Using the sentinelhub module, I am trying to visualize some Sentinel-1 data. However, SentinelHubRequest doesn’t seem to like my inputs:


from sentinelhub import SentinelHubRequest, DataSource

SentinelHubRequest.input_data(data_source=DataSource.SENTINEL1_IW)

This generates a KeyError, despite SENTINEL1_IW being an acceptable DataSource. Substituting SENTINEL2_L2A does not generate a KeyError, so there seems to be something about Sentinel-1 that it doesn’t like.


How can I request Sentinel-1 IW data from the API?

Hi,

You are right about Sentinel-1 not being well supported in SentinelHubRequest. For now, you can bypass this by manually building a dictionary that SentinelHubRequest.input_data method would build:

s1_input_data_dict = {
    "type": "S1GRD",
    "dataFilter": {
        "timeRange": {
            "from": '2020-06-01T00:00:00Z',
            "to": '2020-06-30T00:00:00Z'
        },
        "mosaickingOrder": "mostRecent",
        "acquisitionMode": "IW",
        "polarization": "VV",
        "orbitDirection": "ASCENDING"
    }
}

request = SentinelHubRequest(
    evalscript=evalscript,
    input_data=[
        s1_input_data_dict
    ],
    responses=[
        SentinelHubRequest.output_response('default', MimeType.TIFF),
    ],
    bbox=your_bbox,
    size=image_size,
    config=config
)

The reference on how to build such dictionary is Processing API documentation.

We’ll try to better support Sentinel-1 in SentinelHubRequest in the next iteration.

Thank. I built the dictionary manually and it is working now.
