YSBAT  Spectral Response Patterns   02-6-07

- Define the term “spectral response pattern”

- Explain the key concept behind remote sensing

- Draw spectral response pattern graphs, labeling the axes correctly

- Draw an idealized spectral response pattern for vegetation

- Identify which wavelengths are most effected by photosynthesis and explain how

- Explain how the spectral response pattern of healthy vegetation would be expected to differ from unhealthy vegetation

- Explain how deciduous forests spectral patterns differ from conifers and why

- Identify which wavelengths are most affected by leaf moisture content, and explain how

- Draw an idealized spectral response pattern for soil, and explain how texture, humus and mineral content each affect that pattern

- Explain why ferric soils are red

- Draw an idealized spectral response pattern for water, and explain how this response pattern may be used to create bathymetric maps

- Explain the difference between a “spectral pattern” and a “spectral signature”

- Define “instantaneous field of view” or “spatial resolution”

- Describe what a “mixed” pixel’s spectral response pattern (of vegetation and soil, or soils and water) might look like

- Define “band of imagery” or “spectral resolution”

- Explain what the pixel values in a satellite image represent (what a low and high number mean), and why they have a particular range
