extend: 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 Satellite
extend(x, y, subset = TRUE, value = NA)

Value

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

x

Examples

if (FALSE) {
## 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)
