It is.
curl example is shown in Sentinel Hub docs. With Python an example that retrieves a normalisation factor for S2L1C data is shown in this example .
Outputing the ‘scene’ object should probably get all the info you are after, see scene object description on SH docs.
Hope that helps.
thanks I could make it work correctly, but it seems that the metadata for sentinel2-L2A is empty, finally I ended up using WcsRequest, to get the information
Hi @mauricio.saavedra.n
It works for me, using the following:
evalscript = """
//VERSION=3
function setup() {
return {
input: [{
bands: ["B02", "B03", "B04"],
units: "DN"
}],
output: {
bands: 3,
sampleType: "INT16"
},
mosaicking: Mosaicking.TILE
};
}
function updateOutputMetadata(scenes, inputMetadata, outputMetadata) {
outputMetadata.userData = { "norm_factor": inputMetadata.normalizationFactor,
"scenes": JSON.stringify(scenes)}
}
function evaluatePixel(sample) {
return [sample.B04, sample.B03, sample.B02];
}
"""
request_multitype = SentinelHubRequest(
evalscript=evalscript,
input_data=[
SentinelHubRequest.input_data(
data_collection=DataSource.SENTINEL2_L2A,
time_interval=('2020-06-01', '2020-06-30'),
mosaicking_order='leastCC'
)
],
responses=[
SentinelHubRequest.output_response('default', MimeType.TIFF),
SentinelHubRequest.output_response('userdata', MimeType.JSON)
],
bbox=betsiboka_bbox,
size=betsiboka_size,
config=config
)
multi_data = request_multitype.get_data()[0]
multi_data['userdata.json']['scenes']
gives me this:
Hope this will help.

i am using your script and get all metadata, but the image only return number 0 or nan, you know why?
When i remove “mosaicking: Mosaicking.TILE”, the image return well.
thanks .
I faced same issue. Any update?
Hi @hminhtri19 ,
When using TILE mosaicking the sample object in the evaluatePixel function is an array. You need to specify to which item you want to access, e.g. return [sample[0].B04, sample[0].B03, sample[0].B02]; (see our documentation for more details).
If this does not help, please share your curl command and we will have a look at it.
