Hi,

To use BYOC it is important that the following criteria is met:

• Store your raster data in the cloud optimised geotiff (COG) format on your own S3 bucket in the supported region.
• Configure the bucket’s permissions so that Sentinel Hub can read them.
• Import tiles using the dashboard or API.

You can read the documentation about this in much more detail here.

In your case, I assume you are referring to this dataset: Digital Earth Africa ALOS PALSAR, ALOS-2 PALSAR-2 and JERS-1

Here, the dataset is not stored in a supported region, being stored in af-south-1 This means it is not compatible with BYOC.

A way around this would be to process and host the data yourself in an S3 bucket hosted and managed by yourself. However, it is important you make sure that it meets the terms of use set out by the dataset owners.

Let us know if you have any follow up questions, happy to help!
