The new layer is based on a JavaScript script by remote sensing expert Pierre Markuse, combining visible red, narrow near-infrared, and short-wave infrared 2 spectral bands to display active fires in white/yellow, burning vegetation in red, and burned areas in dark brown or black. Sentinel-2 satellites provide multi-spectral imaging at resolutions as fine as 10 meters, making the tool useful for real-time wildfire monitoring by anyone. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What new feature did Copernicus Browser add for tracking wildfires? Copernicus Browser added a dedicated wildfires visualization layer for Sentinel-2 imagery that went live on August 4. Clicking the layer over a wildfire location shows active fires in white or yellow, burning vegetation in red, and burned landscape in dark brown or black, making fire extent easier to interpret than the browser's prior 10 default band-combination layers. _Anyone building or evaluating disaster-monitoring tools can follow satellite tooling updates like this on daily.dev._ ### How does Pierre Markuse's wildfire script for Sentinel-2 imagery work? The script combines three spectral bands captured by Sentinel-2's multispectral instrument: the red visible light band, a narrow near-infrared band that highlights differences between healthy and burned vegetation, and the short-wave infrared 2 band, which reveals burned landscape by exposing soil moisture levels. It renders active fires, burning vegetation, and scorched land in distinct colors. _Developers working with multispectral satellite data can track techniques like this on daily.dev._ ## Community take How the wider developer community reacted, aggregated from 1 discussion and 13 comments across hackernews (as of 2026-09-14). **TL;DR:** Commenters are broadly positive about the new wildfire layer, sharing tips on how to enable it and pointing to related tools, while also noting interesting side effects like detecting industrial heat sources and war-zone activity. **Sentiment:** 65% positive · 25% mixed · 10% skeptical **The case for** - The tool is sensitive enough to pick up heat signatures beyond wildfires, which commenters see as a sign it works well. - Several alternative and complementary tools were shared, suggesting the broader ecosystem of free satellite fire-tracking is healthy. **The pushback** - The layer also flags industrial sites like steel plants as 'on fire,' producing false positives that could confuse casual users. - The UI is not immediately intuitive — the configuration dropdown being scrollable is easy to miss. **By community** - hackernews (positive): Mostly enthusiastic, with practical help exchanged on using the tool, plus side discussions about weather imagery APIs and unintended OSINT applications. **Hottest debate:** Whether false positives from industrial heat sources and war-zone activity are a useful feature or a potential source of confusion. **Open questions** - Is there a European equivalent of NOAA's GOES live high-resolution weather imagery with direct JPEG links for scripting? - How frequently does Sentinel-2 update imagery for a given region, and is that cadence sufficient for real-time wildfire response? **Highlights** > It also shows certain industrial areas like steel plants as "on fire". > — [amelius on hackernews · 1 comments](https://news.ycombinator.com/item?id=49221605) > It's also a warzone visualization tool unintentionally. > — [lnenad on hackernews](https://news.ycombinator.com/item?id=49221899) > In case someone wants NASA firms wildfire 7 day vector tiles : http://serveur.cartes.app/pmtiles/MODIS_C6_1_Global_7d.pmtil... > — [maelito on hackernews](https://news.ycombinator.com/item?id=49220762) > Do any European space agencies make live weather imagery available at high resolution? I'm looking for a direct link to JPEGs that update regularly, to use with a cron script to use as desktop wallpaper. I can easily do this for North America using imagery here, for example: https://www.star.nesdis.noaa.gov/GOES/conus.php?sat=G16 (bonus, imagery is Public Domain). This direct link provides an updated image every five minutes, with even higher resolution available if you like: https://cdn.star.nesdis.noaa.gov/GOES19/ABI/CONUS/GEOCOLOR/2... Every time I revisit this idea and look for western Europe, I find nothing. Or, very low resolution, or some clunky, proprietary "viewer" forced on users. Is there really nothing similar for Europe? > — [tombrossman on hackernews · 3 comments](https://news.ycombinator.com/item?id=49222051) **Source threads** - [hackernews](https://news.ycombinator.com/item?id=49220313) · 134 points · 13 comments ## Community discussion Top comments from developers on daily.dev. **@taiwofrancis** · 1 upvotes > This is a great example of technology being genuinely useful. ## Similar posts on daily.dev -
