Hi, "The CC-BY-SA license permits you the free distribution of any data you download from my site, however if you make use of that right, this contract shall be terminated immediately and any advance fees paid by you will not be refunded."
you can put this statement in your terms & conditions but it is unlikely that in a court case this statement would be considered valid as your are working against the intention of the underlying license and the act of uploading the work (image) neither unlawful nor non-compliant with your terms. I think it would be easier to incorporate a very short cancellation period to the subscription service so that you can cancel the subscription anytime regardless of the reason. However, it is unlikely that you would be able to keep any advance payments for the subscriptions. You should rather use a set-up-fee, which cannot be claimed back in case of a cancellation of the service. Another option is to provide two image files: the map file with the share-alike-license and a transparent image file with the traffic data, which is licensed under a different license.
