Retrieve infrastructure polygon features around an area

get_infra_poly.Rd

Retrieve infrastructure polygon features around an area

Usage

get_infra_poly(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 POLYGON containing infrastructure features with standardized fields, including:

  • TYPE - Infrastructure type code:

    • AER = Aerodrome runway

    • BAT = Building

    • CIM = Cemetery

    • CST = Surface construction

    • HAB = Residential area

    • SPO = Sports ground

    • VIL = Urbanized area (importance 1-2)

  • NAME - Toponym when available

  • SOURCE - Data source (IGNF_BDTOPO_V3)

Details

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

Retrieved layers include buildings, cemeteries, surface constructions, aerodrome runways, sports grounds, and residential or urbanized areas.

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