Sentinel 5P Wms request issues

I followed the notification - change the end_point (base-URL) from https://services.sentinel-hub.com/ogc/* to https://creodias.sentinel-hub.com/ogc/* and tried both Wmsrequest and Wcsrequest. However, both requests give me the response: “503 Server Error: Service Unavailable for URL:” I have posted the request I made: request = WmsRequest( data_folder=‘data’, data_source=DataSource.SENTINEL5P, layer=‘CH4’, bbox=vancouver_bbox, time= (one_week_ago,today), width=512, height=856, image_format=MimeType.TIFF_d32f, config=config, maxcc = 0.5 ) request = WcsRequest(data_folder=‘test_dir’, data_source=DataSource.SENTINEL5P, layer=‘Methane’, bbox=vancouver_bbox, time=(one_week_ago,today), image_format=MimeType.TIFF_d32f, config=config) Please help for these issues. Thanks.

Image by S2A or S2B?

Hi Sentinel-team, When I pick a certain area taken by, lets say sentinal-2, is there any chance to find out if S2A or S2B has taken the image? I know they are more or less identical, and that L1C/L2A is also not helping… Thanks!

Script conversion to version 3

I have a formula to be converted into version=3 but did not manage to control the var val function. This way it works but better to have it in VERSION=3 var val = [[B11 - B10] - [0.389*[B12 - B10]]]; return colorBlend(val, [-0.003,0], [[0,0,0],[1,1,1]]); VERSION=3 could be: //VERSION=3 function setup() { return { input: [“B10”,“B11”,“B12”], output: { bands: 1 } }; } function evaluatePixel(sample) { let MCI =[[B11 - B10] - [0.389*[B12 - B10]]]; var val = MCI return colorBlend(val, [-0.003,0], [[0,0,0],[1,1,1]]); } BUT Failed to evaluate script! evalscript.js:9: ReferenceError: B11 is not defined let MCI =[[B11 - B10] - [0.389*[B12 - B10]]]; ^ ReferenceError: B11 is not defined at evaluatePixel (evalscript.js:9:12) at executeForSingleScene (:1119:17) Thanks a lot for an advice.

Speed of FIS vs Statistical API requests

Dears,We’ve been happily using the FIS API for quite a while now to fetch S-2 B04, B08, SCL for single pixels and subsquently visualize the NDVI time-series.The core function for this is fairly simple, the bounding box is typically 10x10m:from sentinelhub import FisRequestdef download_l2a_ext(bbox, percent_cc, config, download_cache='D:/Temp', bands=['B04', 'B08', 'SCL']): time_interval = ('2017-01-01', '2021-12-30') eval_script = 'return[' + ','.join([s for s in bands]) + ']' fis_request = FisRequest( layer='BANDS-S2-L2A', geometry_list=[bbox], time=time_interval, maxcc=percent_cc/100, resolution='10m', data_folder=download_cache, config=config, custom_url_params={CustomUrlParam.EVALSCRIPT: eval_script}, ) fis_data = fis_request.get_data(save_data=True)...This is fairly fast and with a few further steps of local compute (i.e. mask clouds and shadows, compute NDVI, put it in a matplotlib plot) one typically gets the

Change colour outside of GEOMETRY parameter

Is it possible to change the colour of the JPEG received in WMS when it falls outside of the GEOMETRY polygon? Currently it is white - I’d like a light greyish. I know I could change to PNG and set to TRANSPARENT but don’t want the PNG overhead. Cheers.

Sentinel2 transformation from L1C to L2A by myself

Hello, I have transformed L1C images from Sentinelhub to L2A by myself with Sen2Cor, because it has a time lag to be uploaded L2A image. However, I found that the images fails to transform from at the end of last month, although I hadn’t done the transformation from last September. I doubt it is because of the change in November Does anyone know the solution?

Tile is a little bit off

Hello! I’m comparing a polygon between August 11th and August 16th. I have 3 images : 11th, 14th and 16th. The true color image versus the polygon position is not exactly the same on August 14th. You can see the image Here’s the geojson polygon: geojson{ "type": "FeatureCollection", "features": [ { "type": "Feature", "properties": {}, "geometry": { "type": "Polygon", "coordinates": [ [ [ -72.61257469654083, 45.73771694446185 ], [ -72.61188268661499, 45.73771694446185 ], [ -72.61188268661499, 45.738136277988225 ], [ -72.61257469654083, 45.738136277988225 ], [ -72.61257469654083, 45.73771694446185 ] ] ] } } ] } Any idea why this is happening and if t

Problem retrieving sentinel data

I’m working on a project to get NDVI-data from Sentinelhub. I have an API of it’s own for handling connection to SentinelHub and processing it. The problem is that it seems to be working like a charm on everything else than on my laravel api, which it should be used on. I’ve tried to make the posts on plain curl and Guzzlehttp and it keeps failing… untill it doesn’t fail anymore. Then it start’s working. The data is always similar which goes to the ndvi-API and for some reason it works sometimes and sometimes it does not. And when it starts working, it works for hours. I do no changes to the code and it starts working. It also works very well and always with other API’s. Even when it fails on Laravel API. Any one had similar issue of any kind? There’s a lot of stuff going on on the Laravel API, but it’s a simple curl post and should be no problem with it, since the data arrives to the NDVI-API on the right form. Always. Thank you in advance.

Sentinel 5P NO2 layer

Statistical API- costum calculations

Hello, I’m using the Statistical API and I’m interested in adding custom calculations. Specifically, I want to calculate the percentage of pixels within a polygon where the NDVI (Normalized Difference Vegetation Index) value is higher than 0.8, or falls within a specific range. Is there a way to achieve this using the Statistical API? Below is my script for reference. Thank you! //VERSION=3 function setup() { return { input: [ { bands: [ "B04", "B08", "dataMask" ] } ], output: [ { id: "ndvi", bands: 1 }, { id: "ndviMask", bands: 1 }, { id: "dataMask", bands: 1 } ] }; } function evaluatePixel(samples) { let NDVI = index(samples.B08, samples.B04); let NDVI_R = (NDVI > 0.40 && NDVI < 0.8) ? 1 : 0; return { ndvi: [NDVI], ndviMask: [ NDVI_R ], dataMask: [samples.dataMask] }; } The result appears

Missing Dashboard Configurations

I have been creating and using multiple configurations for different KMZ. However, many of them appear to be missing. For example, i created 15A, 15B, 15C and 15D, but currently only 15B appears in my Configuration Utility I was able to use al four of them, they worked correctly, but now if i wanted to use them again i would have to create them from zero I would like some help to fix this or figure out what’s going on, i’m missing nearly 50% of all the configurations i’ve created Here are two examples of missing configs 12A: ‘XXXXXXXX-XXXX-4451-aa29-af77bec013af’ 12B: ‘XXXXXXXX-XXXX-481e-9b00-41c89a95801b’

SentinelS1L1C SNS Topic - nothing published since July 9 2022

We’ve had an active subscription for Sentinel 1 products for quite some time using the topic : arn:aws:sns:eu-central-1:214830741341:SentinelS1L1C. However, we’ve not seen a product published by the topic for a few days. We are aware of the Sentinel-1 downtime on July 9th 2022 - but we do see new products in the catalog that resumed on the 10th and 11th of July. Any information would be greatly helpful.

FIS: get_data method vs. POST request - different results

Because of the character limit in the URL I used the POST request to retrieve statistical information. But I got very low NDVI values. So I used the get_data method and the POST request to compare the statistical information for the same polygon. The results are quite different. Can somebody explain me why? Thanks Here is the configuration for the get_data method: from sentinelhub import SHConfig, CRS, constants, FisRequest, Geometry from shapely.geometry import Polygon class configuration: def use_modis(): sh_config = SHConfig() sh_config.instance_id = <INSTANCE_ID> sh_config.ogc_base_url = 'https://services-uswest2.sentinel-hub.com/v1/' sh_config.save() configuration.use_modis() geometry1 = Geometry(Polygon([(9.888827680050385, 48.51217273580289), (9.89264918894377, 48.51226462256068), (9.893282254167623, 48.51638404099815), (9.889316705153087
