Retrieve OpenStreetMap data for a given location

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

Usage

get_osmdata(bb, city_name, river_name, crs = NULL)

Arguments

bb: Bounding box defining the area of interest
city_name: A character string with the name of the city.
river_name: A character string with the name of the river.
crs: An integer with the EPSG code for the projection. If no CRS is specified, the default is the UTM zone for the city.

Value

An list with the retrieved OpenStreetMap data sets for the given location

Examples

bb <- get_osm_bb("Bucharest")
crs <- get_utm_zone(bb)
get_osmdata(bb, "Bucharest", "Dambovita", crs)
