An sf object of geographical zones taken from geofabrik.deSource:
sf object containing the URLs, names and file-sizes of the OSM

An sf object with 475 rows and 9 columns:
A unique identifier. It contains letters, numbers and potentially the characters "-" and "/".
The, usually English, long-form name of the area.
The identifier of the next larger excerpts that contains this one, if present.
An integer code between 1 and 4. If level = 1, then the zone corresponds to one of the continents (Africa, Antarctica, Asia, Australia and Oceania, Central America, Europe, North America, and South America) or the Russian Federation. If level = 2, then the zone corresponds to the continent's subregions (i.e. the countries such as Italy, Great Britain, Spain, USA, Mexico, Belize, Morocco, Peru and so on). There are also some exceptions that correspond to the Special Sub Regions (according to the Geofabrik definition), which are: South Africa (includes Lesotho), Alps, Britain and Ireland, Germany + Austria + Switzerland, US Midwest, US Northeast, US Pacific, US South, US West, and all US states. Level = 3L corresponds to the subregions of each state (or each level 2 zone). For example, the West Yorkshire, which is a subregion of England, is a level 3 zone. Finally, level = 4 correspond to the subregions of the third level and it is mainly related to some small areas in Germany. This field is used only for matching operations in case of spatial input.
A character vector of two-letter ISO3166-1 codes. This will be set on the smallest extract that still fully (or mostly) contains the entity with that code; e.g. the code "DE" will be given for the Germany extract and not for Europe even though Europe contains Germany. If an extract covers several countries and no per-country extracts are available (e.g. Israel and Palestine), then several ISO codes will be given (such as "PS IL" for "Palestine and Israel").
A character vector of usually five-character ISO3166-2 codes. The same rules as above apply. Some entities have both an iso3166-1 and iso3166-2 code. For example, the iso3166_2 code of each US State is "US - " plus the code of the state.
