A pixel completely filled with vegetation has a reflectance in the red of 0.03, and in the NIR of 0.25. A pixel filled with soil has a reflectance of 0.2 in the red and 0.4 in NIR. What would be the reflectances for a pixel 0.9 filled with vegetation? Calculate the NDVI and VI indices for this mixed pixel.
