A package for plotting maps in R with ggplot2

Overview

CRAN status Travis build status AppVeyor build status

Attention!

Google has recently changed its API requirements, and ggmap users are now required to register with Google. From a user’s perspective, there are essentially three ramifications of this:

  1. Users must register with Google. You can do this at https://cloud.google.com/maps-platform/. While it will require a valid credit card (sorry!), there seems to be a fair bit of free use before you incur charges, and even then the charges are modest for light use.

  2. Users must enable the APIs they intend to use. What may appear to ggmap users as one overarching “Google Maps” product, Google in fact has several services that it provides as geo-related solutions. For example, the Maps Static API provides map images, while the Geocoding API provides geocoding and reverse geocoding services. Apart from the relevant Terms of Service, generally ggmap users don’t need to think about the different services. For example, you just need to remember that get_googlemap() gets maps, geocode() geocodes (with Google, DSK is done), etc., and ggmap handles the queries for you. However, you do need to enable the APIs before you use them. You’ll only need to do that once, and then they’ll be ready for you to use. Enabling the APIs just means clicking a few radio buttons on the Google Maps Platform web interface listed above, so it’s easy.

  3. Inside R, after loading the new version of ggmap, you’ll need provide ggmap with your API key, a hash value (think string of jibberish) that authenticates you to Google’s servers. This can be done on a temporary basis with register_google(key = "[your key]") or permanently using register_google(key = "[your key]", write = TRUE) (note: this will overwrite your ~/.Renviron file by replacing/adding the relevant line). If you use the former, know that you’ll need to re-do it every time you reset R.

Your API key is private and unique to you, so be careful not to share it online, for example in a GitHub issue or saving it in a shared R script file. If you share it inadvertantly, just get on Google’s website and regenerate your key - this will retire the old one. Keeping your key private is made a bit easier by ggmap scrubbing the key out of queries by default, so when URLs are shown in your console, they’ll look something like key=xxx. (Read the details section of the register_google() documentation for a bit more info on this point.)

The new version of ggmap is now on CRAN soon, but you can install the latest version, including an important bug fix in mapdist(), here with:

if(!requireNamespace("devtools")) install.packages("devtools")
devtools::install_github("dkahle/ggmap")

ggmap

ggmap is an R package that makes it easy to retrieve raster map tiles from popular online mapping services like Google Maps and Stamen Maps and plot them using the ggplot2 framework:

library("ggmap")
#  Loading required package: ggplot2
#  Registered S3 methods overwritten by 'ggplot2':
#    method         from 
#    [.quosures     rlang
#    c.quosures     rlang
#    print.quosures rlang
#  Google's Terms of Service: https://cloud.google.com/maps-platform/terms/.
#  Please cite ggmap if you use it! See citation("ggmap") for details.

us <- c(left = -125, bottom = 25.75, right = -67, top = 49)
get_stamenmap(us, zoom = 5, maptype = "toner-lite") %>% ggmap() 
#  Map tiles by Stamen Design, under CC BY 3.0. Data by OpenStreetMap, under ODbL.

Use qmplot() in the same way you’d use qplot(), but with a map automatically added in the background:

library("dplyr")
#  
#  Attaching package: 'dplyr'
#  The following objects are masked from 'package:stats':
#  
#      filter, lag
#  The following objects are masked from 'package:base':
#  
#      intersect, setdiff, setequal, union
library("forcats")

# define helper
`%notin%` <- function(lhs, rhs) !(lhs %in% rhs)

# reduce crime to violent crimes in downtown houston
violent_crimes <- crime %>% 
  filter(
    offense %notin% c("auto theft", "theft", "burglary"),
    -95.39681 <= lon & lon <= -95.34188,
     29.73631 <= lat & lat <=  29.78400
  ) %>% 
  mutate(
    offense = fct_drop(offense),
    offense = fct_relevel(offense, c("robbery", "aggravated assault", "rape", "murder"))
  )

# use qmplot to make a scatterplot on a map
qmplot(lon, lat, data = violent_crimes, maptype = "toner-lite", color = I("red"))
#  Using zoom = 14...
#  Map tiles by Stamen Design, under CC BY 3.0. Data by OpenStreetMap, under ODbL.

All the ggplot2 geom’s are available. For example, you can make a contour plot with geom = "density2d":

qmplot(lon, lat, data = violent_crimes, maptype = "toner-lite", geom = "density2d", color = I("red"))

In fact, since ggmap’s built on top of ggplot2, all your usual ggplot2 stuff (geoms, polishing, etc.) will work, and there are some unique graphing perks ggmap brings to the table, too.

robberies <- violent_crimes %>% filter(offense == "robbery")

qmplot(lon, lat, data = violent_crimes, geom = "blank", 
  zoom = 14, maptype = "toner-background", darken = .7, legend = "topleft"
) +
  stat_density_2d(aes(fill = ..level..), geom = "polygon", alpha = .3, color = NA) +
  scale_fill_gradient2("Robbery\nPropensity", low = "white", mid = "yellow", high = "red", midpoint = 650)
#  Map tiles by Stamen Design, under CC BY 3.0. Data by OpenStreetMap, under ODbL.

Faceting works, too:

qmplot(lon, lat, data = violent_crimes, maptype = "toner-background", color = offense) + 
  facet_wrap(~ offense)
#  Using zoom = 14...
#  Map tiles by Stamen Design, under CC BY 3.0. Data by OpenStreetMap, under ODbL.

Google Maps and Credentials

Google Maps can be used just as easily. However, since Google Maps use a center/zoom specification, their input is a bit different:

get_googlemap("waco texas", zoom = 12) %>% ggmap()
#  Source : https://maps.googleapis.com/maps/api/staticmap?center=waco%20texas&zoom=12&size=640x640&scale=2&maptype=terrain&key=xxx
#  Source : https://maps.googleapis.com/maps/api/geocode/json?address=waco+texas&key=xxx

Moreover, you can get various different styles of Google Maps with ggmap (just like Stamen Maps):

get_googlemap("waco texas", zoom = 12, maptype = "satellite") %>% ggmap()
get_googlemap("waco texas", zoom = 12, maptype = "hybrid") %>% ggmap()
get_googlemap("waco texas", zoom = 12, maptype = "roadmap") %>% ggmap()

Google’s geocoding and reverse geocoding API’s are available through geocode() and revgeocode(), respectively:

geocode("1301 S University Parks Dr, Waco, TX 76798")
#  Source : https://maps.googleapis.com/maps/api/geocode/json?address=1301+S+University+Parks+Dr,+Waco,+TX+76798&key=xxx
#  # A tibble: 1 x 2
#      lon   lat
#    <dbl> <dbl>
#  1 -97.1  31.6
revgeocode(c(lon = -97.1161, lat = 31.55098))
#  Source : https://maps.googleapis.com/maps/api/geocode/json?latlng=31.55098,-97.1161&key=xxx
#  Multiple addresses found, the first will be returned:
#    1301 S University Parks Dr, Waco, TX 76706, USA
#    55 Baylor Ave, Waco, TX 76706, USA
#    1437 FM434, Waco, TX 76706, USA
#    Bear Trail, Waco, TX 76706, USA
#    Robinson, TX 76706, USA
#    Waco, TX, USA
#    McLennan County, TX, USA
#    Texas, USA
#    United States
#  [1] "1301 S University Parks Dr, Waco, TX 76706, USA"

There is also a mutate_geocode() that works similarly to dplyr’s mutate() function:

tibble(address = c("white house", "", "waco texas")) %>% 
  mutate_geocode(address)
#  Source : https://maps.googleapis.com/maps/api/geocode/json?address=white+house&key=xxx
#  "white house" not uniquely geocoded, using "1600 pennsylvania ave nw, washington, dc 20500, usa"
#  Source : https://maps.googleapis.com/maps/api/geocode/json?address=waco+texas&key=xxx
#  # A tibble: 3 x 3
#    address       lon   lat
#    <chr>       <dbl> <dbl>
#  1 white house -77.0  38.9
#  2 ""           NA    NA  
#  3 waco texas  -97.1  31.5

Treks use Google’s routing API to give you routes (route() and trek() give slightly different results; the latter hugs roads):

trek_df <- trek("houson, texas", "waco, texas", structure = "route")
#  Source : https://maps.googleapis.com/maps/api/directions/json?origin=houson,+texas&destination=waco,+texas&key=xxx&mode=driving&alternatives=false&units=metric
qmap("college station, texas", zoom = 8) +
  geom_path(
    aes(x = lon, y = lat),  colour = "blue",
    size = 1.5, alpha = .5,
    data = trek_df, lineend = "round"
  )
#  Source : https://maps.googleapis.com/maps/api/staticmap?center=college%20station,%20texas&zoom=8&size=640x640&scale=2&maptype=terrain&language=en-EN&key=xxx
#  Source : https://maps.googleapis.com/maps/api/geocode/json?address=college+station,+texas&key=xxx

(They also provide information on how long it takes to get from point A to point B.)

Map distances, in both length and anticipated time, can be computed with mapdist()). Moreover the function is vectorized:

mapdist(c("houston, texas", "dallas"), "waco, texas")
#  Source : https://maps.googleapis.com/maps/api/distancematrix/json?origins=dallas&destinations=waco,+texas&key=xxx&mode=driving
#  Source : https://maps.googleapis.com/maps/api/distancematrix/json?origins=houston,+texas&destinations=waco,+texas&key=xxx&mode=driving

  • get_map ignores the source argument

    get_map ignores the source argument

    I am trying to grab a map like this:

    get_map(location = c(6.815375, 51.217942), zoom = 11, source = "osm")

    Following error occures:

    Error in download.file(url, destfile = destfile, quiet = !messaging, mode = "wb") : can't open URL 'http://maps.googleapis.com/maps/api/staticmap?center=51.217942,6.815375&zoom=11&size=%20640x640&maptype=terrain&sensor=false'

    And an additional warning:

    W In download.file(url, destfile = destfile, quiet = !messaging, mode = "wb") : cannot open: HTTP status was '403 Forbidden'

    Why does ggmap query google, although source is set to "osm" ? And why is the status 403 forbidden?

  • GGMap error with aperm.default

    GGMap error with aperm.default

    I am trying to use GGmap to create a plot of vehicle car crashes by state. The map will have dots which are sized based on the number of car crashes in the state.

    In particular I am trying to recreate the usa-plot shown in the visualizing clusters section of this blog post.

    However, whenever I try to create the map I get this error.

    Error in aperm.default(map, c(2, 1, 3)) : 
      invalid first argument, must be an array
    

    I have setup the Google API and see that it is recieving hits. I have also enabled it and have the key.

    In addition I have installed GGmap from the github account using this command:

        devtools::install_github("dkahle/ggmap", ref = "tidyup", force=TRUE)
    

    since the CRAN one isn't updated.

    I have restarted and quit R several times as well but the error persists.

    Even if I just simply run:

        get_map()
    

    it still results in the error:

    Error in aperm.default(map, c(2, 1, 3)) : 
          invalid first argument, must be an array
    

    Below is my code, it is similar to the code in the blog post:

        mydata$State <- as.character(mydata$State)
        mydata$MV.Number = as.numeric(mydata$MV.Number)
        mydata = mydata[mydata$State != "Alaska", ]
        mydata = mydata[mydata$State != "Hawaii", ]
        devtools::install_github("dkahle/ggmap", ref = "tidyup", force=TRUE)
        library(ggmap)
        ggmap::register_google(key = "...") #my key is here
        for (i in 1:nrow(mydata)) {
          latlon = geocode(mydata[i,1])
          mydata$lon[i] = as.numeric(latlon[1])
          mydata$lat[i] = as.numeric(latlon[2])
        }
        mv_num_collisions = data.frame(mydata$MV.Number, mydata$lon, mydata$lat)
     
        colnames(mv_num_collisions) = c('collisions','lon','lat')
        usa_center = as.numeric(geocode("United States"))
    
    
        USAMap = ggmap(get_googlemap(center=usa_center, scale=2, zoom=4), 
        extent="normal")
        USAMap + 
           geom_point(aes(x=lon, y=lat), data=mv_num_collisions, col="orange", 
        alpha=0.4, size=mv_num_collisions$collisions*circle_scale_amt) +  
           scale_size_continuous(range=range(mv_num_collisions$collisions))
    

    I expect the map to output like this

    But I cannot seem to get passed this error.

    If anyone can help that would be great.

    Please let me know if you need any more information.

    Thank you.

    but... when i run ...

    map<-get_map(location= c(lon =15.500414, lat = 42.128677), zoom=8, maptype = "satellite", source = "google", color = "bw")

    I recive the same error:

    object register_google not found

    I'm trying to run a simple geocode of some addresses and when it runs it keeps giving me the error the object register_google not found. I decided to install version 2.7, because of the api key implementation which could help me easily track how many geocodes I actually do in a given time period, but I keep getting that error. Any help would be appreciated.

    startTime = Sys.time() geocoded = data.frame(stringsAsFactors = FALSE)

    register_google(key = 'Keepinitprivate')

    #Loop through my address list for(i in 1:nrow(facdata)) { result = geocode(facdata$fac_adr[i], output = "latlona", source = "google") facdata$lon[i] = as.numeric(result[1]) facdata$lat[i] = as.numeric(result[2]) facdata$geoAddress[i] = as.character(result[3]) } endTime <- Sys.time()

    Hi, this just started today. I had been using ggmap with no problem. I tried the ?get_map example code and it threw the same error. Did google make a change or something? looks like the get_map is getting a jpeg instead of a png and is throwing an error. Thanks for a great package and any help on the error.

  • Do not use OpenStreetMap export endpoint

    Do not use OpenStreetMap export endpoint

    The OpenStreetMap tile usage policy states

    Calls to /cgi-bin/export may only be triggered by direct end-user action. (For example: "click here to export".) The export call is an expensive (CPU+RAM) function to run and will frequently reject when server is under high load.

    Stitching images together like BigMap 2 or StaticMap do is a better option to avoid heavy load, but any usage of tile.openstreetmap.org still needs to follow the usage policy. I couldn't find a User-agent in the source, but all the technical usage requirements need to be met.

  • How to hide place names on the map

    How to hide place names on the map

    I have successfully found the place I need on the map, but the map also shows the names of many places in other countries. How do I get a map that does not display the place names, so as to highlight the places I marked. Thank you very much. Below is my R code: myMap <- get_map(location=myLocation, source="stamen", maptype="terrain-background", crop=FALSE) mymarkers <- read.delim('D:/my.txt', header=T) ggmap(myMap) + geom_point(aes(x=Long, y=Lat, color=population), data=mymarkers, size=4) + xlab("Longitude") + ylab("Latitude") + scale_color_manual(values=c("#C88AFF", "#EB746B", '#FCCC00', "#1EB5B8")) + theme(axis.text.x = element_text(color="black", size = 15), axis.text.y = element_text(color = 'black', size = 15), axis.title.x = element_text(color = 'black', size = 18), axis.title.y = element_text(color = 'black', size = 18), legend.position="none")

  • Feature Request: Flagging - not uniquely geocoded

    Feature Request: Flagging - not uniquely geocoded

    As I'm working with large sets of spatial data, I find that several of my locations are returning as not uniquely geocoded. For cleaning purposes, it would be nice for those that return as such to be flagged and then additional possible addresses to also be returned. See stackoverflow for current manual solution.

    Feature Request: progress bar option for ggmap::geocode()

    Hello,

    I don't know if this is the appropriate forum to submit feature requests, but...

    Would it be possible to develop a "progress bar" option for ggmap::geocode() and the related ggmap::mutate_geocode(), perhaps something similar to the progress bar returned by tidygeocoder::geocode()? This would help with managing workflow when attempting to geocode batches of addresses. Thanks!

  • ggmap has bad test for `base_layer`

    ggmap has bad test for `base_layer`

    Reproducible Example

    Example:

    reprex::reprex({
        library(ggmap)
        library(ggplot2)
        ggmap(get_map(), base_layer = ggplot())
    }, si = TRUE)
    

    This example generates a warning if you run it:

    Warning message:
    In missing(base_layer) || base_layer == "auto" :
      'length(x) = 9 > 1' in coercion to 'logical(1)'
    

    The problem is with the test base_layer == "auto". Since base_layer is a ggplot object, it's a list of length 9, and so that test fails.

    A fix for this is to use

    missing(base_layer || identical(base_layer, "auto")
    

    or perhaps

    missing(base_layer) ||
      (is.character(base_layer) && length(base_layer) == 1) && base_layer == "auto")
    

    instead. (The second test is a bit more lenient: the argument could have names or other attributes and still pass.)

  • get_map returns HTTP 400 Bad Request

    get_map returns HTTP 400 Bad Request

    The example in the get_map() documentation produces an error in my environment and it seems I cannot get a map with this function at all. For some reason reprex does not return the same error I see when executing the expression without reprex, so I am pasting directly from my console:

    ggmap::get_map(c(-97.14667, 31.5493))
    Source : https://maps.googleapis.com/maps/api/staticmap?center=31.5493,-97.14667&zoom=10&size=640x640&scale=2&maptype=terrain&language=en-EN&key=xxx-I0PSI858s2k0wWLKygpbWC97Ot74U
    Error in aperm.default(map, c(2, 1, 3)) : 
      invalid first argument, must be an array
    In addition: Warning message:
    In get_googlemap(center = location, zoom = zoom, maptype = maptype,  :
      HTTP 400 Bad Request
    

    I get a similar error when I try get_googlemap() directly:

    ggmap::get_googlemap(c(-97.14667, 31.5493))
    Source : https://maps.googleapis.com/maps/api/staticmap?center=31.5493,-97.14667&zoom=10&size=640x640&scale=2&maptype=terrain&key=xxx-I0PSI858s2k0wWLKygpbWC97Ot74U
    Error in aperm.default(map, c(2, 1, 3)) :

    In addition: Warning message:
    In ggmap::get_googlemap(c(-97.14667, 31.5493)) : HTTP 400 Bad Request
    

    At this point I cannot get any maps with these functions. I am registered with Google and e.g. geocode() works properly. Any help with this would be highly appreciated. Many thanks.
