Note that in the above map, some countries aren't showing up, and there are lots of mistakes. That's because it's based on the actual current data in OGF put there by mappers. Countries with broken border relations don't show up at all. Other countries have out of date or incorrect information of various kinds in their labels.

In order for this to be successful, we would need to "clean up" our map data a lot
Just a test.....
 
The '''advantage''' would be that we could eliminate the need to maintain a separate overview map. We could create a script to re-generate this map on a regular basis.
 
In my offline OSM file, I added a tag called "ogf:status" that could be used to drive the coloring on the map. So the colors are based on my additions to the .OSM file.
 
One challenge was to get country labels that appear in a useful way. I did some data transformations using osmconvert and osmfilter first. To make typing the commands easier (I still haven't made a script), I named my files "o.osm", "ov.osm" etc. The effect of these transformations is to
 
* simplify the data set, eliminating as much irrelevant data as possible from the world file - no streets, no features... only coastlines and country boundaries
<pre>
>osmconvert o.pbf -o=o.o5m
 
>osmfilter o.o5m --keep="natural=coastline or admin_level<3 " -o=ov.osm
</pre>
* create a label node for the center of each admin_level=2 boundary relation and merge it into the osm file
<pre>
>osmconvert ov.osm --all-to-nodes -o=on.osm
 
>osmfilter on.osm --keep="@id>2000000000000000 and type=boundary and admin_level<3" -o=ob.osm
 
>osmconvert ov.osm ob.osm -o=om.osm
</pre>
 
Then we can open the output file, ''om.osm'', using Maperitive, with the following ruleset:
