Metadata

format GeoTIFF instrument platform product_family geomedian

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)
crs_raw string Coordinate reference system field
data_coverage double How much data is in the scene
eo_gsd double The ground sample distance
eo_sun_azimuth double Sun azimuth
eo_sun_elevation double Sun elevation
label string Label
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.
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
sat_orbit_state string The satellite orbit state, either ascending or descending
sat_relative_orbit integer The satellite relative orbit
time datetime-range Acquisition time range
