Apicarto Cadastre

Source: R/get_apicarto_cadastre.R
get_apicarto_cadastre.Rd

Implementation of the cadastre module from the IGN's apicarto

Usage

get_apicarto_cadastre(x,
                      type = "commune",
                      section = NULL,
                      numero = NULL,
                      code_abs = NULL,
                      source = "pci",
                      progress = TRUE)

Arguments

x

sf, sfc, character or numeric :

  • Shape : must be an object of class sf or sfc.

  • Code insee : must be a character of length 5 (see com_2025)

  • Code departement : must be a character of length 2 or 3 (DOM-TOM) (see dep_2025)

type

character : type of data needed, default to "commune". One of "commune", "parcelle", "section", "localisant".

section

character : corresponding to section of a city.

numero

character : corresponding to numero of cadastral parcels.

code_abs

character : corresponding to the code of absorbed commune. This prefix is useful to differentiate between communes that have merged

source

character : "bdp" for BD Parcellaire or "pci" for Parcellaire express. Default to "pci". See detail for more info.

progress

Display a progress bar? Use TRUE to turn on a basic progress bar, use a string to give it a name. See httr2::req_perform_iterative().

Value

Object of class sf

Details

Vectorisation:

Arguments x, section, numero, and code_abs are vectorized if only one argument has length > 1 (Cartesian product)

x = 29158; section = c("A", "B")
→ (29158, "A"), (29158, "B")

x = 29158, section = "A", numero = 1:3
→ (29158, "A", 1); (29158, "A", 2); (29158, "A", 3)

In case all vectorised arguments have the same length Pairwise matching is used

x = c(29158, 29158); section = c("A", "B"); numero = 1:2
→ (29158, "A", 1), (29158, "B", 2)

Ambiguous vectorisation:

If more than one argument has length > 1 but lengths differ, it is unclear whether to combine them pairwise or via cartesian product. This is rejected with an error to avoid unintended queries.

x = 29158, section = c("A", "B"), numero = 1:2
Possible interpretations:
1. Pairwise: (29158, "A", 1), (29158, "B", 2)
2. Cartesian: (29158, "A", 1), (29158, "A", 2), (29158, "B", 1), (29158, "B", 2)

Source:

BD Parcellaire ("bdp") is no longer updated and its use is discouraged. PCI Express ("pci") is strongly recommended and will become mandatory. See IGN's product comparison table.
