The Sentinel 2 satellite records reflectance in 12 wavelength bands, but the file you have been provided
Question:
The Sentinel 2 satellite records reflectance in 12 wavelength bands, but the file you have been provided
only contains four of them. Using research and citing your sources appropriately, explain why these 4
bands have been chosen for use in imagery based vegetation analysis. (2 marks)
2. Based on the brightness values in the Sentinel imagery you have been provided and the date on which
it was collected (October 3rd, 2023), decide what landcover is present at locations A and B. Justify your
answers by referring to specific brightness values you observed, and based on what you know about
the reflectance of different targets, sketch a spectral curve for each location. (5 marks)
3. How would the spectral curve at location B vary through the course of a year? Sketch at least two extra
spectral curves, in addition to the one you drew for Question 2, to support your answer. (3 marks)
