Spectral Bands& Wavelengths
Under DevelopmentDetailed specification of the optical electromagnetic wavelengths captured by spaceborne multispectral scanners.
Optical Remote Sensing Wavelengths
Spaceborne optical sensors split electromagnetic energy into specific ranges called bands. By comparing reflectance differences across absorption bands (like Red) and reflection bands (like NIR), we calculate the health, moisture, and composition of surface features.
