Get Minka Place as sf Object — mnk_place

Retrieve a Minka place as a simple features (`sf`) object given its `place_id`. The function queries the Minka API and returns the place boundary geometry together with descriptive metadata. The source GeoJSON is always in EPSG:4326 (WGS 84). By default the output retains this CRS, but an alternative CRS may be requested.

Usage

mnk_place_sf(place_id, crs = 4326)

Arguments

place_id: a single integer identifier for a Minka place. Each place has a unique identifier.
crs: coordinate reference system for the output geometry, supplied as an EPSG code or any value accepted by sf::st_crs(). Defaults to 4326.

Value

An sf object with one row per place and the following columns. Returns NULL invisibly if the request fails or the response is empty:

place_id: Place identifier, integer.
name: Place name, character.
display_name: Full display name, character.
slug: URL slug, character.
uuid: Universally unique identifier, character.
place_type: Type of place, character or NA.
admin_level: Administrative level, integer or NA.
bbox_area: Bounding box area, numeric.
location: Centroid as "lat,lon" string, character.
geometry: Simple feature geometry (POINT, POLYGON or MULTIPOLYGON), CRS 4326 unless transformed.

Examples

if (FALSE) { # \dontrun{
# Retrieve place 253 in WGS 84
place <- mnk_place_sf(place_id = 253)

# Retrieve the same place reprojected to ETRS89 / UTM zone 31N
place_25831 <- mnk_place_sf(place_id = 253, crs = 25831)
} # }
