What is spectral differentiation in remote sensing?

Spectral differentiation in remote sensing refers to the ability to detect and differentiate objects or features based on their unique spectral signatures or characteristics. It involves analyzing the reflectance or emission of electromagnetic radiation across different wavelengths to identify and classify different materials or land cover types. By examining the distinctive spectral responses of various substances, remote sensing technology can provide valuable information for applications such as land cover mapping, resource monitoring, and environmental assessment.
