Searchable fields

cloud_cover double Cloud cover percentage [0, 100]
collection_category string Landsat collection category, such as T1 or T2
creation_time datetime Time when dataset was created (processed)
eo_sun_azimuth double Sun azimuth
eo_sun_elevation double Sun elevation
instrument string Instrument name
lat double-range Latitude range
lon double-range Longitude range
platform string Platform code
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.
rmse double Landsat root mean square error
rmse_x double Landsat root mean square error in X
rmse_y double Landsat root mean square error in Y
time datetime-range Acquisition time range
