Get BOM radar imagery

Fetch BOM radar imagery from ftp://ftp.bom.gov.au/anon/gen/radar/ and return a raster layer object. Files available are the most recent radar snapshot which are updated approximately every 6 to 10 minutes. Suggested to check file availability first by using get_available_radar.

get_radar_imagery(product_id, path = NULL, download_only = FALSE)

Arguments

product_id	Character. BOM product ID to download and import as a raster object. Value is required.
path	Character. A character string with the name where the downloaded file is saved. If not provided, the default value NULL is used which saves the file in a temp directory.
download_only	Logical. Whether the radar image is loaded into the environment as a raster layer, or just downloaded.

Value

A raster layer based on the most recent .gif' \acronym{radar} image snapshot published by the \acronym{BOM}. If \code{download_only = TRUE} there will be a NULL` return value with the download path printed in the console as a message.

Details

Valid BOM Radar Product IDs for radar imagery can be obtained from get_available_radar.
