Earth observation reveals the when and where of mangrove dieback

In the wake of the United Nations Climate Change Conference in Glasgow (#COP26) there’s even more than usual climate related information hitting the headlines. And this just landed from Professor Peter Macreadie and team from Deakin University (and others), reminding us to consider the role of blue carbon ecosystems (e.g. mangroves, seagrass meadows, and tidal marshes) in our climate change models

Top 10 Tips For Capturing Drone Mapping Data

How to map with a drone: I know that lots of people love flying drones, but I’m not one of them! Yet what I do love is the #earthobservation data that I can capture with my drone. I’ve been working with remote sensing data since the late 1990’s and know full well that not all data

Drone Pilots Reinvent Themselves as Mother Earth’s Paparazzi

Over the past seven years, I have captured tens of thousands of beautiful drone images. But I don’t consider myself a skilled photographer – I’m simply lucky that my subject is stunning! And while many photographers around the world may compete to take the prettiest or most beautiful photo, I’m adament that this is not what I

Let’s Talk About Drone Crashes

It doesn’t matter if I’m talking to kids or adults, the most common question I’m asked about droning is if I’ve crashed. And while I can’t say that watching a 35kg beast crash is the highlight of my career (manufacturer error, I swear!), I have the following mantra: as long as no one is hurt,

How can I get ground control in a marine environment?

I’m sure that my certified surveyor friends cringe when they hear about our methods of ‘Marine ground control’ on the reef! But here goes… What is ‘ground control’? No, we’re not calling Major Tom… Ground control points (GCPs) are points or features on the surface of the earth (or even underwater) with a known location.

Ten Tips for Catching a Drone Safely

I often joke that drones are like flying Edward Scissorhands. Those propellers can really do some damage if they come into contact with anything other than air! Just check out how the drone below is able to slice and dice for your daily smoothie… So why on earth would I want to have that anywhere

Drone data…don’t lose it, use it!

I consider myself to be a biographer for Mother Earth. I tell stories of her beauty, challenge, and change, using drones and satellites as my scientific illustrators. Over the years I have amassed many ‘photo albums’ of Mother Earth; seen the progression from expensive and siloed, to open satellite data archives; and now particularly enjoy

How high should I fly for drone mapping?

People frequently ask about how to calculate the optimal drone flying height, however, it’s the wrong question to ask. What is more important is to understand the size of the feature/s that you are trying to map. It may come as no surprise that as you increase the altitude of your drone, you are able

What is an Orthomosaic?

Orthomosaic, the Short Answer: The output from a process where a number of overlapping photos (e.g. from a drone or aerial camera) are stitched together with distortions removed to create a complete and continuous image representation or map of a portion of the earth. The orthomosaic below is made up of 283 individual drone photographs.

Spectacular drone mapping on the Great Barrier Reef to find live coral

As a student in the late 1990’s I was incredibly fortunate to visit the University of Queensland Heron Island Research Station many times, firstly for undergraduate subjects, and then later for my own research. I became fascinated with working out how we could use remote sensing technologies to figure out how much live coral we had on

Up and away! The best time for drone mapping

One of the things that I love about working with drones is the ability to be flexible about when and where I fly to capture data. I’ve worked with satellite data for over two decades and it can be really restrictive when data are only acquired at a set time of day, and only when

How to drone map on a family camping 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 it makes perfect sense to be on the beach in July – in fact, it’s the best

How Artificial Intelligence (AI) makes drone data processing smarter

If you search “AI”, there are more than four trillion results in Google. If you search for “AI” in news, there is a piece released almost every hour about this topic. Artificial Intelligence (AI) is truly a ubiquitous word these days. Some are even asking “What can’t AI do?”. The terms of AI are overwhelming.

3 machine learning concepts you need to know if you love drones

We’ve been talking about artificial intelligence (AI),  drones and machine learning for a while now. However, do you feel that sometimes it’s just a bunch of fancy words flying around? In this article, I would like to introduce three basic machine learning concepts for those who love drones. No matter why you love flying drones,

Catastrophic fires a high price to pay to reduce dust

It might have been planted to suppress dust and provide cattle fodder during a drought in central Australia, but buffel grass has taken over the landscape with disastrous results. As an invasive species, buffel grass is able to take advantage of conditions that are not so friendly for native grasses. In particular, it can grow

Don’t clam up on me!

I have to confess that I absolutely LOVE clam chowder. I remember when I was first introduced to it at Phil’s Fish Market and Eatery in Moss Landing, California – 20 years ago! Phil’s is an institution and the chowder in a chewy sour dough bread bowl on a crisp day by the Pacific Ocean

Moo alert! We want to create an outstanding pasture for out standing cows!

Cattle are definitely one of the rock stars in human history. They have been contributing to our society as draught animals, providing resources such as meat, milk, leather, fertiliser, by-products and as trusting companions and possessions. Why did the cow get an award? For being out-standing in the field. (Photo by Wolfgang Hasselmann on Unsplash) However,
