Usage

geofabrik_zones

Format

An sf object with 476 rows and 9 columns:

id

A unique identifier. It contains letters, numbers and potentially the characters "-" and "/".

name

The, usually English, long-form name of the area.

parent

The identifier of the next larger excerpts that contains this one, if present.

level

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.

iso3166-1_alpha2

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").

iso3166_2

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.

pbf

Link to the latest .osm.pbf file for this region.

pbf_file_size

Size of the .pbf file in bytes.

geometry

The sfg for that geographical region. These are not the country boundaries, but a buffer around countries. Check oe_get_boundary() to extract the geographical boundaries.
