Get the cadastral municipality code from coordinates

Retrieve the municipality code associated with an sf object or a coordinate pair.

Usage

catr_get_code_from_coords(
  x,
  srs = NULL,
  verbose = FALSE,
  cache_dir = NULL,
  ...
)

Arguments

x

Coordinate input. It can be:

• A pair of coordinates c(x, y). In this case the srs of the coordinates must be provided.

• A sf object. If the object has several geometries, only the first geometry is used. This function extracts coordinates using sf::st_centroid(x, of_largest_polygon = TRUE).

srs

SRS/CRS to use in the query. To see allowed values, use catr_srs_values, specifically the ovc_service column.

verbose

Logical. If TRUE, displays informational messages.

cache_dir

Path to a cache directory. If NULL or FALSE, the function stores cached files in a temporary directory. See base::tempdir().

...

Arguments passed on to mapSpain::esp_get_munic_siane

year

Character string or number. Release year. It must use format YYYY (assuming end of year) or YYYY-MM-DD. Historical information starts as of 2005.

resolution

Character string or number. Resolution of the geospatial data. One of:

• "10": 1:10 million.

• "6.5": 1:6.5 million.

• "3": 1:3 million.

region

Optional. A vector of region names, NUTS or ISO codes (see esp_dict_region_code()).

munic

Character string. A name or regex expression with the names of the required municipalities. Use NULL to return all municipalities.

Value

A tibble as described in Details. Returns NULL if the request fails.

Details

On a successful query, this function returns a tibble with one row including the following columns:

• munic: Municipality name used by the Spanish Cadastre.

• catr_to: Cadastral territorial office code.

• catr_munic: Municipality code as recorded by the Cadastre.

• catrcode: Full cadastral code for the municipality.

• cpro: Province code according to the INE.

• cmun: Municipality code according to the INE.

• inecode: Full INE code for the municipality.

• Remaining fields: See the API documentation.
