[Talk-us] [bot] Proposal to fix issue with duplicated inner polygons in the United States

[TomTom OSM]

Hi Minh,

Thank you for your kind words, and valuable feedback!

I passed your suggestions to my team. They will take a closer look at them, and I'll get back with more details in a while.

Kind regards,
Marjan

Hi Marjan, at a glance, it looks like many of the issues involve multipolygons imported from NHD, since Louisiana has a very complex coastline and system of bayous. [1][2] I think many of us would welcome help cleaning up old NHD imports, particularly regarding topology issues.

If you later move on to other states, you may need to pay additional attention to occurrences of this warning that don't only involve natural multipolygons. For example, it's possible that a natural feature might be coincident to an enclave of a boundary relation. I'm unsure if mappers would prefer the boundary relation to be conflated with the natural feature or kept separate from it.
