A question about Sentinel-2 Views on the Living Atlas. I can't for the life of me work out how to filter by a specific date in ArcPro. At the moment whatever date expression I enter it seems to just return the most recent relatively non-cloudy image. Has anyone else had experience with Sentinel-2 Views?
There is a default definition query on the layer which, as described, shows the most recent and most cloud free imagery available. You can remove the definition query in order to access the full 14 month rolling archive.
In Pro:
Maybe somebody in the Imagery and Remote Sensing space could help?
Note all the most recent ~2 days of imagery never is available in either Sentinel-2 Views or Sentinel-2 Level-2A services (even when removing all def queries/filters and for a tile with confirmed acquisition date), as far as I can make out. If anyone has figured out a way to access, I'd love to know how.
I just checked the currency of the Sentinel-2 Level-2A data I loaded from Living Atlas in to an ArcPro project I am working on today (16 Aug 2023). With no definition query set, the data displayed matches the L2A data collected on 14 Aug 2023. The attached Sentinel2_L2A_14Aug2023.jpg shows 14 Aug 2023 data viewed through https://dataspace.copernicus.eu (top panel) and the Sentinel-2 Level-2A data loaded from Living Atlas (no defQ set) viewed in an ArcPro project. Notice the cloud cover matches in the two panels, confirming the data collected 14 Aug 2023 is available in the Living Atlas dataset two days later on 16 Aug 2023.
If a definition query is set for the Sentinel layer that is based on cloud cover (or some other attribute), most recently collected tiles may not display if they have levels of cloud cover that exceed that specified in the DefQ.
For the exent I am working in today, the Sentinel imagery collected on 27 Jul 2023 has much less cloud cover compared to the imagery collected 14 Aug 2023. To display the 27 Jul 2023 scene I specified a DefQ (using the calendar picker) where AcquisitionDate is after 25 Jul 2023 and AcquisitionDate is before 30Jul 2023 (see Sentinel2_L2A_specificDateRange.jpg attached). I could probably narrow this window down, but what I used gave me access to what I needed.
Thanks, CAEPMAN. I still can’t get day-after or same-day imagery via the Living Atlas service the way I am able to access it (via Copernicus or AWS download process, usually within 5 hours of acquisition(. Our agricultural users need it the day after for harvest and related decisons. Two days is too long to wait, unfortunately.
