Methods to create a SpatRasterDataset. This is an object to hold "sub-datasets", each a SpatRaster that in most cases will have multiple layers.
See describe
for getting information about the sub-datasets present in a file.
# S4 method for missing
sds(x) # S4 method for character

# S4 method for SpatRaster

# S4 method for array

SpatRasterDataset
character (filename), or SpatRaster, or list of SpatRasters, or missing. If multiple filenames are provided, it is attempted to make SpatRasters from these, and combine them into a SpatRasterDataset
optional. vector of integer subdataset ids. Ignored if the first value is not a positive integer
character. GDAL dataset open options
logical. If TRUE
, scale and offset values are ignored

notation. If this argument is missing, and the x coordinates are within -360 .. 360 and the y coordinates are within -90 .. 90, longitude/latitude is assigned
