Download cadastral parcels of Navarre in spatial format

catrnav_wfs_get_parcels_bbox.Rd

Get the spatial data of cadastral parcels by bounding box.

Usage

catrnav_wfs_get_parcels_bbox(x, srs, verbose = FALSE, count = NULL)

Source

SITNA – Catastro de Navarra

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.

srs

SRS/CRS to use on the query. See Details.

verbose

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

count

integer, indicating the maximum number of features to return. The default value NULL does not pass this parameter to the query, and the maximum number of features would be determined by the default value of the API service (5,000 in this case).

Value

A sf object.

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:25830 - ETRS89 / UTM zone 30N. 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:25830 (ETRS89 / UTM zone 30N) and the spatial object is projected back to the SRS of the initial object.
