Currently I use a self-made template to link map positions in wiki-articles.
The following options are available:
{{MER-coordinates ... name of template
| name = ... displayed name
| logo = ... displayed logo (link to file) or "no", if no logo
| zoom = | latitude = | longitude = ... coordinates and zoom
| node = ... or node number
}}

Is it also useful for your articles?
