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
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
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
Many people use drones for mapping to achieve greater resolution when compared to traditional aerial photography or satellite imagery. But what does ‘resolution’ really mean when considering remotely sensed data? There are actually three main types of resolution relevant here: spatial, spectral, and temporal. Let’s explore each below in the context of drone data collection.
Drones used for research: My name is Valerie and I am currently a PhD student at James Cook University. My project consists of modelling coral bleaching predictions and therefore, it fundamentally requires spending a lot of time in front of a computer. Although coding may not necessarily be every marine biologist’s favourite part of research,
Learn how to pack the bare minimum when taking your drone surveying equipment on a family holiday. It’s school holidays in Queensland and what better time to get out and about camping! It might be the middle of winter for most of Australia, but that seasonal description doesn’t really fit in the tropical north. So
DJI drone comparison: Facing off against each other we have the Autel Evo II Pro and the DJI Mavic 2 Pro… In many ways they are so similar that one might think they have come from the same factory or is it just a case of parallel evolution? Regardless of the intellectual property claims, let’s
Let us explain the difference between CPU vs GPU in the process of deep learning. Recently, I had an interesting experience while training a deep learning model. To make a long story short, I’ll tell you the result first: CPU based computing took 42 minutes to train over 2000 images for one epoch, while GPU based computing only took
