Imagine a satellite that not only takes pictures of Earth, but can also identify what materials compose each pixel of the image. This is the promise of hyperspectral imaging – a technology giving satellites “super-vision” across hundreds of colors beyond human sight. Hyperspectral sensors capture detailed spectral fingerprints of objects by measuring reflected light in…

Definition and Basic Principles Satellite imagery refers to images of Earth (or other planets) collected by orbiting satellites. These images are a form of remote sensing, meaning the data are acquired from a distance without direct contact. Satellites carry sensors that detect electromagnetic radiation reflected or emitted from the Earth’s surface. Most imaging satellites use passive sensors that rely…

Chad, a vast landlocked nation in Central Africa, has one of the world’s lowest rates of internet connectivity. As of early 2025, only about 13% of Chadians use the internet, compared to a global average around 60% capmad.com. This places Chad near the bottom globally in internet access. The digital infrastructure is underdeveloped, and most…
