N1: Infrastructure Distance Indicator — indicator_naturalness

Calculates distance to infrastructure (roads, buildings, urban zones) as a measure of remoteness from human influence. Follows tuto 04 methodology: distances from parcel centroids to roads (BD TOPO) and buildings, normalized to 0-100 and combined with weights (40

Usage

  units,
  roads = NULL,
  buildings = NULL,
  layers = NULL,
  column_name = "N1",
  lang = "en"
)

Arguments

units: sf object (POLYGON) of spatial units to assess
roads: sf object (LINESTRING/MULTILINESTRING). Road network (BD TOPO). NULL = default 1000m.
buildings: sf object (POLYGON/MULTIPOLYGON). Buildings. NULL = default 500m.
layers: nemeton_layers object. Used to resolve roads/buildings if not provided directly.
column_name: Character. Name for output column. Default "N1".
lang: Character. Message language. Default "en".

Value

sf object with added column N1 (score 0-100, 100 = very remote)
