Hello BaghdadiMapper;
Thank you for your comment, Please Check the source I used to add this link in my changeset "Maxar SecureWatch Imagery 2023-04-15", Also Our team and Maxar have an agreement that allows us to use Maxar’s most recent nonpublic imagery for updates in OpenStreetMap. We always prioritize the use of public imageries, but at some locations where new changes are not seen in public imagery options, we will use Maxar’s nonpublic imagery to ensure the map is up to date
