Today is #WorldSoilDay so I thought I'd share an animation of Winter Hill in the West Pennine Moors. This illustrates how #Sentinel1 #SAR satellite data can be used to delineate #peatland condition.
Turquoise denotes wetter peatland, drier areas are in brown.
Our research found frozen conditions to better differentiate peatland from other land cover & highlight relative condition. Check it out here

🎓 GeoTech Cohort Sharing
More highlights from the GFP Annual Conference 2025 in Budapest! 🇭🇺🌊
Our GeoTech student Ayesha Tariq joined workshops on improving flood forecasts, risk mapping in data-scarce regions, and integrating Earth Observation with local knowledge for resilience planning.
The conference concluded with a visit to the Kvassay Dam, emphasizing the importance of connecting early warnings with community action.

В понедельник "Известия вузов России. Радиоэлектроника" опубликовали нашу с коллегами статью. Ура!🎉
Основана она на магистерском дипломе, написанном ещё в прошлом году, так что это был долгий путь.
Всё началось с того, что мне в руки попал набор интерференционных фильтров, и на его основе мы сделали многоспектральную камеру. В качестве "мозга" - #raspberrypi 4, а механические детали сделаны путём 3D печати.
