Mapping the bathymetry of the Mediterranean
When most people think of the ocean, they think mostly of water, not the land that lies underneath it. But bathymetry, which is the study of water depth, is critical for understanding our coastlines. Water depth influences currents, waves, and where different marine life can live. Like topography on land, drone mapping can help collect […]
Mangrove conservation – How can drones help?
Mangrove conservation is a pressing global concern. These habitats are highly productive ecosystems that offer many environmental services. Mangrove forests store nearly 10 times more carbon per hectare compared to terrestrial forests, playing an important role in the fight against climate change! They also safeguard the coastlines of tropical and subtropical regions, home to nearly […]
Environmental monitoring and management with drones
The old saying “a stitch in time saves nine” is pretty apt for environmental monitoring and management. The sooner that we can spot a problem in the environment, the smaller it usually is and the easier it is to fix. When a problem goes unnoticed for a while, it can quickly snowball and become very […]
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 […]
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 […]
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. […]

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. […]
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 […]
