Hi ho, hi ho, it’s off to map we go
@sawsharkman.bsky.social

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.

We are up to 5/5 women speakers now!! #SADF2025

4/4 people to take the mic this morn have been women :) #SheMaps

Excited for the start of #SADF25!

oooh look at that vessel! ;)

Make a difference this summer -- Join @cmshintani.bsky.social and me for an internship at @woodwellclimate.bsky.social and contribute to critical research on climate change.

With credit of course!

Omg! Can I use this in my teaching?

Omg that’s HECTIC!! Looks like the drone pulled up ok tho in the end?

All good! Can be a touchy subject when there are so few of us women in the industry :)

Not guys, but thx :)

Oooh love that thank you!

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

Ultimately open source still needs to be paid for. Otherwise we see great things die in the arse because there is no sustainable funding. The silicon valley start up model of free or super cheap products / services doesn’t do any favours - it builds a culture where we don’t want to pay for things.

There is no such thing as free - someone always pays. I also think that the principles of reciprocity are powerful so we can contribute in one area but take advantage from another depending on the situation.

Super interesting topic. VCs will largely close their minds to open source as there is no protectable IP. But that’s shortsighted imo. Impact investors may take a diff view. From a consumer POV I think we need to be more responsible for paying / contributing when we can.

Hello #geospatial community! We're working on getting this account up and running as soon as possible! Stay tuned. 💜

This is truly an amazing funding opportunity. Travel funding for US-based students to attend @giscience-conf.bsky.social in New Zealand! docs.google.com/forms/d/e/1F...

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!

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.

🚁 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.

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.

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.

Understanding multispectral vs RGB for capture and processing | GeoNadir Help Center With an increasing number of multispectral drones, it's important to understand the considerations in capture and processing

DYK that you need to set higher than usual overlap and sidelap parameters when capturing multispectral (and thermal) #dronemapping data? Here's why...

Yes, it really is this easy.

Super talented, they are fabulous!
