Bilingual maps, with toponyms and marginal information in both the majority and the minority language may be produced for the following reasons:

Cultural criteria

• Preservation of the cultural heritage of a people
• Inhabitants of minority language areas also pay taxes, so they also have the right to see their own geographical names on the topographic maps.

Current trends

• Increased bilingual representation or monolingual minority or regional names presentation.
• Marginal information translation more available

Procedure

• Delimitation of minority or regional language areas
• Introduction of bilingual transitional periods on the map
• Restoration of minority language names
• Exclusive minority language rendering
• Accompanied with bilingual marginal information rendering

For the demarcation of minority language areas,

language maps are needed.
