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:
Image Metadata
All imagery data products are delivered with the hyperspectral imagery data stored in a Cloud-Optimized GeoTIFF (COG) format raster file with LZW compression. Standard GeoTIFF tags for both radiometric and geometric parameters are included.
Usable Data Mask
Products are delivered with a usable data mask raster file generated by Wyvern's QA system in Cloud-Optimized GeoTIFF (COG) format with LZW compression and unsigned 8-bit byte (uint8) data type. The usable data mask raster has four bands:
Pixel Quality Mask
Products are delivered with a pixel quality mask raster file generated by Wyvern's QA system in Cloud-Optimized GeoTIFF (COG) format raster file with LZW compression that has unsigned 8-bit byte (uint8) data type. The pixel quality mask raster has the same number of bands as the image data GeoTIFF (i.e. 23-bands for Dragonette-001 and 31-bands for other Dragonette satellites).
STAC Metadata
All imagery data products are delivered with acquisition time, radiometric, geometric, and other various metadata properties delivered in a JavaScript Object Notation (JSON) format ASCII text file that aligns with the SpatioTemporal Asset Catalog (STAC) open geospatial standard.
