Retrieve road sections around an area

Usage

get_road(x, buffer = 1000)

Arguments

x

An sf object used as the input area.

buffer

numeric; Buffer around x (in meters) used to enlarge

Value

An sf object of type LINESTRING containing road sections with standardized fields, including:

  • TYPE - Road section type code, deduced from surface, numbering and importance attributes:

    • RN = National road (autoroutes, European roads, numbered roads starting with A, E, N, or departmental roads numbered > 900, as well as major slip roads)

  • IMPORTANCE - Road importance, taken from importance when available,

  • PRIVE - Road status, taken from prive when available,

  • RESTRICTION - Road restriction, taken from restriction_de_poids_total when available,

  • NOM - Road identifier, taken from cpx_numero when available, otherwise from cpx_toponyme_route_nommee

  • SOURCE - Data source (BDTOPO V3)

Details

The function retrieves road section layer from the IGN BDTOPO V3 dataset within a convex buffer around x.

If no road section data are found, the function returns an empty standardized sf object.
