This integration is done through the calculation of metrics that describe the behavior of each pixel in the year, such as median values, minimum, maximum, amplitude of variation, among others. Additionally, for each annual mosaic, spectral indices and fractions are calculated. Each of these metrics and indices is stored in the mosaic as a layer or band.
