model that shows the landscape from every angle!
What Kinds of Tech Does an Aerial Survey Use?
• LiDAR: This technology shoots laser beams at the ground to measure how far away things are—super handy for getting precise elevation data.
• Photogrammetry: This process turns regular photos into a 3D map, kind of like how Google Earth shows a 3D view of the world.
• RTK/PPK GPS: These are super accurate GPS systems that make sure everything is exactly where it’s supposed to be.
What Can Aerial Surveys Be Used For?
Aerial surveys are not just cool, they’re also incredibly useful in so many industries. Here are a few ways they come in handy:
• Land Planning & Development: Need to map out a new suburb or a big construction project? Aerial surveys can help you plan and measure everything accurately before breaking ground.
• Agriculture: Farmers use aerial surveys to check on crops, monitor soil health, and even detect issues like pest infestations—without walking the whole field!
• Environmental Monitoring: Whether it’s tracking deforestation or monitoring wetlands, aerial surveys help environmentalists keep an eye on things that are hard to access.
• Mining & Resource Management: Aerial surveys help miners get a better understanding of the land they’re working with, helping them to plan more effectively.
• Disaster Response & Recovery: After a bushfire, flood, or storm, aerial surveys can quickly assess damage, locate survivors, and help emergency teams respond faster.
Why Are Aerial Surveys So Awesome?
You might be wondering, “Why bother with all these drones and fancy sensors?” Well, here’s why aerial surveys are a game-changer:
• Speed & Efficiency: Drones can cover vast areas in record time. What would take days or even weeks on foot can be done in a few hours, saving you time and money.
• Access to Hard-to-Reach Areas: Some places are just too difficult (or dangerous) to get to on foot—like cliffs, dense forests, or disaster zones. But drones? They don’t mind! They’ll zip over, capturing all the data you need.
• High Accuracy: Drones come with advanced sensors that provide incredibly precise data. Whether it’s measuring the height of a building or mapping out a mountain range, you can count on the accuracy.
• Cost-Effective: Traditional surveying can be pricey—lots of people, lots of equipment, and lots of time. Drones are more affordable, making aerial surveys a cost-effective option for most businesses.
• Real-Time Data: With live video streaming and rapid processing, drones provide immediate information, making them perfect for emergency situations or decision-making.

Frequently Asked Questions (FAQ)
What’s the difference between aerial surveying and traditional surveying?
Good question! Aerial surveying uses drones to capture high-resolution images and data from the sky, which is then used to create maps and models. Traditional surveying, on the other hand, relies on manual measurements taken on the ground. Aerial surveys are faster, cover more area, and are often more accurate.
Do I need special permissions to conduct an aerial survey?
Yes, in Australia, you’ll need a Remote Pilot License (RePL) to operate drones for commercial purposes. Depending on where you’re flying, you might also need specific approvals if you’re flying in restricted airspace. But don’t worry—our team at Two70° handles all that for you!
How accurate are aerial surveys?
Aerial surveys can be incredibly accurate, especially with advanced GPS systems like RTK and PPK. Depending on the technology used, the accuracy can be within a few centimetres!
