Version L2A 2.0 Release
· 2 min read
We've released our Level-2A surface reflectance processing level! This will allow users of Wyvern data to access atmospherically corrected surface reflectance imagery so they can perform hyperspectral analysis faster and without additional tools.
Notes

- New processing level (L2A) delivers atmospherically corrected surface reflectance data. See Processing Levels for details.

note
If you use the filename in your workflows, you may need to update your processes. Our recommendation is to use the STAC JSON metadata file to identify any information you're using. This will allow you to avoid disruption during this update.
