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

[TomTom OSM]

Hello everyone!

Let us know if you have any more feedback.

If there are no more suggestions from your side, we will happily start the test run in the state of Louisiana as originally planned. After this, you’ll be able to take a look at all the changesets and see the outcome of our automated action. We will also keep you updated on the progress of our actions in this thread.

We are ready to start on Thursday 2/24/2022. Does this timing work for you?

Looking forward to hearing from you.
Marjan

It's a daunting task to update thousands of miles of coastline, bays, rivers, etc., after a weather event, esp. when the satellite imagery lags by months or years.

Probably a "best-effort" thing.

Having experience with editing some of the Lousiana coastal areas, it's several failed, incomplete, and possibly overlapping NHD imports with a mess of invalid multi-polygons, unclosed features, and any other error you can think of.

I would recommend against turning the bot loose on that geometry until simpler test cases are attempted.

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,

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.
