One of the things to discuss is the style of the map - colors, borders, labels, etc.
For those participating, does it make sense to follow these conventions (adopted by English and other wikis) to define the styles of our default/general location map style?
I'd say that's a good starting point. The recent US convention might be more precise as it provides an extension for roads and urban areas. The basic principle of three background shades (fefee9 for area of interest, f6e1b9 for related areas and e0e0e0 for un-related areas) is the main thing to retain - that is the key element of the wiki house-style.
Boundaries: do not show when they coincide with a coastline, and make them as accurate as possible. The French national map on the examples page really suffers on both counts as a result, and the Rhône-Alpes map suffers from generalization when zoomed in too far.
Labels: Please translate according to the language preferences of the user - or the default of the project being used to access the map. For instance, a user on en should see "Moscow", a user on fr "Moscou" and on ru "Москва". Including the local version could be optional?
A different approach will be needed for showing the area of interest (as a solid red background will get awful if zoomed in too far), and points of interest need discussion. For instance what style pushpin, and please allow different styles within a single map as is used here
