ggmap error??

The same (I think) code that used to work fine now gives me an error.

map1 <- get_map(location = c(lon = -99.340360, lat = 30.058052), zoom =

"auto", scale = "auto", maptype ="watercolor", source = "stamen")

Error in download.file(url, destfile = tmp, quiet = !messaging, mode =
"wb") :
cannot open URL
'http://maps.googleapis.com/maps/api/staticmap?center=30.058052,-99.34036&zoom=10&size=640x640&scale=2&maptype=terrain&sensor=false'
In addition: Warning message:
In download.file(url, destfile = tmp, quiet = !messaging, mode = "wb") :
cannot open: HTTP status was '403 Forbidden'

Question: I thought stamen was a different server from GoogleMaps. What
does this error cite googleapis??
Question: My understanding is that Google changed its access for geocoding
through its API and is now on a per-geocode basis. Is it possible that
get_map is also limited in a similar fashion.

Hi Dave â

Asking for a Stamen map will query Googleâs geocoding API if you give it a center/zoom specification.

Googleâs servers are rejecting your request (403 error), probably because youâre not using an API key.

I recommend installing the dev version at

if(!requireNamespace("devtools")) install.packages("devtools")
devtools::install_github("dkahle/ggmap", ref = "tidyup")

Then look at ?ggmap::register_google(). AFAIK, Googleâs static map service does not demand an API key, but I havenât revisited that issue in some time.

More generally, the code in ggmap can return different results over time because the infrastructure on which it is built itself changes.

Hope that helps!
david.

David,

I followed you suggestions(I think):

install.packages('digest')

if(!requireNamespace("devtools")) install.packages("devtools")
devtools::install_github("dkahle/ggmap", ref = "tidyup")

register_google(key = "myapikey")

us<-c(lon=-95.7129, lat=37.0902)
us_5<- get_map(location=us, zoom = 5, scale = 1)

and still get this error:

Source :
https://maps.googleapis.com/maps/api/staticmap?center=37.0902,-95.7129&zoom=5&size=640x640&scale=1&maptype=terrain&language=en-EN&key=xxx-PE8l_YV5466KpTeor6v8my6s
Error in get_googlemap(center = location, zoom = zoom, maptype = maptype,
:
Forbidden (HTTP 403).

If you have any other thoughts on other things to try, it would be great.

Thanks,

Rich
