Revealing the unseen: Multispectral and hyperspectral imagery across the electromagnetic spectrum
Satellites play a crucial role in expanding our vision and revealing unseen wonders. By capturing imagery in various wavelengths, including red, green, blue, near-infrared, shortwave infrared, and hyperspectral ranges, satellites enable us to "see" what would otherwise remain invisible to us.
Through spectral analysis, we delve into the diverse wavelengths of the electromagnetic spectrum, ranging from blue (~400 μm) to near-, mid-, and long-range infrared. Each wavelength tells a unique story, providing valuable insights into man-made materials, rock types, minerals, plant species, and much more. These types of imagery, known as multispectral and/or hyperspectral imagery, contain multiple spectral bands, forming a rich tapestry of information.
The more bands we have, the more solutions and answers we can uncover. By venturing beyond the visual perspective and exploring the NIR, SWIR, and TIR bands, we gain access to the hidden spectra of the data. This opens up exciting possibilities, such as species of vegetation identification, mineral mapping, and disturbance monitoring.
