Earth As Art - Earth Resources Observation and Science (EROS) Center, USGS

“In addition to their scientific value, many satellite images are simply intriguing to look at. Satellites capture an incredible variety of views of Earth. See the mesmerizing beauty of river deltas, mountains, and other sandy, salty, and icy landscapes. Some might even remind you of actual famous works of art!...
Earth As Art relies on the interplay of visible and invisible light across the electromagnetic spectrum made possible by satellite sensors….”

remote sensing imagery Rupert Bay, an arm of James Bay, extends into Quebec, Canada. Many rivers carry sediment into the bay and combine with seawater coming in from the tide. A prominent sediment stream extends past Stag Island and a vortex curls off Stag Rock in the middle of the bay. Sediment trails off the islands toward the mainland, indicating the tide was coming in at the time of image acquisition.
remote sensing imagery - One glacier on Russian islands in the Arctic Ocean surprised scientists with its rapid change. After decades of normal, slow movement, a glacier draining Vavilov Ice Cap sprang forward, accelerating rapidly after 2013. This fast movement is extremely rare for cold-based glaciers. In 5 years, the ice tongue doubled in size. In this inverted rendition, land is blue and fractured sea ice appears tan across the top of the image.
remote sensing imagery - Rock folding on a tectonic scale occurred in northwestern Africa. These motley ribbons dancing across the desert in Morocco are folds caused by the prolonged collision of tectonic plates. The long continuous line is Jbel Ouarkziz, a ridge that rises 200–300 meters above the valley floors.

"A series of tutorial videos on how to access the Sentinel Hub APIs in your Copernicus Data Space Ecosystem Jupyter Lab using Python. Learn how to configure your credentials, search and discover Sentinel-2 L2A imagery and how to visualise them afterwards. Lastly, the videos also show you how to create time series analyses derived from the same data." https://www.youtube.com/playlist?list=PLj4KwRQTBlPL3CVwpaBXl3VrO0_V3VX_Q

@ai6yr we are looking forwards to Slovenia, home of Sentinel Hub, becoming a Member a state of European Space Agency in 2024!

I had the pleasure to attend their summerschool last year. They got bought by Planet. Really awesome folks.

There are plenty of Webinars from ESA and EUMETSAT

https://training.eumetsat.int/
https://www.copernicus.eu/en/opportunities/education/copernicus-mooc

ESA really wants to push it (which is awesome) and some summer schools are free (as in tuition, some even fully funded)

I am sure NASA and others have similiar resources.

Possibly some of the last open water on the Yukon River below the Tanana River confluence, found at Kaltag, AK. Product from National Water Center's Synthetic Aperture Radar River Ice Surveillance. Derived from SAR . Image acquisition: 2023-11-16 17:00 UTC.

ICEYE estimates of damage in #Lahaina. (based on ground video, I strongly disagree with their "undamaged" assessment around Banyan Tree Park and the harbor, where 18 bodies were also discovered) "Standing" building is not "undamaged" #Hawaii #satellite #imagery

@ai6yr “Ground truth” always needs to be taken literally, both in sensing and modeling.

geographile,

@ai6yr that's the huge elementary school
