metadata type of 4 products

*EO3 for ARD Landsat Collection 3*

### Used by Products ðŸ”—

### Searchable Fields ðŸ”—

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.

time
datetime-range
Acquisition time range

### Additional Fields ðŸ”—

creation_time
datetime
Time when dataset was created (processed)

crs_raw
string
The raw CRS string as it appears in metadata

dataset_type_id
string
ID of a dataset type

eo_gsd
double
Ground sampling distance of the sensorâ€™s best resolution band
in metres; represents the size (or spatial resolution) of one pixel.

eo_sun_azimuth
double
The azimuth angle of the sun at the moment of acquisition, in degree units measured clockwise from due north

eo_sun_elevation
double
The elevation angle of the sun at the moment of acquisition, in degree units relative to the horizon.

fmask_clear
double
The proportion (from 0 to 100) of the dataset's valid data area that contains clear land pixels according to the Fmask algorithm

fmask_cloud_shadow
double
The proportion (from 0 to 100) of the dataset's valid data area that contains cloud shadow pixels according to the Fmask algorithm

fmask_snow
double
The proportion (from 0 to 100) of the dataset's valid data area that contains clear snow pixels according to the Fmask algorithm
