You might assume that Lizard Island is pristine, but it's not immune from the effects of litter. Unfortunately it was all too easy and fast to collect this haul.

Loving the patterns in this natural rock shelf off Jervis Bay, New South Wales! Any geologist or geomorphologist out there who can shed some light on how they form? Thank you to Graham Doig, UNSW for sharing data.geonadir.com/image-collec... #geology #geomorphology #dronemapping

Kaikōura (NZ) literally means "eat crayfish" (kai = food/eat, kōura = crayfish) in Māori, making it a seafood lover’s paradise! It’s also one of the best places in the world to see sperm whales year-round! Thanks James Driscoll for sharing

🚁 Matrice 4 Enterprise vs. Mavic 3 Enterprise – Which one wins for drone mapping? 🚨 Bottom line: If you’re choosing between the M3E and M4E, the decision comes down to cost vs. capability. We break it all down in our latest blog. Read the full review here: geonadir.com/matrice-4-en...

A review of the Matrice 4 Enterprise (M4E)
We tested the DJI Matrice 4 Enterprise, putting it through its mapping paces and comparing it to the Mavic 3E in capabilities and price.

Important example showing how synthetic aperture radar (SAR) and optical satellite data are complementary. Here are pairs of images used by Reuters to document gravesites in Sudan’s famine-stricken Zamzam camp. www.reuters.com/investigates... Imagery from Umbra (SAR) & Airbus (optical).
Four images showing fresh graves in cemeteries near the Zamzam refugee camp. The left column is two synthetic aperture radar images, which look like grainy black and white photos. On the right are two very high resolution true-color satellite images. Some graves are visible in both synthetic aperture radar and true-color imagery, others are more easily identified in one or the other. The two types combined help provide a more accurate picture of the total number of graves.

☁️Cloud computing at it's best haha :) With most pixels classified at cloud more than 70% of the time at our study site in the Torres Strait, we've had to get creative and use 193 images over two years to build a cloud free Sentinel-2 composite for habitat mapping

All maps are wrong, but some are useful! My reefs of interest were missing from the Autel remote controller mission planner. Thankfully we had other data on hand on GeoNadir that we could use for planning to import!

For 25 years I have been trying to map live coral on the GBR. Now and then I get a step closer. Today was one of those days as we continue to test our latest #GeoAI on @geonadir.bsky.social. No labeling required, working with a single word prompt. Not perfect, many caveats, but ultra cool.
