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.

🏙️ The Hellish Trade Zones
(Ukrainian: “Торговельні пекельні зони”)

An older piece from 2017 — but still relevant today.
Using Landsat-8 thermal imagery, I explored how urban heat islands form in large commercial and industrial areas completely devoid of vegetation.

These “hellish trade zones” show surface temperatures exceeding 45–50 °C, while nearby shelterbelts and green spaces remain much cooler.
The visual storytelling approach — combining satellite data, maps, and simple explanations — helped raise public awareness about urban greening and environmental health in my city.

📍 Location: Kryvyi Rih, Ukraine
🛰️ Data: Landsat-8 (July 15, 2016), thermal band 10 + NDVI

#Minimal for today's #30DayMapChallenge

I think this might be my favourite so far.

Terminus retreat at Salliarutsip Sermia*, a tidewater glacier in West #Greenland, between 2000 and 2025.

Termini quickly digitized in #QGIS from #Landsat 7 and 8 scenes acquired on 26/8/2000 and 23/8/2025. Distance measured along fjord (roughly along centreline, y'know).

Finishing touches in #inkscape

*because #Jakobshavn Isbræ needs to learn to share the spotlight.

Landsat & GIS: Khi dữ liệu lên ngôi trong nông nghiệp năm 2025

Năm 2025, nông nghiệp không chỉ dựa vào kinh nghiệm mà dựa trên dữ liệu vệ tinh và bản đồ số. Sự kết hợp giữa Landsat, GIS và nông nghiệp chính xác đang giúp nông dân quản lý từng mét vuông đất, tiết kiệm 40% chi phí và tăng năng suất bền vững.
