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.

Examples

## Not run: 
# Get water body surrounding a particular point:
lat <- 54.33601
lon <- -3.07677
key <- "natural"
value <- "water"
x <- opq_enclosing (lon, lat, key, value) %>%
    opq_string () %>%
    osmdata_sf ()

## End(Not run)
