You are part of team planning a remote sensing mission to determine vegetation health/stress in Oregon. This satellite will have only 2 bands. You have been asked to advocate for one visible-NIR band (somewhere between 400-1100 nm) and one SWIR band (somewhere between 1100-2400 nm), each with a spectral range of 50 nm. With respect to absorption of electromagnetic radiation in the atmosphere and spectral reflectance of healthy vs. stressed vegetation, which do you choose and why?

Ans.
Introduction
We know that the spectral signature of the vegetation has unique spectral reflectance peaks at both the visible and the near infra red region and hence we will be using Visible-NIR Band and its spectral wavelength is somewhere between 400-1100 nm in the spectrum.
