In mongolmaps: Maps and Administrative Boundaries of Mongolia and Ulaanbaatar

mongolmaps 0.1.0

First CRAN release.
Boundaries at every open level, with a shared set of columns: mn_country(), mn_regions(), mn_aimags(), mn_soums() (including Ulaanbaatar districts), mn_ub(), mn_ub_districts() and mn_khoroos(), all built on mn_admin(). Simplified boundaries ship with the package; resolution = "high" downloads full-resolution ones once.
Bag level ready for NSO data: mn_bags() and mn_read_bags() read and check a bag boundary file, and codes and names of all bags are built in.
Names and codes: mn_match() resolves English spellings, Cyrillic, NSO codes, ISO 3166-2 codes and P-codes; mn_codes() lists every unit; mn_translit() romanises Mongolian Cyrillic (MNS 5217 or NSO style).
mn_join() joins data to boundaries in one step, detecting the level and dropping totals from NSO tables.
Mapping: mn_map() and theme_mn() for ggplot2, mn_leaflet() for interactive maps, mn_label_points(), mn_crs() and the mn_aimag_grid layout for geofacet.
Thematic layers: mn_settlements(), mn_neighbours(), mn_rivers() and mn_lakes() (major features bundled, all OpenStreetMap features with detail = "all"), and mn_roads(), mn_railways(), mn_airports() and mn_places() from OpenStreetMap, downloaded once and cached.
Rasters (with terra): mn_elevation() and mn_hillshade() (Copernicus DEM, 1 km national or 90 m by area), mn_landcover() (ESA WorldCover, 1 km or 10 m), mn_population() (WorldPop 2015-2030, 1 km or 100 m) and mn_zonal() to summarise them over any map units. mn_map() draws rasters as well as polygons.
mn_protected_areas() downloads the World Database on Protected Areas.
Data sources and cache: mn_sources(), mn_citation(), mn_download() (layer ids or groups such as "osm"), mn_cache_dir(), mn_cache_list() and mn_cache_clear().
Example data: mn_example_population.
