WFS INSPIRE: Download cadastral parcels

Source: R/wfs-cp.R
catr_wfs_get_parcels.Rd

Get the spatial data of cadastral parcels and zones. The WFS Service allows to perform several types of queries:

  • By bounding box: Implemented on catr_wfs_get_parcels_bbox(). Extract objects included in the bounding box provided. See Bounding box.

  • By zoning: Implemented on catr_wfs_get_parcels_zoning(). Extract objects of a specific cadastral zone.

  • By cadastral parcel: Implemented on catr_wfs_get_parcels_parcel(). Extract cadastral parcels of a specific cadastral reference.

  • Neighbor cadastral parcels: Implemented on catr_wfs_get_parcels_neigh_parcel(). Extract neighbor cadastral parcels of a specific cadastral reference.

  • Cadastral parcels by zoning: Implemented on catr_wfs_get_parcels_parcel_zoning(). Extract cadastral parcels of a specific cadastral zone.

Usage

catr_wfs_get_parcels_bbox(
  x,
  what = c("parcel", "zoning"),
  srs = NULL,
  verbose = FALSE
)

catr_wfs_get_parcels_zoning(cod_zona, srs = NULL, verbose = FALSE)

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

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

catr_wfs_get_parcels_parcel_zoning(cod_zona, srs = NULL, verbose = FALSE)

Arguments

x

See Bounding box. It could be:

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

  • A sf/sfc object, as provided by the sf package.

what

Information to load. It can be:

  • "parcel" for cadastral parcels.

  • "zoning" for cadastral zoning.

srs

SRS/CRS to use on the query. To check the admitted values check catr_srs_values, specifically the wfs_service column. See Bounding box.

verbose

logical. If TRUE displays informational messages.

cod_zona

Cadastral zone code.

rc

The cadastral reference to be extracted.

Value

A sf object.

API Limits

The API service is limited to the following constraints:

  • "parcel: Bounding box of 1km2 and a maximum of 5,000 elements.

  • "zoning": Bounding box of 25km2 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 overcome a potential bug on the API side.

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

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