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, opts=NULL, raw=FALSE)
# 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
opts
character. GDAL dataset open options
raw
logical. If TRUE, scale and offset values are ignored
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)
