ROSM: Open Street Map tiles in R

Codecov test coverage

Download and plot Open Street Map,Bing Maps, and other tiled map sources. A previous version of this package provided an API for plotting base maps; the new API is more low-level and covers tile math, URL generation, and fetching tiles in parallel.

Installation

The rosm package is available on CRAN, and can be installed using install.packages("rosm").

Example

library(rosm)

bounds <- wk::rct( -7476083, 5349058, -6594103, 6243203, crs = osm_crs_native() )

(grd <- osm_raster(bounds, osm_url_spec_example())) #> <wk_grd_rct [768 x 768] => [-7514066 5322463 -6574807 6261721] with crs=EPSG:3857> #> List of 2 #> $ data: 'nativeRaster' int [1:768, 1:768] -2108502 -2108502 -2108502 -2108502 -2108502 -2108502 -2108502 -2108502 -2108502 -2108502 ... #> $ bbox: wk_rct[1:1] [-7514066 5322463 -6574807 6261721] #> - attr(*, "class")= chr [1:2] "wk_grd_rct" "wk_grd" plot(grd)
