Additional Request Parameters

Sentinel-2 WMS/WMTS/WFS/WCS services support many custom parameters which affect the generation of the service responses. In the following table, all the available custom parameters, such as preview modes, are listed. All these parameters are optional.

For the examples on how to use them, see this documentation.

Note that atmospheric correction is not a parameter anymore, as we now only support L2A atmospheric correction. Read more about it here.

Custom parameter Info Default value Valid value range Available for

MAXCC

The maximum allowable cloud coverage in percent. Cloud coverage is a product average and not viewport accurate hence images may have more cloud cover than specified here.

 100.0 0.0 - 100.0 WMS/WMTS/WFS/WCS (when REQUEST = "GetMap", "GetTile", "GetCoverage", "GetFeature", "GetFeatureInfo" or "GetIndex")

PRIORITY

The priority by which to select and sort the overlapping valid tiles from which the output result is made. For example, using mostRecent will place newer tiles over older ones therefore showing the latest image possible. Using leastCC will place the least cloudy tiles available on top.

 mostRecent mostRecent, leastRecent, leastCC, leastTimeDifference, maximumViewingElevation WMS/WMTS/WFS/WCS (when REQUEST = "GetMap", "GetTile", "GetCoverage", "GetFeature", "GetFeatureInfo" or "GetIndex")

EVALSCRIPT

This parameter allows for a custom evaluation script or formula specifying how the output image will be generated from the input bands. See Custom evaluation script usage for details.

EVALSCRIPT parameter has to be BASE64 encoded before it is passed to the service.

     WMS/WMTS/WCS (when REQUEST = "GetMap", "GetTile" or "GetCoverage")

EVALSCRIPTURL

This parameter allows for a custom evaluation script or formula to be passed as an URL parameter, where the script itself is located (it should be on HTTPS).

     WMS/WMTS/WCS (when REQUEST = "GetMap", "GetTile" or "GetCoverage")

PREVIEW

See Preview modes for details.

 0 0, 1, 2 WMS/WMTS/WCS (when REQUEST = "GetMap", "GetTile" or "GetCoverage")

GEOMETRY

Outputs imagery only within the given geometry and cropped to the geometry's minimum bounding box.

   one WKT string, one WKB hex string, or a list of coordinate pairs representing a polygon (pairs separated by semicolons, components by comma, i.e. 1 1, 2 2;...) Coordinates should be specified using the CRS of the request (i.e. same CRS as BBOX). WMS/WMTS/WCS (when REQUEST = "GetMap", "GetTile" or "GetCoverage")

QUALITY

Used only when requesting JPEGs.

 90 0 - 100; where 0 is the lowest and 100 the highest quality WMS/WMTS/WCS (when REQUEST = "GetMap", "GetTile" or "GetCoverage")

UPSAMPLING

Sets the image upsampling method. Used when the requested resolution is higher than the source resolution.

 NEAREST NEAREST, BILINEAR, BICUBIC WMS/WMTS/WCS (when REQUEST = "GetMap", "GetTile" or "GetCoverage")

DOWNSAMPLING

Sets the image downsampling method. Used when the requested resolution is lower than the source resolution.

 NEAREST NEAREST, BILINEAR, BICUBIC, BOX WMS/WMTS/WCS (when REQUEST = "GetMap", "GetTile" or "GetCoverage")

WARNINGS

Enables or disables the display of in-image warnings, like "No data available for the specified area".

 YES YES, NO WMS/WMTS/WCS (when REQUEST = "GetMap", "GetTile" or "GetCoverage")
