Filling Out the Imaging Dictionary Classes
The imaging dictionary is a discipline dictionary, which means that its classes will appear in the <Discipline_Area> at the bottom of the <Observation_Area> in observational product labels (and in the <Context_Area>, if appropriate, in non-observational products). The classes in this dictionary provide parameters and processing information specific to image-type data, which includes data produced by imagers, but also instrument like imaging spectrometers.
Begin: 12 January 2017 for version 188.8.131.52
This is the wrapper class for the Imaging Dictionary. It must be used whenever you want or need to include imaging acquisition or processing parameters in your product label. It has four subclasses, listed below, each of which may be omitted or repeated as appropriate for your data product. The subclasses are fairly complex, so each is described on its own page.
This class ties the imaging descriptions following to a specific image-type object described elsewhere in the product label. This class and its attributes are in the core PDS namespace, and so are described here using the standard "pds:" prefix. How you reference them in your product label depends on the conventions you're using for namespace references. If you're not sure what that means, see [Schema Referencing in PDS Labels: Namespace References] elsewhere on this wiki.
Repeat this class once for each image-type object that you want to tie to this <Imaging> class.
If there are any caveats or special circumstances about this reference that you want to note for end-users, this is the place to do it.
This attribute must contain a string that appears in the <local_identifier> attribute of an image-type object elsewhere in this label.
No standard values are defined for this required attribute.
This class contains attributes describing the image itself, including parameters for exposure, filter description, sampling, framing, and so on.
This class contains attributes describing the instrument that obtained the data, including field of view, various mode settings, commanding, and telemetry parameters.
This class contains attributes describing onboard compression.
This class provides a way to document the production and provenance of the image data object specifically (as opposed to the PDS product).
