Retrieve linear infrastructure features around an area

get_infra_line.Rd

Retrieve linear infrastructure features around an area

Usage

get_infra_line(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 linear infrastructure features with standardized fields, including:

  • TYPE - Infrastructure type code:

    • CST = Linear construction

    • LEL = Power line

    • ORO = Orographic line

    • VFE = Railway line

  • NAME - Toponym when available

  • NATURE - Additional attribute (e.g. voltage for power lines)

  • SOURCE - Data source (IGNF_BDTOPO_V3)

Details

The function retrieves linear infrastructure layers from the IGN BDTOPO V3 dataset within a convex buffer around x.

Retrieved layers include linear constructions, power lines, orographic lines, and railway segments.

If no linear infrastructure data are found, the function returns an empty standardized sf object.
