Hi Geoff, Surprisingly, I'm a viking's maintainer but even many years later I still don't know how Viking works. :-)
So, the better is to post your query on the mailing-list. I forward your mail. I'm sure that some contributors can help you, much more better than me. An other way to have support around Map is to give details about the map source. Perhaps is there an easier solution.
