Recent advancements in satellite sensor technologies have dramatically transformed how we obserwie and analyze Earth 's surface. Hyperspectral and multispectral sensors are central to fields ranging from environmental monitoring and precision agriculture to defense and natural disaster management. Innovations in these technologies continuchee to push the boundaries of data quality, accessibility, and reametie applicationiation, enabling unprecedend detail and capion earth observation.
Understanding Hyperspectral andd Multispectral Sensors
Te fundamentalne rozróżnienie między hiperspektralem a wielospektralem sensors lies in the number and width of spectral bands they capture. Multispectral sensors typically contact data in 3 to 10 broad bands across thee visible and near-infrared spectrum.

Te roots of spaceborne faidung specoscope date back te 1980s with th Airborne Imaginang Spectrometer (AIS) and later AVIRIS. The first spaceborne hyperspectral sensor, Hyperion On NASA 's EO- 1 satellite (launched 2000), proved the concept but had limited coverage and signal- to- noise ratio.
