SentinelHubStatistical -aggregation_interval options

Hello

I’m trying to use the statistical API requesst and I have question which I didn’t find answer in the documentaion . I wanted to know which values can be inserted in the “aggregation_interval” parameter, I am now using P1D which seems to aggregate by month, but don’t find which string should I use to get the daily average.

aggregation = SentinelHubStatistical.aggregation(

    evalscript=ndvi_evalscript,

    time_interval=yearly_time_interval,

    aggregation_interval='P1D',

    resolution=(10, 10)

)



input_data = SentinelHubStatistical.input_data(

    DataCollection.SENTINEL2_L2A

)

P1D aggregates on daily basis. You can see that in your results, where the interval looks something like

'interval': {'from': '2020-01-14T00:00:00Z', 'to': '2020-01-15T00:00:00Z'}

The aggregation_interval is the duration in ISO 8601 duration format, check here for more details.

Do I understand correctly that P1D means no aggregation in time? In that case the from date is the image acquisition date.

P1D is aggregation on a daily basis. Normally, for Sentinel-2, this would indeed mean “one observation”. However, if you go closer to the poles, or you use some other data, i.e. PlanetScope, P1D might as well be more observations…
