Data values from visualize analytical and Copernicus scihubare are different

I compared Sentinel-2 Band-8 from Copernicus scihub and from visualize analytical. The pixel values are different from these two sources. Ex. 0.27 in visualize analytical but 0.36 in Copernicus scihub. Any explanation could be? I understand that visualize analytical did some Geo transformation, but I think the difference cannot that much.

Creating a custom (and free) CalTopo layer with Sentinel imagery?

I’d like to help create a custom (and free) CalTopo layer with Sentinel imagery. To start, I’d go to CalTopo dot com and select “Add/Custom Source”. I then need to add 1 or 2 URL’s for “URL Template” and/or “Auto-Configure URL”. As an example, here is a CalTopop map with a custom layer that has snow-depth estimates. Default Map The “URL Template” for the custom “Snow Depth” layer is:Export Map (NWS_Observations/NOHRSC_Snow_Analysis)},{right},{top}&bboxSR=102100&imageSR=102100&size={tilesize},{tilesize}&f=image Is there a URL such as this I can use to create a custom (and free) CalTopo “Sentinel Imagery” layer? Thanks!

Process API - how to handle 'exceeded limit'

Hi there!I’m experimenting with the Process API through the python library, so far they are very practical and intuitive to use.However, I do have a couple questions since I find the documentation a bit lacking on some aspects, in particular:Is the output file always called “response.tiff”, or can it be customized? with large areas, I noticed that the requests consume all the processing units per minute available. This is not an issue per se, however the get_data call does not raise any exception and still returns a completely blank image while printing a warning “rate limit exceeded”, which is not ideal. How should I handle this? Is there a way to check whether the response was successful or generated a “rate limit exceeded” error? Or even better, could the client be configured so that the requests per minute are limited/scheduled over a longer period to avoid such problem?Thank you very much, and sorry in advance if this info is available somewhere, I couldn’t find anything relevant.

Problems in my access to the WMS service endpoints in QGis

Last week my account had reached the limit of processing units. So we upgraded to the Basic plan and the purchase has already been approved. However, when entering the WMS URL in QGis, to add a new layer, I get the following error: Download of capabilities failed: Error transferring https://services.sentinel-hub.com/ogc/wms/{My ID}? SERVICE=WMS&REQUEST=GetCapabilities - server replied: Forbidden I’ve been using WMS for over two years and I’ve never received this error. It occurs both in different versions of QGis as well as in different internet networks. Can anybody help me?

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

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!
