Sentinel s2 l1c - 502 error by cloudfront - Unable to access meta-files and preview image from http

Hi, Until last week/month we were able to access public url like:https://roda.sentinel-hub.com/sentinel-s2-l1c/tiles/43/Q/EV/2018/12/16/0/ which used to display list of files and folders. I can still access the metadata.xml directly using url like:https://roda.sentinel-hub.com/sentinel-s2-l1c/tiles/43/Q/EV/2018/12/16/0/metadata.xml To check what dates the data is available and to check product information, we used to hit:https://roda.sentinel-hub.com/sentinel-s2-l1c/tiles/43/Q/EV/2018/12/ that used to give list of dates (in json format). But now we are getting 502 error as shown below:

Sentinel-2 L2A multiple reprocessed versions?

Dear all, I’m aware of the current reprocessing campaign and also that an increased sequence number can come from different datatakes as well as reprocessing a scene (e.g., mentioned in this recent thread). However, the following example shows a scene processed with baseline 02.14 (_0_L2A) and two versions reprocessed to baseline 05.00 (_1_L2A, _2_L2A) but with different valid_cloud_cover-flags. As far as I could see this is not an individual case but can be found frequently. I have not found any information about this and hope I’m in the right place to ask. The scenes are from Digital Earth Africa but point a Sentinel-Hub AWS bucket.

Missing metadata (.xml) on AWS

Hello, I am interested in two files typically found in Sentinel2 granules: MTD_MSIL1C.xml and MTD_TL.xml. Looking on the L1C AWS bucket I see that MTD_TL.xml has been renamed to metadata.xml. However, I cannot find the MTD_MSIL1C.xml file anywhere. Where is this file? Thank you

API DataFilter and Acquisition Date

Hi, I am using the Sentinel Hub API feature and having success in donloading single images, however, if i use the DataFilter function to set a “from” and “to” time frame it wont download all the images within this range. The WMS function works well here but can this be done in the API. Example code that i am using where a single file is downloaded. So basically i am not sure why a data range is needed. “data”:[{“dataFilter”:{“timeRange”:{“from”:“2019-10-01T00:00:00.00Z”,“to”:“2019-12-31T00:00:00.00Z”} Also, is there a way to save the file (again like the WMS functions) but with the actual acquisition date of the file. Using the API i get a string of code followed by -response.tiff.

How Sentinel Hub's get image by specific date works?

I know how to specify date, when creating request in Sentinel Hub. But some areas come back as just black or white polygons. Does it mean that SH does not have images for those dates? And if it does not, how do I request latest existing image. Also, when time range is more than one day, how is this image constructed? Feel free to send me back to official docs in case I missed something. P.S. I am using Sentinel-2-L2A, making requests via Requests Builder web interface and also Python package sentinelhub.

Get Sentinel-1 image with decibels values

Hello,I’m using sentinelhub-py and i’m trying to understand how to get the images as arrays with decibels values. I think I have asked it before but maybe mmy question was not clear enough so I will try to make it clearer.under “confiduration utility” I have created configuration with serveral layers, among them some sentinel1 layers, as:TRUE-COLOR-S1-IW - which uses the function return [VV,VH, 2 * VH, VV / VH / 100.0]VV -which uses the function:return [Math.max(0, Math.log(VH) * 0.21714724095 + 1), dataMask];VH- which uses the function:return [Math.max(0, Math.log(VH) * 0.21714724095 + 1), dataMask];Now, i’m trying to use evalscript in order to get image with 3 dimensions.bands : vv, vh and the datamask.As I undersand, according to my configuration layers (the return), I suppose to get back my values as db, e.g 0 to -20, but anytime I use the get data, and print the result array, I see that the result is in UINT8 (0-255 and not -20-0 ).This is how I tried to call teh VV,VH and datamas

Same images has two different IDs

I have the same image, i.e. same acquisition date, same geography, etc. but they have two different IDs.

Doubts about EOPatches for Slovenia 2019 datasets

Hi!My current job is land cover classification from sentinel-2 images, and I want to use EOPatches for Slovenia 2019 datasets. But I have some doubt about the LULC label. In the blog ,the sentinel-2 images are in 2017,but in the AWS S3 Cloud Object Storage the images are in 2019, do they use the same groud truth? For the ground truth, I only find 2017 Slovenia land use map in the official websit, so if the dataset use 2019 sentinel-2 images and 2017 land use map, will it cause problems? And I can’t find the useful link of the EOPatches for Slovenia 2017 datasets.Could you generously explain it? Appreciate your help.Thanks and regards.

Understand the uuse of processing unit and number of request

Hello,I have some issue understanding how Sentinel-Hub credit is used and calculated (processing unit and request).I have a leaflet WebMap that showed Sentinel image through Sentinel-Hub WMS. I put the Sentinel Hub WMS through Geoserver WMS manager. This is just to keep WMS address more management, so if I change something in the Sentinel Hub that create a new WMS address, I only need to replace it in Geoserver but don’t need to touch the code. I belive by puting Sentinel Hub through Geoserver, I did not create any complication to the request from Sentinel Hub service.I’m currently on Basic account that give me 70,000 procesisng unit and 700,000 request per month. I recently check that with only minor used, my account was using ~4000 processing unit it just a few hour. So if the Webmap is under moderate use by 10 peoples, the procesisng credit might be enough for just a few days.Trying to quantifying this I put down some rough estimation as follow:one screen size would be about 100 til

NDVI Value differences

I am calculating NDVI from S2-L2A images downloaded from Copernicus Open Data using sentinelsat in QGIS(raster calculator) & following this tutorial (I saved xarray to tif for comparison). I observe that the values obtained are different from both the methods, as original band values also differ by around 1000, hence the mean also varies & there is significant difference among the two means obtained for my interest area. I used a recent image of year Nov’2022. The mean value obtained from sentinelsat images is low as compared to NDVI from the pystac method. (for same area of interest) I am also confused about the values for individual bands I am getting, are these values DN or reflectance, as per the documentation and values I think both are reflectance multiplied by 1000. The image shows comparison for the values for NIR band (Band 8) for both sources, as we can see both max & min values are different for both sources and also the value at a point is different by 1000 (whi

Calculate available rate limits per request

Hello Forum! How could I calculate resulting rate limits per request??? Somehow rate limits exceeded, nonetheless the dashboard says: 500 processing units per 1 minute. 70 000 processing units per 31 days. This is very inconvenient issue, which frustrated severely my workflow! Thanks for suggestions!

Plot sentinel1 image creates weird dots image

I have created in my confiduration sentinel 1 layer by inserting the following script in the costum sccript editor: return [VV,VH, 2 * VH, VV / VH / 100.0] ( like in the documentation + VH channel). I used wms_Request and get data and then plot the image but I got image with dots : bbox_size,bbox,bbox_coords_wgs84=get_bbox_from_shape(shapes,10) s1_request = WmsRequest( data_collection=DataCollection.SENTINEL1_IW, layer='TRUE-COLOR-S1-IW', bbox=bbox, time=('2020-11-01', '2021-01-10'), width=bbox_size[0], config=config ) s1_data = s1_request.get_data() plot_image(s1_data[-3]) I’m not sure why is this hapenning ans would love to understand it better and get help with hoe to solve it.
