R: Extend a Satellite object

extend {satellite} | R Documentation

## Extend a Satellite object

### Description

The function is a wrapper around `extend` to easily extend a Satellite object to a larger spatial extent.

### Usage

    ## S4 method for signature 'Satellite'
    extend(x, y, subset = TRUE, value = NA)

### Arguments

`x` | Satellite object.
`y` | Target `Extent`, see `extent`.
`subset` | Logical. If `TRUE` (default), all layers but the extended ones are being dropped, else the extended layers are appended to the initial Satellite object.
`value` | Fill value assigned to new cells passed to `extend`, defaults to `NA`.

### Value

A Satellite object consisting of extended layers only or, if `subset = FALSE`, a Satellite object with the extended layers appended.

### See Also

### Examples

    ## Not run:
    ## sample data
    path <- system.file("extdata", package = "satellite")
    files <- list.files(path, pattern = glob2rx("LC08*.TIF"), full.names = TRUE)
    sat <- satellite(files)

    ## geographic extent of georg-gassmann-stadium (utm 32-n)
    ext_ggs <- raster::extent(482606.4, 482781.4, 5627239, 5627489)

    ## extend satellite object by specified extent
    sat_ggs <- extend(sat, ext_ggs)

    plot(sat)
    plot(sat_ggs)
