[MQ GIS Lectures @MQGeoInfSys]

I stumbled upon this gem that aligns perfectly with what we'll be covering in our Intro to Remote Sensing Lecture next week! 🌟 Thoughts on how this aligns with our lecture material? Looking forward to discussing it with you all next week! @mqnatsci #RemoteSensing #ENVS2364

[USGS Landsat @USGSLandsat]

The UAE received about 10 in of rain, causing major flooding. This video shows Landsat 8 and 9 images of before and after this event in land/water band combinations, making the water appear purple. Learn about different band combinations with Landsat data: https://t.co/BCuZbFwaA0

Here is a thread of my favourite maps of Africa. Let me know which you like most and give me your best theories for how thel all fit together.

In honor of International Day of Forests, here are two Normalized Difference Vegetation Index (NDVI) Landsat scenes of two different rainforests: The amazon rainforest and the Congo rainforest. Learn more about NDVI Landsat scenes: https://t.co/JRYTCD1oGW

Get ready to meet @CopernicusEU ROSE-L 🛰️

"It's a bit like a car, which at the same time should be small, provide a lot of space and go fast, but with little fuel consumption."

Rose-L, the Copernicus L-band Synthetic Aperture Radar, will help monitor geohazards, flying the same orbit of #Sentinel1.

🎥 Full video premiere this Thursday at 16 CET on @esa YouTube: https://t.co/ZTYf3gXLNd

Evolving barrier islands off the coast of Mississippi and Alabama protect the mainland from the Gulf of Mexico’s waves and weather. 🌊

#Landsat captured these images showing the change in these islands from Nov. 29, 2000 to Dec. 31, 2023.

Largest minority group by province in Italy: 2004 vs 2020.

From Albanian predominance to a Romanian one.

According to the @WMO #StateOfClimate report, in 2021, global mean sea level reached a new record high 🌊
The Maldives are particularly vulnerable to this because most of their land stands less than 1 m above average sea level https://t.co/wncrFCOQgH

By compiling more than 30 years of Landsat data we can see how the Amazon River continually reshapes the landscape. This map shows where raster pixels changed from land to water between 1985-2021 and when they changed based on the red-yellow color ramp. https://t.co/GBPLYALJ0H

[USGS Landsat @USGSLandsat]

Do you remotely study rivers, lakes, or wetlands? The Dynamic Surface Water Extent (DSWE) product might be perfect for you! DSWE provides information about the existence of surface water in Landsat data. 🛰️🌊

17 rivers flow into the Bangweulu Wetlands in Zambia, but only one drains out. Green tendrils randomly sweep through the image, a landscape dominated by various grasslands, open water, and dense Papyrus grass and Phragmites reeds.

With this #Easter egg 🐣 🥚, featuring a partial #Copernicus #Sentinel1 🇪🇺🛰️mosaic of the #EU, we wish a Happy #Easter to all our friends, colleagues, partners, users and followers who celebrate!

This beautiful view is brought to you by the @CopernicusEU #Sentinel2 B satellite. This is Alaska’s Columbia Glacier, one of the most rapidly changing glaciers in the world. You can explore the image in more detail: https://t.co/yyEiDIozjc

There are many cool places to learn about #EarthObservation, but the single place where you can learn the most is... the next #LivingPlanet Symposium #LPS22 😉

This is #Dubai through the years. By processing 7 million images from the @USGSLandsat satellite, collected between 1985 and 2015, you can see how much this 🏙️has grown.

The @CopernicusEU #Sentinel2 mission takes us to the Atacama desert🏜️
At the top of the image, we can see part of #Chile's largest salt flat, the Salar de Atacama. The bright turquoise rectangles and squares visible along the top part of the image are evaporation ponds.

Did you know? Severe droughts have dramatic consequences on forests.

To better understand the threat, ALAB researchers ventured into the California Sierra Nevada, armed with #remotesensing, to assess the forest’s vulnerability to drought. https://t.co/Oae7ynD4Le
