Get Canadian Digital Elevation Model (CDED) as a raster object

Description

Get Canadian Digital Elevation Model (CDED) as a raster object

Usage

cded_raster(
  aoi = NULL,
  tiles_50K = NULL,
  .predicate = sf::st_intersects,
  dest_vrt = tempfile(fileext = ".vrt"),
  check_tiles = TRUE,
  ...
)

Arguments

aoi

Area of Interest. Currently supports sf and sp polygons, stars and raster objects.

tiles_50K

a character vector of 1:50,000 NTS mapsheet tiles

.predicate

geometry predicate function used to find the mapsheets from your aoi. Default sf::st_intersects.

dest_vrt

The location of the vrt file. Defaults to a temporary file, but can be overridden if you'd like to save it for a project

check_tiles

Should the tiles that you already have in your cache be checked to see if they need updating? Default TRUE. If you are running the same code frequently and are confident the tiles haven't changed, setting this to FALSE will speed things up.

...

Further arguments passed on to raster::raster

Value

a raster object of the cded tiles for the specified area of interest
