`basemaps` is a lightweight `R` package to download and cache spatial basemaps from open sources such as *OpenStreetMap*, *Stamen*, *Stadia*, *Thunderforest*, *Carto*, *Mapbox*, *Esri*, *Maptiler* and others. Retrieved basemaps are translated into and returned as classes of choice, such as `terra`, `stars`, `raster`, `ggplot`, `mapview`, `magick`, or as files, such as `png` or `geotif`. The package aims to ease the use of basemaps in different contexts by providing a function interface as minimalist as possible.
## Installation
Install the latest stable release of `basemaps` from CRAN:
```r
install.packages("basemaps")
```
Install the latest development version of `basemaps` from GitHub:
```r
devtools::install_github("16EAGLE/basemaps")
```
## Get started
All available map services and map types can be printed using `get_maptypes()`. The `basemap()` function and its class-specific aliases facilitate (down)loading a basemap and returning it as a class of choice. Map preferences that should be used during a session can be set as defaults using `set_defaults()`.
``` r
library(basemaps)
data(ext)
# or use draw_ext() to interactively draw an extent yourself
# view all available maps
get_maptypes()
# set defaults for the basemap
set_defaults(map_service = "osm", map_type = "topographic")
# load and return basemap map as class of choice, e.g. as image using magick:
basemap_magick(ext)
#> Loading basemap 'topographic' from map service 'osm'...
```
``` r
# or as plot:
basemap_plot(ext)
# or as ggplot2:
basemap_ggplot(ext)
# or as ggplot2 layer:
library(ggplot2)
ggplot() +
basemap_gglayer(ext) +
scale_fill_identity() +
coord_sf()
```
``` r
# or as mapview:
basemap_mapview(ext)
```
``` r
# or as spatial classes, such as raster:
basemap_raster(ext)
# or terra:
basemap_terra(ext)
# or stars:
basemap_stars(ext)
# or return files, e.g. geotif
basemap_geotif(ext)
#> [1] "basemap_20220922214954.tif"
# or png:
basemap_png(ext)
#> [1] "osm_topographic_bg_2022-09-22_12-00-00.png"
```
## Map examples
`basemaps` supports a variety of map services and types (which can be printed using `get_maptypes()`). A selection of available map types is shown below. For a complete table of available map types, see [supported services and maps](#supported-services-and-maps).

## Supported services and maps
This table lists all currently implemented map services and map types and indicates whether they can be used without a map token (requiring registration at the respective service) or not. As of the date of implementation, all map services requiring registration offer their maps for free (please refer to the respective services' terms of use for details).

## Available functions
* `get_maptypes()` returns every supported map service and map type that can be used as input to the `map_service` and `map_type` arguments of `set_defaults()`, `basemap()` or associated functions.
* `draw_ext()` lets you draw an extent on an interactive map.
* `set_defaults()`, `get_defaults()` and `reset_defaults()` set, get or reset the defaults of all map arguments passed to `basemap()` or associated functions.
* `basemap()` and its aliases `basemap_raster()`, `basemap_stars()`, `basemap_mapview()`, `basemap_plot()`, `basemap_ggplot()`, `basemap_gglayer()`, `basemap_magick()`, `basemap_png()` and `basemap_geotif()` (down)load and cache a basemap of a defined extent `ext`, `map_service` and `map_type` and return it as an object of the defined class.
* `gg_raster()` plots objects of class `SpatRaster`, `RasterLayer`, `RasterBrick` or `RasterStack` as `ggplot2`.
* `flush_cache()` deletes all cached map tiles and basemaps.
## Related packages
If you are interested in obtaining basemaps, you also may want to have a look at [`ceramic`](https://github.com/hypertidy/ceramic), an R package developed by Michael Sumner with a similar goal.
The underpinning code of `basemaps` was originally developed for [`moveVis`](https://movevis.org) and has been detached to allow its general use.
