sds: 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 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 SpatRasters, 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

extent

SpatExtent

...

additional SpatRaster objects

Examples

Run this code
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]

a <- array(1:9, c(3,3,3,3))
sds(a)
