Methods to create a SpatRasterCollection. This is an object to hold a collection (list) of SpatRasters. There are no restrictions on the similarity of the SpatRaster geometry.

They can be used to combine several SpatRasters to be used with merge or mosaic

You can create a SpatRasterCollection from a file with subdatasets.

Usage

# S4 method for class 'character'
sprc(x, ids=0, opts=NULL, raw=FALSE, noflip=FALSE, guessCRS=TRUE, domains="") 

# S4 method for class 'SpatRaster'
sprc(x, ...) 

# S4 method for class 'list'
sprc(x) 

# S4 method for class 'missing'
sprc(x)

Arguments

x

SpatRaster, list with SpatRasters, missing, or filename

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

noflip

logical. If TRUE, a raster (e.g. JPEG image) that is not georeferenced and that GDAL assigns a flipped extent to (ymax < ymin), is not considered flipped. This avoids the need to flip the raster vertically

guessCRS

logical. If TRUE and the the file does not specify a CRS but has an extent that is within longitude/latitude bounds, the longitude/latitude crs is assigned to the SpatRaster

domains

character. Metadata domains to read (see metags to retreive their values if there are any. "" is the default domain

...

additional SpatRasters

Value

SpatRasterCollection

x <- rast(xmin=-110, xmax=-50, ymin=40, ymax=70, ncols=60, nrows=30)
y <- rast(xmin=-80, xmax=-20, ymax=60, ymin=30)
res(y) <- res(x)
values(x) <- 1:ncell(x)
values(y) <- 1:ncell(y)
