Description Value Slots See Also Examples

General class that holds basic information about an image. Usually used when working with mosaics, as in this case the image is not read/loaded to R until is processed (e.g. by running a mosaic_sam process). Currently, the only function that returns an object of this class is he mosaic_info function. The object can by used later to read/load to R a single mosaic chuck using the mosaic_chunk function, or to process the whole mosaic image by calling the mosaic_sam function.

The class Tile contains the "Spectral_info" class. By this means, an object of class Tile holds the same information about the reading, and an extra slot called "Spectra" that holds the actual readings.
