  D = 100,
  buffer_distance = 120,
  show_time = TRUE
)

Arguments

osm_data	List containing OSM data (highways, green_areas, trees).
crs_code	Coordinate reference system code for transformations.
D	Distance decay parameter (default = 100).
buffer_distance	Buffer distance for spatial joins (default = 120).
show_time	Logical, whether to print processing time (default TRUE).

Value

A spatial data frame with calculated green index.
