How to download high size images?

Hello, I want to download high size images such as 49572x21256. However, unfortunatelly senitnelhub can just provide 2500x2500 size images. Is there any way to solve this problem ? I developed two algorithm but they do not work properly. first algorithm: To collect images: import numpy as np from shapely.geometry import MultiLineString, MultiPolygon, Polygon, shape import cv2 from sentinelhub import ( CRS, BBox, BBoxSplitter, ) import sentinelhub from shapely import geometry patch_x = 30 patch_y = 30 coords_ = [ [ [ 37.8111972, 38.724315 ], [ 43.552852, 38.724315 ], [ 43.552852, 36.614646

Request with specific time

I am wondering if I could get the NDVI layer for the specific dates, as far as I tested it it works for some dates, and for others it returns blank images. Could it be the range, for example can I see the NDVI for the month on January, does that make sense? This is my payload

Very High Resolution Image Mosaic 2018

I found this mosaic image for the German state of Mecklenburg-Western Pomerania, also from Sentinel 2:https://www.laiv-mv.de/static/LAIV/Geoinformation/Dateien/Luftbilder/Satellitenbild-Mosaik_M-V.zip I need this for Europe, too. How can I download the Very High Resolution Image Mosaic 2018? I am logged in, but there is no Download tab. Can I use a GIS program to download the tiles and merge them into mosaic of desired resolution? Thanks!

JSON Error for Sentinel-2 and Retrieval Error for Sentinel-1

I’m checking up on some imagery around Sri-Lanka and getting the following error message for Sentinel-2: JSON.parse: unexpected end of data at line 1 column 1 of the JSON dataI also had terrible luck looking for Sentinel-1 scenes:There was an issue fetching data for S1_AWS_IW_VVError retrieving additional data!These are theme parts which contain unavailable data sources:Sentinel-1 AWS IW VV+VHThis all worked previously (really simple visualisation stuff), so I’m not really sure what’s going on. Next week, I am (was?) planning to use EO Browser to demo a few things to my students, so I’m eager to sort this out as soon as possible.Thanks in advance

Fetching planetscope metadata

I am fetching metadata for S2L2A imagery using the catalog api as shown below which works fine. How should I fetch metadata for planetscope data? Code below works for sentinel-2-l2a const searchParams = { bbox, datetime: `${timeRange.from}/${timeRange.to}`, collections: ['sentinel-2-l2a'], limit: 100, }; const fetchData = () => { fetch('https://services.sentinel-hub.com/api/v1/catalog/1.0.0/search', { method: 'POST', headers: { 'Content-Type': 'application/json', 'Authorization': `Bearer ${token}`, }, body: JSON.stringify(searchParams), }) .then(response => response.json()) .then(data => { console.log(data); setCatalogData(data); const cloudCovers = data.features.map(feature => feature.properties['eo:cloud_cover']); setcloudCover(cloudCovers[0]) toast('Data fetched successfully'); }) .catch(error => { console.error(error); }); };

Can't get correct CLM and CLP mean values through Statistical Info Service

Hi to all, I am trying to follow this guide: https://www.sentinel-hub.com/faq/best-way-do-cloud-filtering-specific-aoi/ in order to get statistics for Cloud Coverage for specific AOIs with no luck. I can’t find the CLM and CLP bands as a product in the configuration layer. Thus I am using the “s2cloudless pseudoprobabilities” product. Also, the statistical info service is giving me NaN values. Maybe because I am using the wrong product? Could anyone advise me on this? Thank you in advance.

Analyze neighboring pixels for weed detection

Hi, We are trying to detect weeds on crops with sentinel2 images. Weeds often spread through the field in a different shape than the crop does, and that is useful for their detection. We wonder if, using a script, there is a way to analyze the shape of the “weed stain”, using neighboring pixels with same characteristics. For example, this 8 pixels have more than 3 points in chlorophyll and are next to each other in a vertical shape. Or, This pixel has more than 3 points in chlorophyll as well as 4 neighboring pixels. Any idea may be useful. Thank you!

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

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.
