Hello Team,
We have agriculture android app, in which we provide agriculture related information to farmers and now we want to integrate NDVI images with our app. I am trying to fetch images through API but i am getting some strange images.
i have used following request,
curl -X POST
https://services.sentinel-hub.com/api/v1/process
-H ‘Authorization: Bearer my-token’
-H ‘Content-Type: multipart/form-data’
-F ‘request={
