#sentinel2 — Public Fediverse posts

The Gendox AI Agent is adapting the SeaScope platform for wildfire monitoring.

These Copernicus Sentinel-2 images show the Porto Germeno wildfire on 31 July 2026 at approximately 09:30 UTC.

We hope everyone is safe. Strength and courage to all those working on the ground.

“HIGHLIGHTS:
• Developed a GEE-based global coastline detection framework (S2Coast).
• HWLSentinel-2 serves as a unified and stable indicator for global coastline detection.
• The S2Coast-2023 coastline dataset is generated from annual Sentinel-2 imagery.
• Pixel-level accuracy compared with VHR-based OpenStreetMap coastlines..."

Result of a Principal Component Analysis (PCA) created from combined median composites of Sentinel-1 and Sentinel-2 imagery — somewhere in the Sudanese desert.

This PCA composite brings out contrasts between lithologies, structural domains, drainage patterns, and surface materials, highlighting features that are nearly invisible in standard RGB representations.

And yes — it also happens to look stunning.

Result of a Principal Component Analysis (PCA) based on combined median composites of Sentinel-1 and Sentinel-2 satellite imagery — somewhere in the desert of Sudan.

The PCA highlights contrasts between different lithologies, structural domains, and surface materials, revealing subtle geological features that are hard to distinguish in standard RGB composites.

And yes — it also looks simply beautiful.

Comparison of the median-seasoned NDVI for central Calgary: 2024 vs 2025

Here is a side-by-side look at how the vegetation conditions in central Calgary changed between two years, using median-seasoned NDVI maps derived from Sentinel-2 imagery.

You can clearly see the interannual differences in greenness — especially in parks, riparian zones, and residential areas with large tree cover.
The spatial patterns remain stable, but 2025 shows noticeably higher NDVI in many neighbourhoods due to more favourable moisture conditions.

This is part of my ongoing project on analyzing the vegetation dynamics of Calgary communities: #GreennessOfCalgary

In the distant 2016, when I was a member of an environmental NGO in Kryvyi Rih (Ukraine), I started using satellite Earth Observation data to monitor the condition of large industrial tailings ponds.

At that time, environmental regulations required these storage facilities to be either flooded or at least kept moist to prevent dust storms.
Industrial operators often ignored these rules, leaving huge dry surfaces exposed — which created massive dust pollution affecting nearby communities.

Using Sentinel-2 and Landsat-8 imagery with false-color composites, I developed a simple but effective method to map dry, moist, and water-covered zones of tailings ponds.

Local residents and journalists were absolutely delighted! Industrial companies, on the other hand… reacted very differently 🤣

These maps are from 2016–2017 and show several tailings facilities around #KryvyiRih.

🌿 Greenness of Calgary Communities (Summer 2024)
📎 https://www.datastory.org.ua/greenness-of-calgary-communities-summer-2024/

Last year I published my first attempt to analyze the actual vegetation condition across Calgary and to build a data-driven ranking of its communities based on median summer NDVI. It was my very first experiment in assessing urban greenness at the neighbourhood scale — but the results turned out surprisingly insightful.
Some patterns were expected, while others revealed unexpectedly low vegetation density in places that looked green from the ground.

This exploration later grew into a much larger line of research on Calgary’s greenness, climate resilience, and spatial variability in vegetation health. You can find some results here with thematic hashtag #GreennessOfCalgary

If you're working on urban ecology, remote sensing, or land-cover analysis of Canadian cities — I’d be happy to exchange ideas.

Another remarkable near-equatorial tropical cyclone off the east coast of Africa. TC #Ialy 🌀briefly formed an eye and may have become hurricane strength seen here by #Sentinel2 🛰️ yesterday around the latitude of the Tanzania🇹🇿-Kenya🇰🇪 border #CycloneIaly

Lava fountains are spectacular, but most of the lava falls back into the crater or spatters just a bit around it. During the activity you still get some overflows, that typically cover one or two kilometers.

Outstanding radar image of the #Shiveluch #volcano.
#Radar data is not affected by cloud cover or rain. It can be acquired day or night, and often penetrates snow down to bedrock, unlike optical data (e.g. #Sentinel2, #landsat ).
Acquired on April 17, it shows the immense collapse of the crater, and potentially a growing lava lobe.
Kudos to @RaphaelGrandin and Alina Shevchenko for their work in the area and Capella Space for providing the image.
