Get coordinates for a simple feature or bounding box object

An extended version of sf::st_coordinates() that supports binding coordinates to the object, optionally dropping the geometry, and returning wkt or a point on surface (geometry = "surface point") instead of the centroid.

Usage

get_coords(
  x,
  coords = NULL,
  geometry = "centroid",
  crs = NULL,
  keep_all = TRUE,
  drop = TRUE,
  call = caller_env()
)

get_minmax(x, crs = NULL, keep_all = TRUE, drop = TRUE)

Arguments

x: A sf, bbox, or sfc object.
coords: Column names to use for coordinates in results, Default: NULL; which is set to c("lon", "lat") by check_coords().
geometry: geometry to use for coordinates "centroid", "surface point", or alternatively "wkt"; defaults to NULL ("centroid").
crs: Coordinate reference system to use for coordinates; defaults to NULL.
keep_all: If TRUE, bind the coordinates columns to the provided object x; defaults to TRUE.
drop: If TRUE and x is an sf object, drop the geometry Default: TRUE.
call: The execution environment of a currently running function, e.g. caller_env(). The function will be mentioned in error messages as the source of the error. See the call argument of abort() for more information.

Details

get_minmax() get a bounding box for each feature (or group of features) appends the xmin, ymin, xmax, and ymax values for each feature to the simple feature object.
