The fire that swept through the Bromo area left a mark readable from space. Using remote sensing data, changes to the area can be observed not only by comparing conditions before and after the event, but also by tracking the pattern of thermal activity over time. Through Piksel, Sentinel-2 imagery and hotspot data from VIIRS (Visible Infrared Imaging Radiometer Suite) are combined to build a picture of where the fire occurred, when activity was detected, and how the landscape changed.

The Barito River near the Kalahien Bridge, South Barito Regency, Central Kalimantan, has shown clear changes throughout the 2026 dry season. Falling water levels have exposed the sandy riverbed and sandbars beneath. The shift became most visible in mid-August, when the water surface appeared far narrower than it had just months before.

Longsoran yang terjadi di Kampung Pondok Balik, Kecamatan Ketol, Kabupaten Aceh Tengah, merupakan fenomena gerakan tanah yang terus berkembang dan menjadi perhatian karena dampaknya terhadap lingkungan serta infrastruktur di sekitarnya. Perubahan bentang lahan yang berlangsung secara progresif telah membentuk area longsoran yang semakin luas dari waktu ke waktu. Untuk memantau perkembangan tersebut, dilakukan analisis menggunakan citra satelit Sentinel-2 yang diakses melalui platform Piksel yang dikembangkan oleh Direktorat Pemetaan Tematik, Badan Informasi Geospasial.
