Recently, in R, every time I try to query the OpenStreetMap database through the osmdata package, I get the following error:
Error in `httr2::req_perform()`:
! HTTP 405 Method Not Allowed.
I've always used this package to download data from OpenStreetMap directly in R, but now it's not working anymore. That's an example of the code I am trying to use, which should return the bounding box of a city:
library(osmdata)
city_bbox <- getbb(place_name = "Milan, Italy")
Its curious, if I get this code specifying the boundaries of bbox as vector it works.
library(osmdata)
library(mapview)
library(sf)
Castalla <- opq (bbox = c (-0.88,38.49,-0.47,38.74)) %>% #
add_osm_feature (key = "name", value = "Castalla", value_exact = FALSE) %>%
osmdata_sf ()
However trying this sample from the documentation still fails with the 405 error
q <- opq ("portsmouth usa") %>%
add_osm_feature (key = "amenity", value = "!restaurant") %>%
add_osm_feature (key = "amenity", value = "!pub") # There are a lot of these
Its very bizarre
Here's a workaround using packages nominatimlite and sf:
nominatim_polygon <- nominatimlite::geo_lite_sf(address = "Milan, Italy", points_only = FALSE)
bbox <- sf::st_bbox(nominatim_polygon)
It seems to be an issue within osmdata's get_nominatim_query function (getbb.R), which can be avoided by passing a vector to getbb() instead of a string. This vector can be obtained by passing through st_bbox() an sf polygon, which we can still get with nominalite::geo_lite_sf() while osmdata is giving this 405 error.
osmdata
packageVersion('osmdata'), mine osmdata-0.1.10, working as expected on above query.debugonce(osmdata::getbb)and stepped thru to wherehttr2::req_perform()appears?
