deprecated: Deprecated interface
In rosm: Plot Raster Map Tiles from Open Street Map and Other Sources

as.tile_source

R Documentation

Deprecated interface

Description

The previous interface for rosm was written to support idioms that are no longer prevalent in modren r-spatial code. These functions may continue to exist; however, their use is not encouraged and the functions may be removed in a future release.

Usage

as.tile_source(x, ...)

is.tile_source(x)

source_from_url_format(
  url_format,
  max_zoom = tile.maxzoom.default(),
  min_zoom = 0,
  attribution = NULL,
  extension = tools::file_ext(url_format[1]),
  ...
)

register_tile_source(...)

set_default_tile_source(x, ...)

get_default_tile_source()

osm.types()

bmaps.types()

bmaps.plot(bbox, type = "Aerial", key = NULL, ...)

  res = 150,
  project = TRUE,
  progress = c("text", "none"),

Arguments

`x, y, x0, y0, x1, y1, url_format, max_zoom, min_zoom, attribution, extension`	Deprecated
`...`	Arguments passed to other methods
`bbox`	A bounding box as generated by `sp::bbox()`
`type`	A map type; one of that returned by osm.types. User defined types are possible by defining `tile.url.TYPENAME <- function(xtile, ytile, zoom){}` and passing TYPENAME as the `type` argument.
`key, tolatlon, epsg, toepsg, labels, n, e, s, w, factor, offset`	Deprecated
`zoomin`	The amount by which to adjust the automatically calculated zoom (or manually specified if the `zoom` parameter is passed). Use +1 to zoom in, or -1 to zoom out.
`zoom`	Manually specify the zoom level (not reccomended; adjust `zoomin` or `res` instead.
`forcedownload`	`TRUE` if cached tiles should be re-downloaded. Useful if some tiles are corrupted.
`stoponlargerequest`	By default `osm.plot` will only load 32 tiles at a time. If plotting at a higher resolution it may be necessary to pass `true` here.
`fusetiles`	`TRUE` if tiles should be fused into a single image. This is the default because white lines appear between tiles if it is set to `FALSE`. PDFs appear not to have this problem, so when plotting large, high resolution PDFs it may be faster (and more memory efficient) to use `fusetiles=FALSE`.
`cachedir`	The directory in which tiles should be cached. Defaults to `getwd()/rosm.cache`.
`res`	The resolution used to calculate scale.
`project`	`TRUE` if tiles should be projected to a pseudo-mercator projection, `FALSE` if lat/lon should be maintained. Becuase `sp::plot` adjusts the aspect according to latitude for lat/lon coordinates, this makes little difference at high zoom and may make plotting overlays more convenient. Defaults to `TRUE`.
`progress`	A progress bar to use, or "none" to suppress progress updates
`quiet`	Pass `FALSE` to see more error messages, particularly if your tiles do not download/load properly.
`projection`	A map projection in which to reproject the RasterStack as generated by `CRS()` or `Spatial@proj4string`. If a `Spatial` object is passed as the first argument, this argument will be ignored.
`crop`	`TRUE` if results should be cropped to the specified bounding box (see `x`), `FALSE` otherwise.
`filename`	A filename to which the raster should be written (see `raster::writeRaster()`). Use a ".tif" extension to write as a GeoTIFF.
`resample`	One of "ngb" (nearest neighbour) or "bilinear". Passed to projectRaster.
