New
Length & width added to STAC metadata
Two new fields have been added to the STAC catalog metadata in the properties object:
-
capella:image_length
-
capella:image_width
These new fields represent the length and width of the image product using the WGS84 ellipsoid projection with no terrain correction.
Updates are also reflected in the SAR Imagery Products Format Specification.
Improved
STAC ID Timestamps
All newly generated STAC IDs for imagery products will now contain the collect duration as the start / stop time instead of the integration start / time previously. This will make STAC ID naming more consistent for all products related to a collect.
This change will not impact any existing STAC IDs. Integration time used for the product creation will continue to be noted in the extended metadata.
