x

Satellite object.
y

extent object.
subset

Logical; if TRUE (default), all layers but the cropped ones are being dropped; if FALSE, cropped layers are appended to the Satellite object.
snap

Direction towards which to align the extent as character. Available options are "near" (default), "in" and "out" (see alignExtent).

sat <- satellite(files)

## geographic extent of georg-gassmann-stadium (utm 32-n)
ext_ggs <- raster::extent(484015, 484143, 5627835, 5628020)

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

plot(sat)
plot(sat_ggs)

## End(Not run)
