21.01.2022 Spectral analysis of fuel flammability in an area around a destroyed residential property near Gumeracha in the Adelaide Hills. The right panel shows the burn intensity/vegetation health via a colour-infrared image (healthy vegetation shown in red), while the left panel shows the derived residual flammability. Black, yellow and green show low flammability it’s already burnt, in this case while blue and red show high flammability due largely to low water content. Note that the unburnt dry grass is the most highly flammable fuel in the scene, followed by the blue-classified unburnt trees. Data collected with the Eagle 2 VNIR hyperspectral linescanner on 8th January 2020.

20.01.2022 Spectral imaging shows regrowth on Kangaroo Island Only three months after the fires, many areas were already showing significant new growth. In these comparison images we see the changes from February to April. The colour-infrared images on the right show healthy foliage as bright red. https://jorg688.wixsite.com/vc1-hyper-0206-0413... https://jorg688.wixsite.com/vc1-rgb-0206-0413

14.01.2022 We've just put together some of the data and imagery from the recently burnt timber plantation areas on Kangaroo Island as a five-minute video. All of the presented data is captured from ARA's research aircraft VH-OBS without ground survey, and all lidar points are located to survey-grade accuracy. https://vimeo.com/449896293

11.01.2022 ARA has been developing a new camera installation, aimed at ultra-high resolution aerial photography in RGB and near-infrared. We're now able to achieve a ~5mm pixel size, across a ~100m swath while flying at our normal survey speed of 70 knots. This is a revolutionary advance in resolution from a manned platform capable of covering large areas. Of course we can carry it with lidar, hyperspectral and other sensors at the sanme time - looking forward to new applications coming from this. The sample airborne image is cropped from one of about 4000 images we collected over saltmarsh on Friday and shows the detail now resolvable.

09.01.2022 Cudlee Creek fire regrowth - hyperspectral imagery Last week we collected more data over the Adelaide Hills and Kangaroo Creek firegrounds, with specialised equipment (lidar and hyperspectral imagers) to accurately record the regrowth some nine months and a winter after the fires Here is an image showing part of Wednesday's flight track over the Cudlee Creek area, and some of (very preliminary) hyperspectral results showing regrowth in the region of Bushland Park, a few kilometres NE of Lobethal. As with other colour-infrared images we've posted, healthy vegetation shows as red. We can already see that farmland and open country has "greened up" nicely with fresh grass, while regrowth in the burnt native forest is somewhat variable, depending on the severity of the burn.

08.01.2022 A rather significant paper is now available on the work we reported on a few weeks back, on the submerged indigenous site we studied off of the north west coast of Western Australia. https://www.openquaternary.com/articles/10.5334/oq.81/

08.01.2022 ARA gets a mention in Parliament Last week Federal MP Rebekha Sharkie (Centre Alliance), member for Mayo, the electorate covering the areas ARA has been conducting its "imaging for bushfire recovery" project, spent an hour with us at Parafield. Yesterday she gave a very supportive message of support to the Australian Parliament. Thanks Rebekha! https://youtu.be/S3bee_GUA0U

07.01.2022 ARA work helps reveal Aboriginal archaeological sites Our use of bathymetric lidar shows ancient human made structures underwater off the north west Australian coast. https://www.abc.net.au//aboriginal-underwater-sit/12391858

03.01.2022 We've just put up a short slideshow describing the data - coverage and data types - collected for the "Bushfire Imaging for Recovery" project over Kangaroo Island and the Adelaide Hills. http://www.airborneresearch.com.au//Fires20/Fires2020.html

03.01.2022 Thanks, Cath L. Conway for this beautiful photo of VH-OBS yesterday evening, resting in the ARA hangar after its return from a flight over the Adelaide Hills collecting data to record the recovery of vegetation after last summer's bushfires. Today we're doing more of that work, over Kangaroo Island, with the flight plan as shown in the second image.

02.01.2022 More results from the ultrahigh resolution camera system The first image shows a salt pond where we're involved with a study measuring biosequestration of carbon into salt marsh vegetation. This image is taken with our conventional aerial photography system. The small red rectangle shows the area covered by the second image, which shows the resolution of that data capture (to be fair, we can get higher resolution with this older system than shown here, but nothing approching ...the new). The third image is the same area as the second, but with the new camera system, again with a red rectangle showing the area covered by the fourth. The new camera system let us cover the whole pond at the ultrahigh resolution in under an hour.

01.01.2022 The Southern Ocean Lodge, on the south coast of Kangaroo Island near Remarkable Rocks, offered luxury tourist accommodation in a spectacular setting. It was badly damaged in the bushfires in January, as can be seen in this RGB orthomosaic captured by ARA earlier this week, on Easter Monday, approximately three months after the fires.

01.01.2022 Adelaide's new Northern Connector expressway opened to traffic on the weekend. ARA has been doing regular lidar and imagery captures of the area during the construction, and here's the newly opened road as seen yesterday morning.
