Love this new tool! Always used the LandSat spectral bands graphic in teaching. Now I can make my own easily.

[ARCHIVED - NASA Landsat @NASA_Landsat]

Our new Spectral Band Comparison tool is here! 📊

Dynamically compare spectral bands from different Earth-observing instruments across the electromagnetic spectrum, then easily output and share your custom graphic.

A new paper out that takes a look at sustainability within New Zealand's aerospace sector!

[A tiny contribution from me, all credit to the amazing team led by @drpriaero ].

🏴󠁧󠁢󠁳󠁣󠁴󠁿 Hello Shetland Islands!

☹️ You were too rainy and windy to fly our drones

30 mph winds and sideways rain

But silver lining, thank you to the locals who embraced us into the pub to hide from the rain

[Dr Imogen Napper @Imogennapper]

🏴󠁧󠁢󠁳󠁣󠁴󠁿 Our first stop in Scotland is Iona

Iona is a tiny island off the southwest coast of Mull in the Inner Hebrides and full of wildlife

I learnt here that sheep eat seaweed?!

[Dr Imogen Napper @Imogennapper]

🇮🇪 The weather lifted and sun shone on us for our fieldwork stop in Cork!

We are testing how common litter items look under different conditions with the drone

Importantly, finishing off the day with our first Beamish!

Heading back to sea and analysing data with ocean views

Satellites have a unique ability to observe geopolitical conflicts & provide evidence of what is actually happening in the midst of unreliable political claims 🛰️

Thread of recent examples from the ongoing Israel-Palestine conflict 🧵[1/n]

@mfordNZ @MMEG_UoA Very much so! Please do drop me an email to connect! :)

[Katarzyna Sila-Nowicka @KatarzynaSila]

It is a very proud moment when student you supervise makes it to BBC :) Well done Jaxon and the team.@AucklandUni @EnvUoA

@mlangsdale1 Hehe amazing! I would prefer mean seal level to be fair.

PhD project alert! If you’re keen to apply your budding pattern recognition and data processing skills to a marine puzzle, this might be the perfect project for you:

Very excited by the possibilties in this!

The updated #LandsatNext specs are wild!🤯

🌈 26 total spectral bands, including #Landsat 8/9 and #Sentinel2 compatible bands
🌳10 brand new application-specific bands
🔥 5 thermal IR bands!
📏10-60 m resolution (including 10 m SWIR!)
⏱️6 day revisit

Introducing Hydro -- A Foundation Model for Water in Satellite Imagery.

There are many foundation models for remote sensing but nearly all of them focus on imagery of land. The earth is made of ~71% water. ML 4 Water needs some more love and attention.

[Thermal Remote Sensing Special Interest Group @thermal_sig]

🔥 The latest episode of the Thermal Lens is out! 🔥

In this episode, @mlangsdale1 chats to us about directionality in Land Surface Temperature (LST) and the joint ESA-NASA campaign she helped run in 2023 to understand directionality better!

An absolute pleasure to host @DLR_en today with @nzspacegovt. Here, Dr Anke Pagels-Kerp presenting an overview of DLR research

[Tom Dowling @TPFDowling]

Excellent example of teaching the latest in methods!

Helping a student detect central-pivot irrigation farms from a Landsat NDVI image. This was done in just 1 minute using the Segment Geospatial #Python package in Colab https://t.co/HlgaKeYmW3. Check the tutorials by @giswqs at https://t.co/CyVAGBzzw9

@James_WE_Smith Fantastic map! Do you have the source/a hi-res version of it I could use in my teaching?

[Dr Robbi Bishop-Taylor 🦋 @SatelliteSci]

Occasionally I see a paper that feels like some kind of forbidden dark magic...🧙

Almar et al. 2024 used tiny time delays between #Sentinel2's spectral bands to model ocean waves... then used those waves to predict water depth/bathymetry!🛰️🌊🤯

What happens when a historic year of rainfall dumps a bunch of freshwater into the ocean next to a western boundary current?
In @NatureComms today, @moninya, @mphemming, Tim Ingleton and I look at the impact of the 2022 East Australian floods on the ocean
