add_osm_features | R Documentation |
Alternative version of add_osm_feature for creating single queries with multiple features. Key-value matching may be controlled by using the filter symbols described in https://wiki.openstreetmap.org/wiki/Overpass_API/Overpass_QL#By_tag_.28has-kv.29.
add_osm_features(opq, features, bbox = NULL)
opq |
An |
features |
Character vector of key-value pairs with keys and values enclosed in escape-formatted quotations (see examples). |
bbox |
optional bounding box for the feature query; must be set if no opq query bbox has been set |
opq object
add_osm_feature
vs add_osm_features
Features defined within an add_osm_features call are combined with a logical OR.
Chained calls to either add_osm_feature or add_osm_features()
combines
features from these calls in a logical AND; this is analagous to chaining
dplyr::filter()
on a data frame.
add_osm_features()
with only one feature is logically equivalent to
add_osm_feature()
.

## Not run: q <- opq ("portsmouth usa") %>% add_osm_features (features = c ( "\"amenity\"=\"restaurant\"", "\"amenity\"=\"pub\"" )) # This extracts in a single query the same result as the following: q1 <- opq ("portsmouth usa") %>% add_osm_feature ( key = "amenity", value = "restaurant" ) q2 <- opq ("portsmouth usa") %>% add_osm_feature (key = "amenity", value = "pub") c (osmdata_sf (q1), osmdata_sf (q2)) # all restaurants OR pubs ## End(Not run)
