    Description

      1. Implements a new SQL expression for GeoTiff images. Expression name: RS_AppendNormalizedDifference. This transformation calculates the normalized difference index between two bands and appends the index as a new band in the array of all bands. This transformation is used by deep learning practitioners to enhance the features of Raster images.

      2. Updates the raster notebook in the binder to include the improvements made for version 1.2.1.
