Version 1.6 Release

We're ready to release version 1.6 of Wyvern's data product!

This release focuses on improving cloud masking and tasking which will enable you to more easily identify and mitigate the effects of clouds, haze, and cloud shadows in your imagery.

Notes

• Improved Usable Data Mask:
  • Improved cloud mask
  • Added cloud-shadow mask
  • Added haze mask

Usable data mask with cloud mask.

• Removed 'Cloudy Collection Retasking' parameter from constellation tasking orders. This parameter is no longer required as Standard and Premium tasking orders will automatically include cloud retasking if the imagery does not meet the cloud cover policy.
• Added scale and offset parameters to STAC metadata for each hyperspectral band. The values are 1 and 0 for top-of-atmosphere radiance which means no scaling or offset is applied from the delivered pixel values; however, this allows software that requires scale and offset values to automatically ingest them.

Example scale and offset metadata

{
  "raster:bands": [
    {
      "nodata": -9999,
      "sampling": "area",
      "data_type": "float32",
      "unit": "W·sr-1·m-2·µm-1",
      "scale": 1.0,
      "offset": 0.0
    }
    // ... other bands ...
  ]
}
