get_osmdata: Retrieve OpenStreetMap data for a given location

Description

Retrieve OpenStreetMap data for a given location, including the city boundary, the river centreline and surface, the streets, the railways, and the buildings

Usage

get_osmdata(
  city_name,
  river_name,
  network_buffer = NULL,
  buildings_buffer = NULL,
  city_boundary = TRUE,
  crs = NULL,
  force_download = FALSE
)

Value

A list with the retrieved OpenStreetMap data sets for the given location, as objects of class sf::sfc

Arguments

city_name

The name of the city as character vector of length 1, case-sensitive. Required, no default.

river_name

The name of the river as character vector of length 1, case-sensitive. Required, no default.

network_buffer

Buffer distance in meters around the river to get the streets and railways, default is 0 means no network data will be downloaded

buildings_buffer

Buffer distance in meters around the river to get the buildings, default is 0 means no buildings data will be downloaded

city_boundary

A logical indicating if the city boundary should be retrieved. Default is TRUE.

crs

An integer or character vector of length one with the EPSG code for the projection. If no CRS is specified, the default is the UTM zone for the city.

force_download

Download data even if cached data is available

Examples

if (FALSE) { # interactive()
# Set parameters
city <- "Bucharest"
river <- "Dâmbovița"
crs <- "EPSG:31600"  # National projected CRS

# Get OSM data with defaults
get_osmdata(city_name = city, river_name = river)

# Get OSM data without city boundary
get_osmdata(city_name = city, river_name = river, city_boundary = FALSE)

# Use custom network buffer to get streets and railways
get_osmdata(city_name = city, river_name = river, network_buffer = 3500)

# Use custom buffer to get buildings
get_osmdata(city_name = city, river_name = river, buildings_buffer = 150)

# Use custom CRS
get_osmdata(city_name = city, river_name = river, crs = crs)

# Avoid getting OSM data from cache
get_osmdata(city_name = city, river_name = river, force_download = TRUE)
}
