What can you do with a drone?

In the past decade, drone technology has advanced from clumsy, expensive, DIY kits to sleek, user-friendly, commercial models. Each new improvement and advancement in processing software has expanded the number of fields where drones can help solve problems. It can be hard to keep up, especially if you’re someone without a remote sensing background. So…

Rangeland management: A remote sensing perspective

Drones and their data processing software continue to evolve. As they do, we discover new ways to collect and process data. As the storyteller for GeoNadir, I’ve had the opportunity to talk to lots of amazing people who work with drones. This week, I spoke to Dr Jeff Gillan from the University of Arizona. He’s…

Uploading an image collection: What info should I include?

Here at GeoNadir, we want to create the biggest repository of free drone mapping imagery from around the world. We want to make sure that all drone data is FAIR (Findable, Accessible, Interoperable and Reusable) so the treasure trove of knowledge stored in drone images can be used by people all over the world to solve…

Drone surveying: The new go-to for measuring elevation

Drone surveying: The new go-to for measuring elevation

Accurate topographic data supports emergency management strategies, land-use planning, mining operations, and many elements of environmental research. Thanks to NASA’s Shuttle Topography Radio Mission (STRM), most of the earth now has at least 30m resolution elevation data. But for many projects, this just isn’t enough detail. Drone surveying presents a new, flexible, affordable method for collecting elevation…

Types of environmental sensors for drones

Types of environmental sensors for drones

Drones are an extremely useful tool for capturing large quantities of high-quality environmental data. But you might not realise just how much data you can capture with them, especially when you start adding sensors. So here’s a rundown of the most common types of environmental sensors you can use with a drone, and the data…

How drones are improving landslide risk management in Brazil

If you were watching international news in February, you would have heard about the devastating landslides that swept through the Brazilian city of Petrópolis. Extreme rainfall along the Serra do Mar range triggered 269 landslides. Combined with flash flooding 217 people died and more than 850 homes were destroyed.  While this natural disaster was undeniably catastrophic, it…

Dryland salinity and drones: Managing salinisation in WA

If you’re a farmer in Western Australia, dryland salinity is an old enemy. It takes productive pastures and croplands and turns them into barren, salty fields. In southwest WA, dryland salinity has caused the loss of over 1 million hectares of productive agricultural land. A further 2.8 to 4.5 million hectares of productive land is at risk…

Mapmaking made easy: Introducing the create feature

Mapmaking made easy: Introducing the create feature

If you’ve been looking at the GeoNadir platform recently, you would have seen that it’s had a pretty big update. Making maps with drone orthomosaics is now easier than ever with GeoNadir’s cool new feature called “Create”. This new feature lets you draw on, label and measure your orthomosaics directly on the platform! So what…

Understanding the cycles of coastal lakes and lagoons

Intermittently Closed and Open Lakes and Lagoons (or ICOLLs for short) are a common ecosystem near many coastal towns. But despite being on many people’s back doorstep, local communities often misunderstand them. This makes managing these systems tricky, especially when what the environment needs isn’t what the community wants.  Stories from Above is about learning…

Fixed-wing vs multirotor drones: Which is better?

Fixed-wing vs multirotor drones: Which is better?

There are lots of advantages to using drone mapping over traditional survey techniques or satellite imagery for data collection. But to make the most of drone mapping, you want to make sure you’re using the right equipment, and that starts with picking the right drone. What are the options? When people think of drones, multirotor…

Rivers of ice: Using drones to understand glaciers

It’s not news that glaciers are retreating globally. In recent years, the steady retreat of glaciers has been one of our most visible indicators of climate change. Between 1994 and 2017, 6.1 trillion tonnes of ice was lost from the world’s glaciers. But understanding the relationship between climate change and glaciers isn’t as simple as…
