The following example demonstrates the setting of a map\ntiles server and how to cache the original tiles for future use:\n\n``` r\n# define the tile server parameters\nosmpos <- create_provider(\n name = \"CARTO.POSITRON\",\n url = \"https://{s}.basemaps.cartocdn.com/light_all/{z}/{x}/{y}{r}.png\",\n sub = c(\"a\", \"b\", \"c\", \"d\"),\n citation = \"© OpenStreetMap contributors © CARTO \"\n)\n# dowload tiles and compose raster (SpatRaster)\nnc_osmpos <- get_tiles(\n x = nc, provider = osmpos, crop = TRUE,\n cachedir = tempdir(), verbose = TRUE, retina = TRUE\n)\n#> Zoom: 7\n#> Source(s): © OpenStreetMap contributors © CARTO \n#> Cache directory: /tmp/Rtmpfvd4hn/CARTO.POSITRON\n#> 8 tiles\n#> The resulting raster uses high resolution tiles.\n# display map\nplot_tiles(nc_osmpos)\n# display credits\nmtext(text = get_credit(osmpos), side = 1, line = -1, adj = .99)\n```\n\n![](man/figures/README-example2-1.png)\n\nThe following figure shows mini maps for most of the tiles providers\navailable:\n\n![](man/figures/README-front.png)\n\n## Projection\n\nOriginal tiles use a projection known as “Web Mercator”, “WGS84 / Pseudo\nMercator”, “Google Mercator”, “EPSG:3857” or “EPSG:900913”. In most\ncases `get_tiles()` uses the projection of its `x` argument to reproject\nthe tiles. If you wish to avoid any deformation induced by the\nreprojection process, use “EPSG:3857” for `x` projection.\n\n## Attribution of map tiles\n\nAll maps available through `maptiles` are offered freely by various\nproviders. The only counterpart from the user is to properly display an\nattribution text on the maps. `get_credit()` displays a short\nattribution text to add on each map using the downloaded tiles.\n\n## Alternatives\n\nThere are many alternative packages that pursue the same objective as\n`maptiles`. Some focus on a specific map tiles provider (e.g. Mapbox,\nGoogle, OpenStreetMap) or on a specific graphics device (`ggplot2`). The\ngoal of `maptiles` is to be flexible enough to allow the use of\ndifferent providers and to have a minimal number of robust and modern\ndependencies. However, depending on the use case, one of following\npackages may better suit your needs:\n\n- [`ceramic`](https://github.com/hypertidy/ceramic) \n- [`ggmap`](https://github.com/dkahle/ggmap) (`ggplot2` focused)\n- [`ggspatial`](https://github.com/paleolimbot/ggspatial) (`ggplot2`\n focused, based on `rosm`)\n- [`mapboxapi`](https://github.com/walkerke/mapboxapi) (mapbox)\n- [`mapsapi`](https://github.com/michaeldorman/mapsapi/) (google, based\n on `RgoogleMaps`)\n- [`OpenStreetMap`](https://github.com/ifellows/ROSM) (requires Java)\n- [`RgoogleMaps`](https://github.com/markusloecher/rgooglemaps) (google)\n- [`rosm`](https://github.com/paleolimbot/rosm)\n- …\n\n## Note\n\nNot to be confused with\n[`tilemaps`](https://github.com/kaerosen/tilemaps), that “implements an\nalgorithm for generating maps, known as tile maps, in which each region\nis represented by a single tile of the same shape and size.”","jobInfo":{"package":"maptiles","version":"0.9.0","parsingStatus":"success","parserVersion":2,"parsedAt":"2025-02-04T11:30:00+0000"}}
