Layer stacking is a process for combining multiple images into a single image. The image stack is used to build a ‘new’ multiple band file from the georeferenced images of various pixel sizes, extents, projections. The image bands must be resampled and reprojected to a common spatial grid. The layer stacking is used for example to combine spectral bands from a Landsat, Sentinel-2 data and SRTM DEM into one multi-dimensional file. The process of layer stacking increases the size of the final stacked image, which may have consequences that increase the processing time of operations performed on the stacked image.
