Nov 14, 2017 · A good example of this is ggmap. The ggmap package allows you to download and plot basic maps from Google maps (and a few other sources). These maps can then be used as layers within the ggplot2 plotting system. Essentially, you can plot maps from ggmap, and then use ggplot2 to plot points and other geoms on top of the map.

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.

The examples below documents ggmap syntax, starting with Google basemaps as examples. HOWEVER, the output for the last examples, stamen maps, work best. Google made significant changes to their Maps API in 2018. Because of this, ggmap for Google maps is less convenient than before, especially when generating quick static maps.

Center/zoom. While Stamen Maps and OpenStreetMap require the bounding box format for obtaining map tiles and allow you to increase or decrease the level of detail within a single bounding box, Google Maps requires specifying the center coordinate of the map (a single longitude/latitude location) and the level of zoom or detail.zoom is an integer value from 3 (continent) to 21 (building).

As a consequence, ggmap will not know if another function, potentially from a compromised package, accesses the key and uploads it to a third party. For this reason, when using ggmap we recommend a heightened sense of security and self-awareness: only use trusted packages, do not save API keys in script files, routinely cycle keys (regenerate

Three examples. I am going to run through three examples.

The ggmap package. Several R libraries exist to visualise spatial information. ggmap by David Kahle which aligns with the ggplot philosophy of layered visualisations. The geocode function from the ggmap package extracts longitude and latitude from Google maps, based on a location query.

Oct 13, 2017 · The two main plotting features of ggmap are the get_map() function, which downloads a map from a specified map provider, and the ggmap() function that plots the downloaded map on a ggplot plot.

The ggmap package for static maps with background tiles. The ggmap library makes it easy to retrieve raster map tiles from popular online mapping services like Google Maps, OpenStreetMap or Stamen Maps, and plot them using the ggplot2 framework. It produces static maps like these. Click on an image to get the related code snippet.

But another problem arises with your example. Since the polygon is larger than the map extent, ggmap does not correctly clip the polygon. ggmap sets the limits on the scale, this will throw away all data that’s not inside these limits. Here is a modified version of your code:

Part of the ward boundaries are beyond the map boundary. Due to the default settings in ggmap(), any data off the map is dropped before plotting, so some polygon boundaries are dropped and when the remaining points are joined up you get the wrong shapes. Don’t worry, there is a solution: ggmap() provides some arguments to control this behaviour.

ggmap builds on ggplot and allows to pull in tiled basemaps from different services, like Google Maps, OpenStreetMaps, or Stamen Maps 15. So let’s overlay the map from above on a terrain map we pull from Stamen. First we use the get_map() command from ggmap to pull down the basemap. We need to tell it the location or the boundaries of the map

In order to use ggmap we have to decompose the shapefile of polygons into something ggmap can understand (a dataframe).
