Get BOM Satellite GeoTIFF Imagery

Fetch BOM satellite GeoTIFF imagery from ftp://ftp.bom.gov.au/anon/gen/gms/ and return a raster SpatRaster object of 'GeoTIFF' files. Files are available at ten minutes update frequency with a 24 hour delete time. It is suggested to check file availability first by using get_available_imagery.

get_satellite_imagery(product_id, scans = 1, cache = FALSE)

Arguments

product_id	Character. BOM product ID to download in 'GeoTIFF' format and import as a `SpatRaster` object. A vector of values from `get_available_imagery` may be used here. Value is required.
scans	Numeric. Number of scans to download, starting with most recent and progressing backwards, e.g., 1 - the most recent single scan available , 6 - the most recent hour available, 12 - the most recent 2 hours available, etc. Negating will return the oldest files first. Defaults to 1. Value is optional.
cache	Logical. Store image files locally for later use? If `FALSE`, the downloaded files are removed when R session is closed. To take advantage of cached files in future sessions, use `cache = TRUE`. Defaults to `FALSE`. Value is optional.

Value

A SpatRaster object of GeoTIFF images with layers named by BOM Product ID, timestamp and band.

Details

Valid BOM satellite Product IDs for use with product_id include:
