Create a SpatRasterDataset

Description

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.

Usage

## S4 method for signature 'missing'
sds(x, ...) 

## S4 method for signature 'character'
sds(x, ids=0, ...)

## S4 method for signature 'SpatRaster'
sds(x, ...) 

## S4 method for signature 'list'
sds(x, ...)

Arguments

`x`	character (filename), or SpatRaster, or list of SpatRaster objects, or missing. If multiple filenames are provided, it is attempted to make SpatRasters from these, and combine them into a SpatRasterDataset
`ids`	optional. vector of integer subdataset ids. Ignored if the first value is not a positive integer
`...`	additional arguments. Can be other `SpatRaster` objects if `x` is a `SpatRaster`

Value

SpatRasterDataset

Examples

s <- rast(system.file("ex/logo.tif", package="terra"))   
x <- sds(s, s/2)
names(x) <- c("first", "second")
x
length(x)

# extract the second SpatRaster
x[2]
