Hyperspectral images are ultimately analyzed by users for specific applications. Metadata supplied with the images are critical to enable the user to extract full information from the data. An important part of IEEE P4001 Hyperspectral Standard is therefore to define metadata, which will be physics-informed and related to the camera characteristics. With metadata such defined, it will for example be possible for a user to estimate signaldependent noise in the images. Different applications will require different levels of metadata. P4001 therefore defines notional use cases for machine vision, laboratory, and Geospatial Imaging, in order of increasing need for metadata. P4001 will define required and optional metadata for these use cases.
