I am doing an administrative map of the world using OSM data, and right now I’m mapping the data for The Netherlands, more specifically the Island of Aruba. I noticed that Oranjestad (city) has the same administrative level(8) as Oranjestad West and Orange Oost(East, I believe?).
My question is: does it make sense for all these elements to have the same admin level(8)? Because if the Orange West/East elements are different parts of the city Oranjestad then shouldn’t they have a lower admin level(for eample 9)? Because as of right now, there is no hierarchical criteria for these 3 elements, since they all have the same administrative relevance. Or should I take it that the info on OSM is correct as it is? If this is true, then one of these 3 will always be hidden, since they occupy the same space.
Thanks in advance for the help!
Using the same admin level for areas that are divisions of a larger area doesn’t make sense.
The administrative boundaries for overseas territories are not as well maintained as the ones in continental Netherlands because we have good reference data for the latter (BAG).
You should probably talk to Aleksandar Matejevic who added the Oost & West relations, he’s not part of the local community so YMMV.
Looking at the ways of relation 14034189 you can reverse engineer the broken relation that Aleksandar fixed in changeset 121381966, it has type=boundary name=Oranjestad Oost on way 1051307563, and those belong on the relation. The same goes for the other ways. Way 1058284863 has type=boundary boundary=administrative admin_level=8, and way 1062997228 only has type=boundary. The type=boundary tag does not belong on ways, only relations.
The wiki only defines admin_level=8 for “Districts (Municipalities) known as GAC regions”. The subdivisions of GAC regions should likely be considered similar to Wijken en Buurten in continental NL (they are not administrative boundaries, they use type=boundary boundary=placeplace=quarter/place=neighbourhood) that is a good suggestion for Orjanjestad Oost/West.
Oranjestad-West and Oranjestad-Oost are considered zones according to the Dutch Wikipedia, place=borough might be appropriate for these, because both are further subdivided in wijken & buurten (place=quarter & place=neighbourhood).
Thanks for the reply! I think I got what you said. I’ll talk to Aleksandar Matejevic, but it looks like Oranjestad-West/Oost aren’t administrative boundaries per se, just different zones of the city, which would make a change to them sound sensical. But I’ll ask Aleksandar for more infos.
It might be better to just remove the old boundaries for Oranjestad Oost/West and just keep the census ones. But I’ll leave that to the local community (if there is one, chances are good there a no active mappers on the island).
In changeset 123388237 I fixed the tags for the ways in the Oranjestad (city) relation and changed Oranjestad Oost/West relations to boundary=place tagging. That resolves the admin_level hierarchy issue.
