I am looking for a TopoJSON file that includes all countries including what I ended up after looking as 'sovereign countries' found in the following link:
Given the fact that the TopoJSON will be used in D3.js, it is stated that the TopoJSON files used in D3 are using vectors from 'Natural Earth' found here: http://www.naturalearthdata.com/downloads/110m-cultural-vectors/
However, the list of sovereign countries found in the 'Natural Earth' data is not the same - eg while Monaco is listed in wikipedia as a sovereign country it is not listed in the sovereign countries of natural earth. It is listed in the 'populated places' file though.
I am looking for a file that includes all countries including the sovereign countries - wikipedia version. I don't mind creating what is needed from scratch, so here I am asking for efficient ways to achieve what I want.
Googling around I found out that you can merge multiple GeoJSON files and then convert to TopoJSON, however the processes aren't very clear.
Looking for any pointers, tips, tools - getting a ready file would be an added bonus, but I would like to learn how to do it on myself.
In other words, is it easier to find a list, strip it and merge it?
Is there a way to manually add vectors and additional information on a TopoJSON directly?
Do I need to extract information from it, edit and re-build it somehow?
