Landsat 8 is the most recently launched Landsat satellite (provided by NASA/USGS) and carries the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS) instruments. These two sensors provide seasonal coverage of the global landmass. Landsat 8 Level-2 (from landsat Collection 2) provides global surface reflectance and surface temperature science products. Landsat Level-2 science products are generated from Collection 2 Level-1 inputs that meet the <76 degrees Solar Zenith Angle constraint and include the required auxiliary data inputs to generate a scientifically viable product. Learn more about Level-2 here.

To access data you need to send a POST request to our
process API. The requested data will be returned as the response to your request. Each POST request can be tailored to get you exactly the data you require. To do this requires setting various parameters which depend on the collection you are querying. This chapter will help you understand the parameters for Landsat 8 Level 2 data. For an overview of all API parameters see the API Reference.

LOTL2  as the value of the
input.data.type parameter in your API requests. This is mandatory and will ensure you get Landsat 8 Level 2 data.
The collection is currently in the preview stage and might thus change.
LOTL2 is an acronym for Landsat OLI-TIRS Level 2.

The pixel will be selected from the tile, which was acquired most recently||in case there are more tiles available with the same timestamp (some tiles are processed by many ground stations, some are reprocessed, etc.), the one, which was downloaded from SciHub later will be used.|
|leastRecent||similar to mostRecent but in reverse order|
|leastCC||pixel is selected from tile with the least cloud coverage meta-data||note that "per tile" information is used here, each covering about a 12,000 sq. km area, so this information is only an estimate .|
Sets the upper limit for cloud coverage in percent based on the precomputed cloud coverage estimate for each Sentinel-1 tile as present in the tile metadata. Satellite data will therefore not be retrieved for tiles with a higher cloud coverage estimate. For example, by setting the value to
20, only tiles with at most 20% cloud coverage will be used. Note that this parameter is set per tile and might not be directly applicable to the chosen area of interest.

: dataMask has no source resolution as it is calculated for each output pixel.
The data values for each band in your custom script are presented in the default units as specified here. In case more than one unit is available for a given band, you may optionally set the value of
input.units in your evalscript
setup function to one of the options. Doing so will present data in that unit. The
Source Format specifies how and with what precision the digital numbers from which the unit is derived are encoded. The
Typical Range indicates what values are common for a given band and unit, however outliers can be expected.
