I am having more fun with GIS, OSM and Wikidata and Russian administrative and municipal boundaries. So, since my last weekend:

  • I've downloaded a different dump of Russian OSM data (slightly better, but still wonky, on the plus side it already has my fixes)

  • Redownloaded Wikidata records for all referenced objects

  • Fixed a handful of OKATO mismatches (I should copy my fixes to Wikidata, though)

  • Decided to switch to OKTMO, since it looks like the census data is broken down by OKTMO

Did you know that "City district the city of Yaroslavl" and "the city of Yaroslavl" are two different entities? Coterminous, but distinct. Of course, Wikidata only has the latter, and OSM links its boundary to that Wikidata record. But since I'm checking that all second-level divisions of the OKTMO classifier are present in OSM data, this leaves me with... 795 records that aren't accounted for.

So, my plan for the upcoming week is:

  • ask if Wikidata plans to have cities like this as two distinct entities and either

    • prepare a batch upload of info into Wikidata and update OSM, or

    • go through all 795 records in my copy of the data and update them to point to the right OKTMO record

  • double-check that all second-level OKTMO entities are accounted for in OSM

  • match the OSM and Wikidata records with census results and update both

UPD: And here I am on Sunday night, composing a letter to the Ministry of Finance that their OKATO-OKTMO correspondence dictionary is missing whole cities...
