Duplicate data for Sentinel-1

Hi, I’m search for Sentiel-1 data in Copernicus Open Access Hub, I find two products with same timespan and same cover but different identifier name. Are they different in some ways or just duplicate data? S1A_IW_SLC__1SDV_20220110T111909_20220110T111936_041398_04EC19_BFDA S1A_IW_SLC__1SDV_20220110T111909_20220110T111936_041398_04EC19_8478

Some Sentinel-2 L2A images missing

Hi, I am wondering why some of the images that are available as L1C are not available as L2A. For example tile 34VFN has 23 images for August 2017 as L1C, but only 8 images as L2A. Is it possible to access those missing images somehow? Thank you, Joona

Missing data in Sentinel 1 archive?

I recently ordered some Sentinel 1 images using the batch processing API and it appears there is a small strip where there were no available images between 2021-05-15 and 2021-07-08. There were images available for this area for the same period in 2020. The image is a screenshot from the EO browser showing the available images for a large area in the United States. There are images available starting in the southern US that appear to be in the same orbit. Is it possible that no images were collected here? Or were they collected and not added to the S3 archive? Any suggestions for tracing to the root cause are appreciated!

404 error when starting batch request

Hello, I tried to start a batch request at around 0920am GMT but got a 404 error: Failed to download from:\nhttps://services.sentinel-hub.com/api/v1/batch/process/<id>/start\nwith HTTPError:\n404 Client Error: Not Found for url: https://services.sentinel-hub.com/api/v1/batch/process/<id>/start\nServer response: \"{\"status\": 404, \"reason\": \"Not Found\", \"message\": \"Not Found\", \"code\": \"COMMON_NOT_FOUND\"}\"", After a few minutes I made another batch request for the exact same area and it succeeded. 404 error is not mentioned in the API reference here (API Reference). Does anyone know what caused the error above? Was the batch api down for some reason, if so how can we check for this? Thanks in advance.

Sentinel 1 productInfo.json and metadata.xml in product root

Hey Sentinel folks, I’m starting to catalog the Sentinel 1 products and noticed that the productInfo.json is an empty file and metadata.xml are not present in the product root dir. Those 2 files we used to gather metadata and populate our catalog. We also used the product GML files for geometry info. For example in this product path, it has an empty productInfo.json and missing metadata.xml file, what would be the best files to parse to grab the necessary metadata to catalog? s3://sentinel-s1-l1c/GRD/2018/11/15/IW/DV/S1B_IW_GRDH_1SDV_20181115T170549_20181115T170614_013618_019365_8C97

Requests, length and height calculation

Hello, and have a good time. I have come across a case in Sentinel Hub. I would appreciate it if you could guide me in this case. Because the cost of each request depends on the length and width of the output image, on the other hand, depending on the size of the polygon, the quality of the output image cannot be defined as a fixed number. How can I calculate the length and width of the input polygon? By the way, I obtained the length and width of the area in degrees using the bbox information, but when I divide by 0.00009, the obtained numbers are different from the length and width numbers of the request builder, and my output image is stretched as well.

Additional Question on No-Data Labels

I have been moving forward on my testing but I keep returning to a question that I cant answer. I may just be the one confused here but I am going to try and reword my question. Although I think I may be close to the solution based previous responses. – So, when using a convolutional neural network (CNN) it is my understanding that its not possible to discard/ignore some pixels since those would leave behind holes. This may be dealt with by eo-learn I am not sure. If we include NO_DATA labeled pixels then that will potentially create training problems in the CNN because it would learn to associate pixel values to a label which is not actually a proper label. I see you say that these pixels are disregarded and not used for training/testing, but I dont understand if this creates some sort of issue. In my code we have a lot of pixels with no-data labels and we are basically trying to come up with the best way to deal with them. This is where we got confused about NaN values vs No-data lab

Problem with dowloading EOPatches with eo-learn

Hello to all. For a long time I have been running the code from the Slovenia example without issue. But for quite a while now, I’ve been seeing endless DEBUG errors without being able to download. I have tried reducing my study area and interval time to no avail. Can you help me to solve this problem ?

GeoTiff from EoPatch

Hi, new user to sentinel-hub here. Just wondering what the best way to extract a eopatch feature to tiff is. My array is shaped: GVMI: numpy.ndarray(shape=(32, 1057, 1860, 1), dtype=float32) and I want to iterate though all 32 time slices to produce tiffs I tried ExportToTiff from eolearn-io with no luck (should I be using rasterio?) for x in range(1, 1, 32): _ _ ExportToTiff(aoi_1.data['GVMI],folder=aoiDir2,band_indices=[0];date_indices=[x]) Probably messing something simple up somewhere. Any suggestions would be great. Thanks kurt

Point data what format and what coordinate system etc

Is it possible to upload a file of points and get data from sentinel 2 for these points on every date when they are clear of cloud (or just zeros where there is cloud). We have data recorders at a network of points and want to match what the satellite says to what our ground based recorders and models say.

Detecting trends on NDVI time-series with Statistical API

Hi everyone, I’m looking to make a function using the NDVI from S2, in order to get a very simple kind of harvest monitoring, where I would like to translate the NDVI values into information, such as, which state is the vegetation at (greening, browning). In the end, the user will have an idea of NDVI trending, in order to know if harvest period is coming, for example. For now I’m using the max ndvi function present in the custom scripts repository for the last 2/ months, aggregated in 15 days - does anyone has any suggestion on how to integrate such function on the script? Would this be possible on statistical api? Thanks in advance! Base script: curl -X POST https://services.sentinel-hub.com/api/v1/statistics -H 'Content-Type: application/json' -d '{ "input": { "bounds": { "bbox": [ 35.3190435045249, -5.448226300909312, 35.323560495475114, -5.443729699090689 ] }, "data": [ { "dataFilter": {}, "type":

Is support email still monitored?

My requests have started failing due to quota, meaning my app is no longer functioning. When I log in to the Web site, I get the warning: Warning: your account has been temporary throttled due to usage exceeding configured volume of processing units. In case of monthly quotas the account will be re-activated at the beginning of the next month. Upgrade your account or contact support@sentinel-hub.com if you feel something is wrong with the settings. More information in Billing section. I recently renewed my yearly (not monthly) subscription so there’s no way I’m over my yearly quota. Perhaps my subscription somehow reset to monthly. As directed by the warning message, I have contacted support@sentinel-hub.com twice over the past two weeks about this issue and gotten no response. Is that email address still monitored, or is there a new one to use? —Andrew

Planetscope surface reflectance product

Dear Sentinelhub team, I wish you a Happy New year! Currently working with Planetscope data, the ingestion is working very well using the productBundle ‘analytic’ (top of atmosphere). However, I wish I could download the surface reflectance product and when I order the query using the product bundle “analytic_sr” or “analytic_sr_udm2”, I get the following error message “requests.exceptions.HTTPError: 400 Client Error: Bad Request for url: https://services.sentinel-hub.com/api/v1/dataimport/orders”. Should we change the url if we are using surface reflectance products? Many thanks and have a great day, Johann

Using the new Copernicus EO-Browser -Open acess to full fraime Sentinel-2 data

For the preparation of a training course organized by ESA Academy, I need full frames Sentinel-2 data. With the new Copernicus catalogue I got with several trials just Network Error messages and once also a different error message. How can I make it working? With the old catalogue I never had problems.

BYOC with CREODIAS

Hello, I am very interested to use the BYOC to ingest my own small satellite (EO) data. However, although I think I follow all the steps: Create a bucket in Creodias SW3_1 Set permissions as described in: https://documentation.dataspace.copernicus.eu/APIs/SentinelHub/Byoc.html Upload a Cloud Geo Tif When I am creating a collection I am not able to ingest my data. I alwasy get the following message: Unexpected error occurred when tried to access the storage (status code = 404). I guess that my bucket is not visible by sentinelhub. Best Regards, David

Sentinel 2 product upgrade integration

Recently ESA announced processing software upgrade for sentinel 2 imageryAnnouncement Link Some snippets from the announcement Data produced by the updated Processing Baseline 04.00 is expected to be available at the Copernicus Australasia Regional Data Hub in mid January 2022. We recommend users carefully review the changes as there is a high risk they could affect processing streams and the creation of downstream products. We draw your attention to the ‘Provision of negative radiometric values (implementing an offset)’. The new offsets are being applied to both L1C and L2A imagery, so any use of either product must take account of this. We do consume sentinel 2 imagery. Is there something which need to be handled from our end or the new processing is already being applied on the supplied products? Also, are there any other concerns which need to be addressed while consuming sentinel 2 imagery going onwards?

Same bounding box, different output AWS/EOCloud

Hi, I noticed that when I request a square bounding box with a WCS request in Python from AWS, it expectedly returns a square image (17*17 pixels): While when I use exactly the same WcsRequest to request exactly the same geometry from EOCloud (so only the source and a layer is different), the output is no longer a square image, but is a 13*15 pixels image. Do you know why this happens? Shouldn’t both be the same given exactly the same inputs? In both cases I feed the bounding box with coordinates in WGS84. Thanks!
