extend: Extend a Satellite object

In environmentalinformatics-marburg/satellite: Handling and Manipulating Remote Sensing Data

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.

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)

## End(Not run)
