mongolmaps gives you ready-made maps of Mongolia. Everything in this vignette works offline: simplified boundaries ship with the package.

Administrative levels

Mongolia has 21 aimags (provinces) and the capital, Ulaanbaatar. Aimags are divided into soums, and soums into bags. Ulaanbaatar is divided into 9 districts (duureg) and those into khoroos.

Level in mongolmaps	Rural units	Ulaanbaatar units
`"country"`	Mongolia
`"region"`	4 economic regions	Ulaanbaatar is the 5th
`"aimag"`	21 aimags	Ulaanbaatar
`"soum"`	330 soums	9 districts
`"bag"`	~1,650 bags	204 khoroos

Each level has a function:

All of them return the same columns:

pcode: a code that identifies the unit at any level;
name, name_en, name_mn, name_mns: the name in the chosen language, in English (as NSO writes it), in Cyrillic, and in Latin with diacritics;
level, type, number: what kind of unit it is;
iso_code, nso_code: ISO 3166-2 and NSO statistical codes;
parent_pcode, region_pcode, aimag_pcode, soum_pcode: the units it sits in;
area_km2 and the geometry.

Filtering

Pass the places you want. Names can be spelled any common way.

Drawing maps

mn_map() draws any of these with ggplot2.

mn_map(mn_soums(aimag = c("Khovd", "Uvs", "Bayan-Ulgii")), fill = aimag_pcode, label = TRUE)

It returns a normal ggplot, so you can keep adding to it:

library(ggplot2)
mn_map(mn_aimags()) +
  geom_sf(data = mn_settlements(type = c("capital", "aimag_centre")), colour = "firebrick") +
  labs(title = "Aimag centres")

With context = TRUE you get neighbouring countries, rivers and lakes:

mn_map(mn_regions(), fill = name, context = TRUE)

Projections

Boundaries come in longitude and latitude (EPSG:4326). mn_map() projects them for you; to project them yourself use crs:

mn_aimags(crs = "albers")
#> Simple feature collection with 22 features and 15 fields
#> Geometry type: MULTIPOLYGON
#> Dimension:     XY
#> Bounding box:  xmin: -1182877 ymin: -601751.4 xmax: 1207275 ymax: 584211.5
#> Projected CRS: +proj=aea +lat_0=47 +lon_0=104 +lat_1=43.5 +lat_2=50.5 +x_0=0 +y_0=0 +datum=WGS84 +units=m +no_defs

mn_crs() returns the projections: Albers equal-area for national maps, UTM zone 48N for Ulaanbaatar.

Languages

mn_map(mn_aimags(lang = "mn"), label = TRUE, lang = "mn")

Set options(mongolmaps.lang = "mn") to use Mongolian everywhere.

Higher resolution

The bundled boundaries are simplified. For detailed work, use resolution = "high": the full-resolution boundaries (about 10 MB) are downloaded once and cached.

mn_soums(aimag = "Khovd", resolution = "high")
