Issue with Cloud Masking output with Process API

Process API allows us to get the Cloud mask together with the output band values as CLM or CPB. The pixe-wise CLM gives a wrong output on 2022-09-14 to 2022-09-17 some regions (I checked for some regions in Asia). But the "maxCloudCoverage"filter seems to be working fine. example which gave that the cloud cover is 0

Sentinel 2 Image Registration

Has anyone had problems with Sentinel 2 data not overlying exactly when looking at different image dates? Some scenes appear to be moving by at least one pixel (e.g. in Bands 2, 3 and 4). I am using L1C data.

Using platnet account to download data

Is there any difference if I use my planet account to download planetscope images rather than using sentinel apps such as eobrowser or request builder. If i download an area with planet account, then download the same area with different time using eobrowser. Does it count twice the quota or just one? It seems that data quality downloaded from planet account is better?

OsmSplitter class issue

Hi Sinergise,Find below a screenshot of an unexpected OsmSplitter output: I used zoom_level=12 as a parameter, but I see there are gaps between the generated output, whereas an OSM grid should not have any gaps. I tried to look into the source code but I cannot seem to spot the problem, so I was thinking that it may be due to a decimal rounding problem when dividing the latitude and longitude recursively to get to the specified zoom level.Let me know what you can find out. In the meantime I am not blocked, I am using the OSM grid through the CustomGridSplitter to get a gapless grid.Regards,

Discrepancy between FIS Request and EO Browser

Hi Guys, How are you doing? We’re facing some discrepancy between FIS Request and EO Browser I notice that in EO Browser the Cloud Coverage is made in frontend after the data is processed. What is better instance (NDVI for sentinel) to use ? This is the payload I am using in FIS Endpoint { layer: ‘NDVI’, style: ‘index’, type: ‘EQUALFREQUENCY’, time: ‘2018-10-11/2019-11-12’, geometry: ‘POLYGON((-13.5943150520325 -51.9328880310059,-13.5866761207581 -51.9432306289673,-13.5858178138733 -51.9427585601807,-13.5851311683655 -51.9431018829346,-13.5835433006287 -51.9399261474609,-13.5825991630554 -51.939582824707,-13.582170009613 -51.9367933273315,-13.581440448761 -51.9347763061523,-13.5818696022034 -51.9300556182861,-13.5943150520325 -51.9328880310059))’, resolution: ‘10m’, maxcc: 10, crs: ‘EPSG:4326’ } Look that both in my request and EO is using 10% of Cloud Coverage, but the Mean NDVI Curve is different

SHRateLimitWarning - Statistical API

I wrote a Python script that uses SentinelHubStatisticalDownloadClient (using sentinelhub version 3.5.0), in the same way as described in this tutorial. When I run it I get SHRateLimitWarning: Download rate limit hit warnings.warn("Download rate limit hit", category=SHRateLimitWarning) and the script seems to never finish execution. So I changed the script in this way, thinking that I could slow down the script and avoid multiple parallel calls to the API: client = SentinelHubStatisticalDownloadClient(config=config, n_interval_retries=3, max_retry_threads=1)client.rate_limit = SentinelHubRateLimit(num_processes=client.config.number_of_download_processes, minimum_wait_time=0.5)index_stats = client.download(download_requests) But I still get the same behaviour. Any help greatly appreciated.

Common_bad_payload

I’m using get_s2_evalscript from s2cloudless to get images from s2-L1C Here is how I do it in Python evalscript = get_s2_evalscript( all_bands=True, reflectance=True ) And the output looks like the following; //VERSION=3 function setup() { return { input: [{ bands: ["B01", "B02", "B03", "B04", "B05", "B06", "B07", "B08", "B8A", "B09", "B10", "B11", "B12", "dataMask"], units: "reflectance" }], output: { id: "bands", bands: 14, sampleType: "FLOAT32" } }; } function evaluatePixel(sample) { return [sample.B01, sample.B02, sample.B03, sample.B04, sample.B05, sample.B06, sample.B07, sample.B08, sample.B8A, sample.B09, sample.B10, sample.B1972, sample.B12, sample.dataMask]; } But when I run the following wcs_img = sh_request.get_data(save_data=True) I get the following error 400 Client Error: Bad Request for url: https://services.sentinel-hub.com/api/v1/process Server response: "{"status

WGS 84 and pyproj (python eo-learn workflow)

Hello all, Using a shape file for my area of interest, I am having trouble moving forward with the following error: ValueError: sentinelhub-py supports only WGS 84 coordinate reference system with coordinate order lng-lat. However pyproj.CRS(4326) has coordinate order lat-lng. I used the fiona.to_string command and get: +init=epsg:4326 {‘datum’: ‘WGS84’, ‘ellps’: ‘WGS84’, ‘no_defs’: True, ‘proj’: ‘longlat’} . Does sentinelhub-py automatically see EPSG=4326 and assume lat-long? Anyone else have this problem?

400 Client Error for SentinelHubInputTask (Sentinel 1)

Hello. Using SentinelHubInputTask, I want to retrieve S-1 data for a time period in multiple bboxes. I am requesting IW, descending, VV+VH, sigma0 backscatter coefficient, output in Float32.

ValueError: sentinelhub-py supports only WGS 84 coordinate reference system with coordinate order lng-lat. However pyproj.CRS(4326) has coordinate order lat-lng I get this error when I use the bbox_splitter = UtmZoneSplitter([country_shape], country.crs, 5000) Most probably the problem is with country.crs. Can you help me resolve?

Statistical API 'EXECUTION ERROR' for larger polygons

Hi, I have just signed up for a trail account and I am noticing that the workflow on the python documentation is not working with larger more complex geometries (> ~20,000 sq km). (Sentinel Hub Statistical API — Sentinel Hub 3.3.0 documentation) It works beautifully with simple and smaller polygons but anything larger (size of a large county or region) it seems to crash out with the following error: Is there a limit or something that might cause this? I am converting all polygons I pass through to EPSG:3857 [{‘data’: [{‘interval’: {‘from’: ‘2019-09-02T00:00:00Z’, ‘to’: ‘2019-09-03T00:00:00Z’}, ‘error’: {‘type’: ‘EXECUTION_ERROR’}}, {‘interval’: {‘from’: ‘2019-09-04T00:00:00Z’, ‘to’: ‘2019-09-05T00:00:00Z’}, ‘error’: {‘type’: ‘EXECUTION_ERROR’}}, {‘interval’: {‘from’: ‘2019-09-07T00:00:00Z’, ‘to’: ‘2019-09-08T00:00:00Z’}, ‘error’: {‘type’: ‘EXECUTION_ERROR’}}, {‘interval’: {‘from’: ‘2019-09-09T00:00:00Z’, ‘to’: ‘2019-09-10T00:00:00Z’}, ‘error’: {‘type’: ‘EXECUTION_ERROR’}}, {‘interva

Issue Retrieving Sentinel-2A Data for Year 2018

I have been utilizing your service to download Sentinel-2A images for remote sensing analysis. However, I recently encountered an issue when attempting to retrieve data for the year 2018. Specifically, the images I receive are entirely black, even though the same request for the year 2022 returns appropriate, usable data. Notably, this is a new issue. About six months ago, I used the same script for downloading data for 2018 and it worked perfectly, returning the expected images. Here are the specifics of my request: -I am utilizing the Sentinel Hub Python package to access and download the data. -The geographic region of interest is specified in a KML file, which I use to create the geometry for the request. -I am using an evalscript that requests all bands from the Sentinel-2A data. -The time interval I am requesting is from April 15th to October 1st, 2018. -The exact same request, but for the year 2022, returns expected, non-black images. Given these details, I am puzzled as to why

OGC API multiple instances

Hello, I have a web application set up, and I am using the configuration utility to set up an instance. From what I understand, using the OGC API enables only one output, therefore I have to choose if I want to return the pixel value or the visualization (while using eval script). I thought a workaround could be setting up two instances and then using one for the pixel value and the other for the visualization. Has anyone tried this? Or have different suggestions?

Problem with dowloading high-res print 350-600dpi

Hello, I consider to use a paid service of your hub. When I try to save a high-res print of 350-600dpi the process fails. Result does not depend on the size of the selected area. I get the same error when loading as one square kilometer and when loading 2000 square kilometers. How can you explain this?
