S1GRD sentinel-hub processing api - terrain correction not always being executed

HI, I am trying to download temporal tiles from sentinel-hub api and sometimes i noticed a pixel misalignment even if same orbit and same parameters just with different dates. It doesen’t always happen, but I noticed that sometimes the processing api doesen’t do the terrain correction. Not sure what does this depends on. But when I tried to download the non alignned image with same settings in requests builder the image was correctly aligned with the others. I’m currently using as backscatter coefficient: gamma0 (terrain) and as orthorectification: yes MAPZEN DEM and I’m working with IW products in VV,VH channels. Not other settings are specified a part the width, height which is always the same for all the temporal products in that area.

Statical API and PU calculation

Hi there, I need guide about 2 points and I really appreciate your help. First, when we use Statical API, what amount of PU and requests is calculated for (512*512 output) for the P10D interval and for one year as well ? And another question is that If we use P20D instead of P10D will there be any difference in the number of processing units and requests and the final calculation of them?

Landsat 8 imagery

HiI have been trying to download Landsat 8 images from USGS archive. When I search the thumb nails are displayed in the search results. When I select and try to visualize the image I am interested in the loading bar at the top of the screen begins as normal and speeds up to cross the rest of the display screen. (normally a sign that a script has failed.) No image is displayed.Can anyone advise why this is happening or am I doing something wrong when I try to display the image?Thanks,

NDVI values change but there was no change in ground cover

I have a site which I have been monitoring for several months and the NDVI values have been reasonable. Suddenly, the NDVI halved for no apparent reason. There was no change in vegetation or ground cover at the site so this drop in value was not caused by local ground conditions. The NDVI values, and dates, were: 2021-02-17: ndvi = 0.52 2021-02-22: ndvi = 0.23 I am using the FIS query to obtain the NDVI value (this is copied and pasted from the Sentinel documentation and is not my actual site. Due to confidentiality clause, I unfortunately cannot divulge the BBOX coordinates of my site): Requesting Stats Without a Histogram Query URL: http://services.sentinel-hub.com/ogc/fis/{INSTANCE_ID}?LAYER=5_VEGETATION_INDEX&STYLE=INDEX&CRS=EPSG%3A3857&TIME=2015-01-01%2F2015-10-01&BBOX=<BBOX_INFO>&RESOLUTION=10&MAXCC=5 Have others observed such rapid changes in NDVI when there is no apparent change in the vegetation or ground cover? Is there a known cause for such an

Merging EOPatches for Entire Sentinel-2 Scene

Hello everyone, I’m trying to download and process entire Sentinel-2 scenes. I break the scenes into 25 tiles (using BBoxSplitter) in order to stay below the 2500 x 2500 pixel service call limit. What I would like to do next is combine these patches into one for further processing. When I was testing my workflow, I was doing this manually (using numpy.concatenate for the relevant arrays part of my eopatches, like BANDS-S2_L1C.npy, etc.) for smaller areas and that worked fine. However, for entire scenes, I’m running into the issue that the scenes are so large that the number of horizontal pixels are not the same at the bottom and the top of a scene. That makes sense, but I’m having a hard time thinking about how I should combine entire scenes. The differences are small of course, but I’m not sure if dropping columns would create other problems. I saw ‘MergeEOPatchesTask’, but I’m a bit confused about the documentation and I can’t find any examples of its use. Is this what I’m looking f

Value of every band

Hello, I want to know the value of every color band. I know that: CoastalBlue=431 - 452nm B=465 - 515 G1=513 - 549 G2=547 - 585 Y=600 - 620 R=650 - 680 RedEdege=697 - 713 NIR=845 - 885 But when I try to know the value of them it is not the same. Example: evalscript = """ //VERSION=3 function setup() { return { input: [{ bands: ["Green"], units: "DN" }], output: { id: "default", bands: 1, sampleType: SampleType.FLOAT32 } }; } function evaluatePixel(sample) { var green = sample.Green return [green]; } The result it isn’t between G1=513 - 549, G2=547 - 585. I want to know please value of each band. Regards Antonio

How are pixels from different orbits combined in mosaic products?

I am back again with another orbit-related question about mosaic products! When I order a Sentinel 2 mosaic that covers multiple Sentinel 2 relative orbits, what is happening in the areas that are covered by multiple orbits? Are all pixels from all possible orbits evaluated in the evaluatePixel function? Or does evaluatePixel operate on data from each orbit separately then combine the independent results later? The information in the mosaicking documentation seems to be relevant but I do not fully understand the distinction between ORBIT and TILE as it relates to combining data from separate orbits. My goal is to account for orbit artifacts in the mosaic output images: Based on visual patterns in that image it looks like all pixels regardless of orbit are evaluated simultaneously in evaluatePixels. Is it possible to write an output layer that indicates which relative orbits contributed to the result for each pixel? Would it be possible to run evaluatePixels separately by relative orbit

Sentinel2 gets black images on some area

Dear all, I would need your help in solving a problem. Using your sample code for retrieving true-color images (or NDVI etc.) using Sentinel2 (L1C and/or L2A) , I can usually get a correct PNG image of an area that I query using the Polygon syntax, that I get from the relative geoJSON file. For some polygonal area requested, the images returned are always black, independently from the period asked – while in your Playground are visible (with the same constellation) and moreover are very near other areas whose images I get without problems. For instance, the following GeoJSON areas could be always retrieved with Sentinel (1 & 2): {“type”:“FeatureCollection”,“features”:[{“type”:“Feature”,“properties”:{“color”:“#3388ff”,“opacity”:1,“fillColor”:null,“fillOpacity”:0.2,“weight”:3,“dashArray”:null},“geometry”:{“type”:“Polygon”,“coordinates”:[[[10.550512,43.32638],[10.551357,43.325414],[10.55291,43.326183],[10.552379,43.327014],[10.550512,43.32638]]]}}]} {“type”:“FeatureCollection”,“featur

Landsat Image Distortion

Hi there,Is there any way to request the system to download raw 15x15m res. Band08 Landsat image?The code automatically returns 10x10m resolution (not native to the band) instead of 15x15. I have changed my x and y parameters in my WCS request to 10 by 10m but this only returns a distorted image (more distortion than in my original post) due to what I assume are 1 downsampling and 1 upsamling by the system.As the original resolution of the Band8 Landsat is 15 by 15m, is there any way to download it as such, without any need for up/downsampling?Many thanks,

SentinelHubRequest by image id

I couldn’t find in the documentation / examples how to request a specific image id. I would have a guess that it is something that could be provided to “other_args” when making a request, but I can’t see what would be valid here. I am using the Python API for information. To expand on what I am trying to do: I have implemented a search of the catalogue using SentinelHubCatalog to return a list of images meeting my criteria, I would then like to make my own selection from the list of images before going ahead and requesting the specific image for my AOI. I.e. provide SentinelHubRequest with simply an image id (e.g. ‘S1A_IW_GRDH_1SDV_20220728T175006_20220728T175031_044304_05499D_AFAE’) and a bounding box. Any guidance on meeting this aim would be very much appreciated!

Out of retries' HTTP 500 error'

Hi, I’m using Python and sentinelhub-py version 2.4.1 to fetch the full Sentinel2 image history of approx. 300 agricultural fields. I know this will put a large load on the web-service which may return HTTP 500 errors due to the load. I have tried to handle such errors by setting the following sentinelhub-py settings: from sentinelhub.config import SHConfig sh_config = SHConfig() sh_config.max_download_attempt = 5 sh_config.download_sleep_time = 60 sh_config.download_timeout_seconds = 30 However, using these settings I now get the following HTTP 500 error for multiple of my requests: Exception: DownloadFailedException('Failed to download with HTTPError:\n500 Server Error: Internal Server Error for url: https://services.sentinel-hub.com/ogc/wms/[INSTANCE_ID]?SERVICE=wms&BBOX=507395.0%2C6085280.0%2C507610.0%2C6085775.0&FORMAT=image%2Ftiff%3Bdepth%3D32f&CRS=EPSG%3A32632&WIDTH=43&HEIGHT=99&LAYERS=S2-L2A&REQUEST=GetMap&TIME=20

Multiple bands in a single request

Am currently using sentinal-hub python API and would like to know how to download multi-band images(>4) with a single request. The file formats supported: ‘png’, ‘json’, ‘jpeg’, 'tiff all allow 3-4 channels. How can this be done? The current request being made is: request_true_color = SentinelHubRequest( evalscript=evalscript_true_color, input_data=[ SentinelHubRequest.input_data( data_collection=DataCollection.SENTINEL2_L1C, time_interval=('2020-06-12', '2020-06-13'), ) ], responses=[ SentinelHubRequest.output_response('default', MimeType.PNG) ], bbox=betsiboka_bbox, size=betsiboka_size, config=config ) Thank you!

Sentinel-1 RTC (analysis-ready scenes) in S3 Bucket

Can you guys add your Sentinel-1 RTC analysis-ready data to open access registry as you have with you Sentinel-2 L2A data please? I found it in sentinelhub playground so clearly it is there. Just need a fast way to access the geotiffs. Or even if you put it in an S3 bucket that is somehow under a paid subscription that would be great (avoid any kind of API access).

Sentinel-1 ingestion delay

Hi, I’m using the WebFeatureService endpoint on the sentinel-hub python API to query for Sentinel-1 images. It seems that there is a delay in the ingestion of these images, no Sentinel-1 images are found for the month of May worldwide. A query on scihub shows that some data has been acquired during this time though. This is confirmed by aws s3 ls --request-payer requester s3://sentinel-s1-l1c/GRD/2021/ which currently only returns Jan-Apr. Do you have any more information on this, and when we can expect this delay to be absorbed? Thanks for your great service! Guillaume

Trouble using client id / client secret in python

What does the band's value signify of Landsat-8 L1C, Sentinel-2 L1C and MODIS MCD43A4

I was doing some processing on the Landsat-8 L1C bands downloaded from sentinel-hub. All the pixel values were between 0-1. Where as when i downloaded the same Landsat-8 LIC (level 1) scene from USGS EarthExplorer. Values of all the bands were between 0-65535. So, I know scenes downloaded from USGC gives you the DN values in level-1 product. So, what does the pixel values denote when downloaded from sentinel-hub for different sensors i.e. Landsat-8 L1C, Sentinel-2 L1C and MODIS MCD43A4

Download of s2cloudless results

Dear Sinergise,if I use your cloudmask (s2cloudless), I get two arrays, the cloud mask and cloud probability mask for each timestep. Did you include a function such as get_data(save_data=True) to save those arrays similar to the WcsRequest function, because if I want to do that on my own I would need geotransformation and projection information to save the numpy arrays as geotiffs. Although, I could find a workaround, I wanted to ask you first, if I overlooked a functionality of your service.Greetings

No available images on CRS change

I have been following this example:https://eo-learn.readthedocs.io/en/latest/examples/io/SentinelHubIO.html It works fine but when I change the line roi_bbox = BBox(bbox=[5.60, 52.68, 5.75, 52.63], crs=CRS.WGS84) to roi_bbox = BBox(bbox=[1475000.0, 5100000.0, 1495000.0, 5120000.0], crs=CRS(‘2193’)) there are no available images found. My guess is that CRS(‘2193’) which is NZGD2000 / New Zealand Transverse Mercator 2000 is not compatible. Although on this page https://docs.sentinel-hub.com/api/latest/api/process/crs/ its listed in the ‘other’ section. Can I not use this CRS format? The error message I get is: ValueError: During execution of task SentinelHubInputTask: No available images for requested time range: (datetime.datetime(2018, 4, 1, 0, 0), datetime.datetime(2018, 5, 1, 23, 59, 59))

Interpolated time-series

Hi, We are trying to run your example evalscript to create interpolated time-series images. Could you help us understand what bands_array_size and bands_array_n variables are? They create an inner-loop that names the outputs as B01_0 through B01_3 - these are driven by the bands_array_n variable (which we think is calculated as 4 in the example). The output response in the SentinelHubRequest example is described as ‘B01’, and so doesn’t match the output described in the evalscript, and it fails with a “Output B01 requested but missing from function setup()" error. Thanks
