Thanks for reaching out to us. For citing imagery sourced from Sentinel Hub you can refer to here. Images from the Sentinel Copernicus program are non-commercial so it is no problem to share them
As for accessing the satellite image that you require, we are aware of some issues with accessing and visualising the image currently and looking to fix this. I can only apologise for the inconvenience.
Hi Lisa, this should be working correctly now, so you should be able to obtain your image. If you need any assistance then please let us know, happy to help. In addition, there’s some additional citations for Sentinel imagery you will need to add, you can find the info for this here.
