Open Data: there’s no such thing as free

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 became…

What is the resolution of drone mapping?

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….

Earth observation data reveals the when and where of mangrove dieback

Earth observation data reveals valuable information that you should know. 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,…

Calling drone pilots help map the sea cucumbers population

Sea Cucumbers have threatened species and it’s critical we create the largest population map of their habitats. The first time I flew my drone on Heron Reef about five years ago I was blown away by what I would now be able to map and monitor. I was looking for live coral and I certainly…

Drone Pilots Reinvent Themselves as Mother Earth’s Paparazzi

Mother Earth’s Paparazzi is a term used to describe drone enthusiasts who capture images of mother earth to help protect at-risk ecosystems. 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…

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….

How to figure out the optimal drone flying height for mapping!

How to figure out the optimal drone flying height for 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…

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…

Using Drone Data to understand Clam Reefs

Using drone images of clam reef, we estimate the amount of live tissue & model their contribution to the calcium carbonate of the reef. 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…
