While multispectral imaging may have been developed as a military surveillance technique, these days its benefits are far more wide ranging. From Earth observation sensors on satellites to laboratory based systems, they can be deployed to detect, identify, and measure features invisible to the human eye at a variety of scales. Let’s look at how
What do crocodiles and GeoNadir projects have in common? We both love snapping! But of course in vastly different ways 🙂 When we snap as part of creating insights with our drone mapping data, this is a good thing. Not something to be afraid of! So what is snapping, and how can it help us
Move over ChatGPT, there’s a new AI kid on the block! Just this week MetaAI released a new tool called ‘Segment Anything’ (Meta is best known as the Facebook parent company). And it’s unleashed the same fears and excitement as many tech tools before it. As someone who has been segmenting Earth observation imagery for
Over the years we’ve become accustomed to reusing, recycling, and upcycling a wide variety of different products and materials. At the same time, a greater awareness of the health and environmental impacts of practices such as fast food and fast fashion have also led calls for more sustainable ways of living. Collectively, this opens discussions
People often ask me what inspired me to create GeoNadir. To be honest, first and foremost it was selfish intention to make my life easier. Since 2013 I have amassed a huge amount of drone mapping data, and I’ve always had the problem of how to store, process, and share it in a simple workflow.
Here at GeoNadir, we want to create the biggest repository of free drone image datasets and 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
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,
Photogrammetry is the science of taking measurements from photographs. We can make photographic measurements using photos taken at ground level, from aerial platforms, and even underwater. One of the most important elements of photogrammetry is taking lots of photos with high amounts of overlap between adjacent pictures. Aerial photogrammetry was initially limited to organisations
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
For the past 20 years, open data has been rapidly changing the face of earth observation applications and innovations. Twenty years ago (yikes!) Luther Vandross and Janet Jackson crooned ‘the best things in life are free’ and it seems that Barack Obama agreed. By the end of 2008, the entire archive of Landsat data
