It includes information such as sensor specifications, date and time of capture, etc. + - MD5 File (.md5): This file contains a Message Digest 5 (MD5) checksum. The MD5 checksum is a unique identifier generated from the data itself and can be used to verify data integrity. Any accidental corruption during storage or transmission will result in a mismatch between the calculated MD5 checksum and the one stored in the file. + - Hyperspectral Datacube (.raw): This file stores the raw hyperspectral data. A hyperspectral datacube is a three-dimensional array where each layer represents a two-dimensional image captured at a specific wavelength band. + - Image File (.tiff): This format stores two image representations depending on the data type. For VNIR data, a True Color Composite (TCC) image is generated. This image combines red, green, and blue bands from the hyperspectral datacube, creating a color representation similar to the natural scene. Conversely, SWIR data utilizes a False Color Composite (FCC) image. Here, bands from the datacube are combined, but the chosen bands may not correspond to the typical red, green, and blue channels. It is important to note that both TCC and FCC images are primarily used for quality control purposes. #### Interim Data Product
