Product Delivery

All imagery data products are delivered as a single ZIP file bundle that contains all imagery data and metadata files packaged together for each individual HSI data product. The name of the ZIP archive file is Wyvern's globally unique identifier (GUID) and processing level for the tasking order imaging collection attempt that generated the resulting imagery data product. The ZIP archive file for any given HSI data product contains the following files:

  • Folder named by GUID and processing level containing all of the imagery data product files
    • Format: <guid>_<processing_level>
      • e.g. 108f5a68-e949-4de7-929c-2d7ef960eba0_l2a
    • STAC Catalog File (This file is a STAC catalog file for a catalog with a single item. The path to that item's STAC JSON file can be located in the list of links.)
  • Subfolder named by File Naming Convention containing the following files:
    • Hyperspectral Imagery Data Raster TIFF File
    • STAC Metadata Text JSON File
    • Usable Data Mask Raster TIFF File (includes a cloud mask band)
    • Pixel Quality Mask Raster TIFF File
    • Preview Image PNG File (full resolution RGB colour representation)
    • Thumbnail Image PNG File (8x downsampled of the Preview Image)

Naming Convention​

The data & metadata files delivered for any given imagery data product have a consistent naming convention that aligns with the following file naming pattern:

wyvern_<platform_name>_<capture_date_time>_<collection_id>_<processing_level>_<auxiliary_file_type>.<file_extension>

where:

  • <platform_name> is one of the satellites in the Dragonette constellation
  • <capture_date_time> is acquisition time in UTC format [YYYY][MM][DD]T[hh][mm][ss]
  • <collection_id> is the first 8 characters of the globally unique identifier
  • <processing_level> is the processing level of the data product. Possible values are:
    • l1b: Radiometrically calibrated and geometrically corrected data to top-of-atmosphere radiance units
    • l2a: Surface reflectance data that has been atmospherically corrected
  • <auxiliary_file_type> is auxiliary delivery files such as 'preview', 'thumbnail', 'data_mask'
  • <file_extension> is common format file extensions (e.g., '.tiff', '.json', '.png')
