RU interested in using #photogrammetry software to pre-process #dronemapping data, but unsure which package to choose? New paper alert! We take out the guesswork & compare @pix4d @SimActiveInc @AgisoftLimited and @OpenDroneMap. You're welcome :) @joan_lyq

Not sure if this happened to anyone before?
Need some help pls :) Teaching my #remotesensing class with #EarthEngine and several students find it totally locking up. I think it thinks they are commercial and have reached a limit. Urgently need to overcome this. Ideas? @Earthobservation @googledevs

Hot of the press! Newly published research using #drone mapping and #AI to count giant clams on the Great Barrier Reef. This is the work of @jcu masters student Olivier Decitre. https://t.co/635OHDu28V

If you don't fancy making friends with the local wildlife, perhaps it's time to consider drone mapping!

For those of you wondering what's happening on the reef this year, please have a read. Our recent quantitative analysis of North Point at Lizard Island is referred to in this article. This is a global issue with coral reefs this year. #bleaching

Analysis of high-resolution drone imagery concludes 97% of corals died at a Lizard Island reef between March and June this year

And that’s a wrap! After 37 km of ROV surveys, 24 km of BlueBoat surveys, and 189 DNA tissue samples, this trip is over. Thanks to a great team! @MEG_MQ @mqnatsci @MQSciEng @sawsharkman @_krisfish @joan_lyq @Patrick__Burke

Finger crossed for golden weather like this!
Here we go again. Fifth field trip for me so far this year. Back up to Lizard Island and beyond. Thanks for the funding GBRF! @mqnatsci @va_gilliland @MQSciEng @MEG_MQ @sawsharkman @_krisfish @joan_lyq @AnnabellKlinke

There's no shortage of applications of drone mapping in marine and coastal environments. Here are some of our favourites! Visit our blog for stories about each of them https://t.co/QZY184Lyqk

Wondering if it work the same way if combine this with drone data @GeoNadirAu @DrKJoyce
It's possible to MASSIVELY increase the resolution of nightlights data. And no—this doesn’t use generative AI. Here’s what you need to know about it:

Process your #dronemapping orthomosaics and DEMs then get right into integrating with your field and other spatial data. All in one place on #GeoNadir. https://t.co/62IeuodjM2

Finger crossed for minimal wind ahead! @GeoNadirAu
Stoked to be back on Kalinda for more #seacukescience! Going to conduct ROV and drone surveys from Townsville to Cairns over the next two weeks, fingers crossed for some nice weather @GBRFoundation @MEG_MQ @UON_research @jcu
