Searchable Fields 🔗

cloud_cover double The proportion (from 0 to 100) of the dataset's valid data area that contains cloud pixels. For these ARD products, this value comes from the Fmask algorithm.
dataset_maturity string One of - final|interim|nrt (near real time)
gqa double GQA Circular error probable (90%)
lat double-range Latitude range
lon double-range Longitude range
region_code string Spatial reference code from the provider. For Landsat region_code is a scene path row: '{:03d}{:03d}.format(path,row)' For Sentinel it is MGRS code. In general it is a unique string identifier that datasets covering roughly the same spatial region share.
