I want to create history maps (maps showing historical borders) with inkscape and to have an object for each country.
I want to draw borders between countries only once and have this part of a path duplicated and assigned to the bordering countries.
E.g. I want to draw the border between France and Spain only once and have it assigned to both countries.
I know that I can simply draw each border as a separate path, cut out a part or use the whole path, copy it and merge each copy with the rest of the respective country's outline.
Is there a better approach to the problem?
Is there a tool, e.g. an Inkscape addon, that can identify all path part combinations that surround and therefore define areas?
