Well, I think I fully understand all the diversity, but when you want the
shape of UK or Liberia, I presume most people expect the land, not the
maritime boundaries claimed ones or whatever.
This does not prevent to have 2 boundary relations, one for land boundary
and one including maritime ones
Thanks for all the advises and suggestion. I agree that in order to achieve
this, at least 2 tables/trees/dbs have to be maintained:
1 - The relationship of each admin_boundary on a certain level with its
parent (and the opposite) and whether this same boundaries applies for
other

2 - For each country, how to distinguish the land mass from territorial
waters. I am more interested on mapping the land mass, but the territorial
waters could be also generated if we have this distinction.
no, the landmass is the land

Hi Frederik, regarding software, I am already familiar with Mapit scripts
code, which are able to extract admin boundary polygons for each level (it
is not creating relationships though). How do you see Nominatim or
Osmium/osmjs better for the purpose? Reading osmjs documentation, I see it

you don't need them, and you will put unneccessary heavy load on the db
creating a relation with all coastlines and the land side borders

Frankly, I find the idea of using the coastline as an admin boundary
rather silly. This would mean that if you step out 1 foot into the
water, you've left the state or country.
indeed it seems to be different: en.wikipedia.org/wiki/Territorial_waters

The important issue here is that there is lots of potential uses here
(layers are not used exclusively for creating maps, they can also be used
for analysis) and there are people wishing to use these datasets: the
administrative boundaries based on coastline (call them whatever you want),
the ones
That sounds interesting. I am not familiar with Nominatim, but I have
correctly understood, the result is a Postgres/postgis database with all
those polygons and hierarchies. This could be an interesting approach as
the post-processing could be directly done there using PostGIS predicates.
Thanks Eugene, that looks really promising.
I've seen there is an API to query Wikidata (results can be list of
Wikidata item IDs encoded as JSON), but I don't see the way to get the item
itself as JSON (or any other parseable format). Is it on the way?

Hi,
I plan to create and make easily available a world-wide administrative
layer based on OSM data, ideally including existing administrative codes

We've built a database using GADM, GAUL, and Natural Earth. We initially

I recently had to deal with admin boundaries and the lack of homogeneous

For example US states had only the usual 2 letters
