Retrieve point infrastructure features around an area

get_infra_point.Rd

Retrieve point infrastructure features around an area

Usage

get_infra_point(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 POINT containing point infrastructure features with standardized fields, including:

  • TYPE - Infrastructure type code derived from BDTOPO nature values:

    • PYL = Pylon / antenna

    • CLO = Steeple

    • CRX = Cross or calvary

    • EOL = Wind turbine

    • CST = Other point construction

    • GRO = Cave

    • GOU = Sinkhole

    • ORO = Other orographic detail

  • NAME - Toponym when available

  • SOURCE - Data source (IGNF_BDTOPO_V3)

Details

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

Retrieved layers include point constructions, orographic details, and pylons. Feature types are classified into standardized Sequoia codes based on their original nature attribute.

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