Hello Good afternoon


I am trying to get the raw images for coordinates

tried to download the raw image from sentinel eo browser, the output image is giving nan as the image pixel value


Could you help me to fix this issue?


Thanks in advance,

Hey @swathi.kanle1


could you maybe share the EO Browser link with us. This would help us to check for which date and which collection you are getting problems.


Best,

Daniel


Hello Daniel,


here is the link I used to download the data


https://apps.sentinel-hub.com/eo-browser/?zoom=8&lat=30.52678&lng=72.90253&themeId=DEFAULT-THEME


I have requested for sentinel-s2-l1c, date 2021-06-19 (actually i tried downloading other dates aswell, for all the dates the value in nan)


Hi @swathi.kanle1,


It is not quite clear to me where you might be going wrong when downloading the imagery through EO Browser. When I search for Sentinel-2 L1C data from 19.06.2021 in the provided area of interest, the data is visualised correctly. Please follow this link to check for yourself.


In the download options you then choose the Analytical tab, probably change the image format to TIFF and tick all boxes for the raw bands as shown below.



I have no problems to display the downloaded data in e.g QGIS and you can see the values displayed for the cursor position in the lower left corner of the screenshot below.



What are the actual download options you used in the download interface? Do you have any more details for us so we can try and replicate the error you are experiencing?


I hope that helps,

Max


Hi Max,


Thank you for the response


Followed the same procedure as per your suggestions


But still we are getting zero values (we checked with QGIS )


We tried with EPSG:4326 as EPSG 3857 was not available in the coordinate system option


Here is the geojson i used with EO browser


{“type”:“FeatureCollection”,“features”:f{“type”:“Feature”,“properties”:{},“geometry”:{“type”:“Polygon”,“coordinates”:typ73.07856056839228,30.28329911154398],[73.07787459343672,30.283310982076873],,73.07785883545876,30.28380925363847],]73.07723723351955,30.28379738316585],]73.07718861848116,30.283297374392692],,73.07683825492859,30.283202989127027],,73.07682450860739,30.282224677605384],,73.07782463729382,30.282199778161473],,73.07790275663137,30.281683547569447],,73.07856727391481,30.28168181038956],]73.07856056839228,30.28329911154398],]73.07787459343672,30.283310982076873],,73.07785883545876,30.28380925363847],]73.07723723351955,30.28379738316585],]73.07718861848116,30.283297374392692],,73.07683825492859,30.283202989127027],,73.07682450860739,30.282224677605384],,73.07782463729382,30.282199778161473],,73.07790275663137,30.281683547569447],,73.07856727391481,30.28168181038956],]73.07856056839228,30.28329911154398]]]}}]}


Could you please help us to get the correct image pixel values?

Hi again @swathi.kanle1,


We figured out that you were using a faulty polygon that caused the error. It traces its own outline back and thus does not contain any area to request data with.


The following geojson works perfectly:


{
"type": "Polygon",
"coordinates": [
[
[73.07856056839228,30.28329911154398],
[73.07787459343672,30.283310982076873],
[73.07785883545876,30.28380925363847],
[73.07723723351955,30.28379738316585],
[73.07718861848116,30.283297374392692],
[73.07683825492859,30.283202989127027],
[73.07682450860739,30.282224677605384],
[73.07782463729382,30.282199778161473],
[73.07790275663137,30.281683547569447],
[73.07856727391481,30.28168181038956],
[73.07856056839228,30.28329911154398]]]
}

Cheers,

Max


Thank you so much for the help
