Download from Digital Earth Australia

download_dea.Rd

Wrapper funtion to get the layers from Digital Earth Australia collections.

Usage

download_dea(
  layer,
  bounding_box,
  out_path,
  years,
  resolution,
  crs = "EPSG:4326",
  format_out = "GeoTIFF"
)

Arguments

layer

Layer name(s) to download as a vector of strings

bounding_box

A numeric vector of coordinate values used to generate a bounding box around are of interest in EPSG:4326 format, for example, c(min_x, min_y, max_x, max_y)

out_path

Path to an output/download folder, e.g. 'downloads/'

date_min

string Start date to download in YYYY-MM-DD, e.g. 2019-10-01

date_max

string End date to download in YYYY-MM-DD, e.g. 2019-11-01

resolution

An integer value for resolution, in arc seconds

crs

Coordinate referencing system (CRS) to use. Currently, only accepts 'EPSG:4326'

format_out

Output format, either "GeoTIFF" or "NetCDF". Defaults to "GeoTIFF"

Value

a list of filenames (after files have been downloaded or processed)
