catr_wfs_get_parcels_bbox: WFS INSPIRE: Download cadastral parcels

Description

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 on the bounding box provided. See Details.

• 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 = "parcel", srs, 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)

Value

A sf object.

Arguments

x

See Details. 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 could be "parcel" for cadastral parcels or "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 Details.

verbose

Logical, displays information. Useful for debugging, default is FALSE.

cod_zona

Cadastral zone code.

rc

The cadastral reference to be extracted.

API Limits

The API service is limited to the following constrains:

• "parcel: Bounding box of 1km2 and a maximum of 500. elements.

• "zoning": Bounding box of 25km2 and a maximum of 500 elements.

Details

When x is a numeric vector, make sure that the srs matches the coordinate values. Additionally, when the srs correspond to a geographic reference system (4326, 4258), the function queries the bounding box on EPSG:3857 - Web Mercator, to overcome a potential bug on the API side. The result is provided always in the SRS provided in srs.

When x is a sf object, the value srs is ignored. The query is performed using EPSG:3857 (Web Mercator) and the spatial object is projected back to the SRS of the initial object.
