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.
