In mongolmaps: Maps and Administrative Boundaries of Mongolia and Ulaanbaatar

Soums of Mongolia and districts of Ulaanbaatar

Description

Returns the 330 soums (rural districts) together with the 9 districts (duureg) of Ulaanbaatar, which sit at the same level (type is "soum" or "district").

Usage

mn_soums(aimag = NULL, resolution = c("low", "high"), lang = NULL, crs = NULL)

Arguments

aimag	Keep only soums in these aimags (names or codes).
resolution	"low" (default) uses simplified boundaries that ship with the package and suit most maps. "high" uses full-resolution boundaries, downloaded once (about 10 MB) and cached; see mn_cache_dir().
lang	Language of the name column: "en" (English, as in NSO tables), "mn" (Cyrillic) or "mns" (Latin with diacritics, MNS 5217). Defaults to getOption("mongolmaps.lang", "en").
crs	Coordinate reference system of the result. NULL (default) keeps longitude/latitude (EPSG:4326). Use "albers", "lcc" or "utm" for a projection suited to Mongolia (see mn_crs()), or any value accepted by sf::st_crs().

Value

An sf tibble; see mn_admin() for the columns.
