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, with 9 optical and 2 thermal bands. These two sensors provide seasonal coverage of the global landmass. We offer access to both Level 1 data from Landsat Collection 1 and 2. The former will be deprecated in the future. Learn more about Level-1 from Landsat Collection 1 here and for Collection 2 here.
|Spatial resolution||15 m for the panchromatic band and 30 m for the rest (the thermal bands is re-sampled from 100 m)|
|Sensor||Operational Land Imager (OLI) with 9 spectral bands and Thermal Infrared Sensor (TIRS) with 2 thermal bands|
|Revisit time||16 days|
|Spatial coverage||Whole globe|
|Data availability||Since February 2013|
|Common usage/purpose||Vegetation monitoring, land use, land cover maps and monitoring of changes.|
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 1 data. For an overview of all API parameters see the API Reference.

Level 1 from Landsat Collections 1 and 2 can be accessed using the identifiers
LOTL1), respectively, as the
value of the
input.data.type parameter in your API requests. This is mandatory and will ensure you get the correct data.
Collection 2 (landsat-ot-l1) is currently in the preview stage and might thus change.
landsat-ot-l1 stands for Landsat OLI-TIRS Level 1.

Sets the upper limit for cloud coverage in percent based on the precomputed cloud coverage estimate for each 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.

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.
|Bands||Unit||Source Format||Typical Range||Notes|

|REFLECTANCE ||UINT16||0 - 0.4||Higher values in infrared bands. Reflectance values can easily be above 1.|
