opq_enclosing: opq_enclosing

In osmdata: Import 'OpenStreetMap' Data as Simple Features or Spatial Objects

opq_enclosing

Description

Find all features which enclose a given point, and optionally match specific 'key'-'value' pairs. This function is not intended to be combined with add_osm_feature, rather is only to be used in the sequence opq_enclosing -> opq_string -> osmdata_xml (or other extraction function). See examples for how to use.

Usage

opq_enclosing(
  lon = NULL,
  lat = NULL,
  key = NULL,
  value = NULL,
  enclosing = "relation",
  timeout = 25
)

Arguments

lon	Longitude of desired point
lat	Latitude of desired point
key	(Optional) OSM key of enclosing data
value	(Optional) OSM value matching 'key' of enclosing data
enclosing	Either 'relation' or 'way' for whether to return enclosing objects of those respective types (where generally 'relation' will correspond to multipolygon objects, and 'way' to polygon objects).
timeout	It may be necessary to increase this value for large queries, because the server may time out before all data are delivered.
