    75 A new metadata class can now be added to raster maps. We called it semantic labels. Examples of semantic labels are satellite bands (blue, green, red, nir, etc), dataset names in remote sensing products (ndvi, evi, lst, etc), or whatever the user wants to use to identify raster maps. This new feature brings in a series of and advantages. Users can register time series of satellite images and then select which bands or semantic labels to work with, for example, estimate NDVI from a Sentinel 2 time series:
