WFS INSPIRE: download addresses

Retrieve spatial address data through several types of WFS queries:

• By bounding box: catr_wfs_get_address_bbox() retrieves objects included in the provided bounding box. See Bounding box.

• By street code: catr_wfs_get_address_codvia() retrieves objects for specific addresses.

• By cadastral reference: catr_wfs_get_address_rc() retrieves objects for specific cadastral references.

• By postal codes: catr_wfs_get_address_postalcode() retrieves objects for specific postal codes.

Usage

catr_wfs_get_address_bbox(x, srs = NULL, verbose = FALSE)

catr_wfs_get_address_codvia(codvia, del, mun, srs = NULL, verbose = FALSE)

catr_wfs_get_address_rc(rc, srs = NULL, verbose = FALSE)

catr_wfs_get_address_postalcode(postalcode, srs = NULL, verbose = FALSE)

Arguments

x

Input defining the query area. See Bounding box. It can be:

• A numeric vector of length 4 with the coordinates that define the bounding box: c(xmin, ymin, xmax, ymax).

• An sf or sfc object from sf.

srs

SRS/CRS to use in the query. To see allowed values, use catr_srs_values, specifically the wfs_service column. See Bounding box.

verbose

Logical. If TRUE, displays informational messages.

codvia

Cadastral street code.

del

Cadastral office code.

mun

Cadastral municipality code.

rc

Cadastral reference to retrieve.

postalcode

Postal code.

Value

An sf object. Returns NULL if the data cannot be retrieved.

API limits

The API service is limited to a bounding box of 4 km2 and a maximum of 5,000 elements.

Bounding box

When x is a numeric vector, make sure that the srs matches the coordinate values. Additionally, the function queries the bounding box on EPSG:25830, ETRS89 / UTM zone 30N, to work around a potential API issue.

When x is a sf object, the value srs is ignored. In this case, the bounding box of the sf object is used for the query (see sf::st_bbox()).

The result is always provided in the SRS of the sf object provided as input.
