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