HLS Metadata

by waltersdan » Mon May 27, 2024 11:44 am America/New_York

Hello,
Would it be possible, in the future, to include more image metadata in the HLS STAC item properties? Currently, the only metadata are eo:cloud_cover and the acquisition time. The remaining metadata for each image are available through the 'metadata' asset, but this requires a get() call for each image and can be slow for a large query. If the metadata were in the STAC item itself, then when using e.g., stackstack.stack(), all the metadata would be available in an xarray object and fast to access. In particular, it would be useful to have the original product ID which contains the satellite (Landsat-8 vs -9) and relative orbit number.
Thanks!
