In late Dec 2019 and Jan 2020, large bushfires devastated areas
in the Adelaide Hills and on Kangaroo Island in South Australia.
To assist in the recovery process, we are mapping specific areas using
high resolution LiDAR, VNIR hyperspectral scanning and high resolution RGB imaging.
There are now also two 3D-interactive views of the Lidar pointcloud - click the image - and make sure you set POTREE to "High Quality".
Zoom in to individual tree size.
To our amazement, we even found two eagles
soaring over the forest. And yes, these are eagles, the lager one has a wingspan of 1.48m.
Check it out yourself in the POTREE animation !
The Fly-Through was generated from the Lidar pointcloud coloured by the RGB-imagery. All data is from the flight - no ground-based data. Download the data from here.
Most data from these flights is available (at no cost) to interested parties.

This project has now lead to a new facility available at ARA for science applications
- a State-of-the-Art Terrestrial Laser Scanner (TLS) Riegl VZ400i.
-
High laser pulse repetition rate of up to 1.2 MHz
-
High speed data acquisition up to 500,000 measurements/sec
-
Wide field of view, 100°x360°
-
Range up to 800 m, accuracy 5 mm
The TLS can be used as a stand-alone sensor
or make a powerful combination with the existing ARA airborne Lidars (ALS).
Some examples can be seen here.
The MAXIM Foundation is a Not-For-Profit organsation based in Cairns.

Mangrove Dieback along the coast of the Gulf of Carpentaria
In Aug/Sep 2017, we mapped the mangrove dieback
that is currently occurring in many areas
along the coastline of the Gulf of Carpentaria
in Far North Queensland and the Northern Territory
Sensors used: Riegl Q680i-S LiDAR

The team
More than 6,000km of flightlines were mapped over 3 weeks yielding >3,000sqkm of covered area.
The project and data capture is described in detail in this document:
The document also contains links to the full data set.
All data are freely available for download.
A collaborative project with funding from: Charles-Darwin University, TropWater/JCU, Queensland Herbarium and ARA; supported by R. Lucas, U of Wales Aberystwyth, UK and Riegl Lasermesstechnik, Austria.
All data will also become available on the TERN/AusCover portal.
LiDAR bathymetry of Ningaloo Reef, NW-Western Australia
We recently flew our topographic and bathymetric Lidars over Ningaloo Reef. We were very fortunate with the weather and water conditions, so we were able to "see" into the water all the way down to more than 13m depth.
The topographic Lidar (a Riegl Q680i-S) was mapping the water surface, giving us an image of the waves crashing into the reef edge, while the bathymetric Lidar (a Riegl VQ820G) gave us a very detailed image of the reef structure below.
Use the slider to uncover the underwater reef structure !

WHAT WE DO
WHO WE ARE
We are an independent certified Not-For-Profit Approved Research Institute (ARI) with strong links into the science networks nationally and internationally.
We have a long-standing solid track record of involvement and leadership in a large number of Australian and international science-based projects where the use of airborne technologies were essential.
HOW WE OPERATE
or
SHARING IS THE KEY
Most of our work is done in collaboration or partnerships with Universities, public entities or Industry.
As an ARI, our policy will continue to keep our work as transparent and traceable as possible manifested through the use of open source software, open and free discussions with collaborators and other specialists in the field about methodologies and procedures, and by making the data collected during science-based projects available to the relevant communities through open data repositories and archives - whenever possible and controlled by appropriate procedures.
We have a policy of sharing our airborne technology, data and expertise - in particular with students, scientists and small groups and businesses such as ours.
To facilitate airborne data capture and/or trials in the context of student projects, small scientific projects and projects in collaboration with other Not-For-Profit entities, we maintain a register of desired locations and types of data on the basis of which we may then propose to combine them to make them feasible.
As our aircraft are based on advanced gliding technology, they have the capability to glide for long distances in the event of an engine failure allowing us to operate safely far out over water and over unlandable areas.
Our airborne systems do not require any airport infrastructure for their operation which makes deployment very flexible.
As we operate two nearly identical airborne platforms, there is the ability to fly a large number of sensors in tandem, or if required, identical sensors simultaneously at different altitudes.
The environmental impact of our research platforms in terms of
- carbon dioxide footprint
- exhaust pollution
-noise pollution
- visual impact
is far smaller than that of any other airborne research platform in operation today.
This has enabled us to operate over the most environmentally sensitive areas, such as flying at low altitudes over the protected coral reefs of the Great Barrier Reef or in the wilderness areas of Southern Tasmania.
