Accessing Landsat 8 Data

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 L8L1C data. For an overview of all API parameters see the API Reference.

Data type identifier: L8L1C

Use L8L1C as the value of the parameter in your API requests. This is mandatory and will ensure you get Landsat 8 data.

Sets the order of overlapping tiles from which the output result is mosaicked. Note that tiles will in most cases come from the same orbit/acquisition. The tiling is done by ESA for easier distribution.

mostRecentselected by default. The pixel will be selected from the tile, which was acquired most recentlyin 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.
leastRecentsimilar to mostRecent but in reverse order
leastCCpixel is selected from tile with the least cloud coverage meta-datanote 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.

Available Bands and Data

Information in this chapter is useful when defining input object in evalscript. Any string listed in the column Name can be an element of the input.bands array in your evalscript.

B01Ultra Blue (443 nm)30m
B02Blue (482 nm)30m
B03Green (561.5 nm)30m
B04Red (654.5 nm)30m
B05Near Infrared (NIR) (865 nm)30m
B06Shortwave Infrared (SWIR) 1 (1608.5 nm)30m
B07Shortwave Infrared (SWIR) 2 (2200.5 nm)30m
B08Panchromatic ( 589.5 nm)15m
B09Cirrus (1373.5 nm)30m
B10Thermal Infrared (TIRS) 1(10895 nm)100m * (30m)
B11Thermal Infrared (TIRS) 2 (12005 nm)100m * (30m)
BQAQuality Assessment band (QA)30m
dataMaskThe mask of data/no data pixels (more).N/A**

*TIRS bands are acquired at 100 meter resolution, but are resampled to 30 meter in delivered data product (source).
**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.

For optical bands, REFLECTANCE is the default and only unit and for brightness temperature bands the default and only unit is KELVIN.

BandUnitSource FormatTypical RangeNotes
Optical bands

REFLECTANCEUINT160 - 0.4Higher values in infrared bands. Reflectance values can easily be above 1.

Catalog API Capabilities

To access Landsat 8 product metadata you need to send search request to our Catalog API. The requested metadata will be returned as JSON formatted response to your request.
