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 missing
sds(x)
# S4 method for character
sds(x, ids=0)
# S4 method for SpatRaster
sds(x, ...)
# S4 method for list
sds(x)
# S4 method for array
sds(x, crs="", extent=NULL)
Value
SpatRasterDataset
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
crs
character. Description of the Coordinate Reference System (map projection) in PROJ.4, WKT or authority:code 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
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 SpatRasterx[2]
a <- array(1:9, c(3,3,3,3))
sds(a)
