I'll need to suggest checking local government websites, historical societies, or academic institutions in Viborg. Maybe recommend using keywords like "Viborg Mappen bilder," "patched maps Viborg," or similar in search engines or online archives. Also, suggest reaching out to relevant organizations for assistance in case the maps are not publicly available.
Finally, ensure the response is helpful but clear that if the maps are copyrighted, the user must comply with those laws. Encourage using official sources for legitimacy.
I need to be cautious about possible confusion with similar names. Viborg exists in both Denmark and Russia. The user might be referring to the Danish town, but if they're looking for a Russian Viborg, the maps would be different. I should mention both possibilities but focus on the Danish one unless there's more context.
