DESCRIPTION
       The  Map	 Swipe	is a wxGUI component which allows the user to interac-
       tively compare two raster maps of the same area by revealing  different
       parts  of the raster maps.  It is useful	e.g. for comparing raster maps
       from different time periods.  Map Swipe can be launched from  the  menu
       File -> Map Swipe.

       Map Swipe allows	you to:

	   o   switch orientation of the swipe line (horizontal	or vertical)

	   o   zooming,	panning

	   o   automatically  load  maps  when	opening	Map Swipe with two se-
	       lected raster maps in Layer Manager

	   o   compare 2 raster	maps or	load different combinations of	raster
	       and vector maps and set transparency (advanced mode)

	   o   save display to graphics	file

	   o   display text labels with	map names

	   o   choose  between	'swipe'	mode (default) and 'mirror' mode (syn-
	       chronized maps displayed	side by	side)

	   o   change the appearance of	cursor in 'mirror' mode	(available  in
	       Map Swipe settings)
       Pre and post disaster images of the tsunami in Japan in 2011. The upper
       MODIS image taken on February 26, 2011, shows the coastline under  nor-
       mal  conditions	while the lower	MODIS image on March 13, 2011, shows a
       clear view of tsunami flooding along the	coastline.  Water,  black  and
       dark  blue in these false-color images, still covers the	ground as much
       as five kilometers (three miles)	from the coast.	 Source: Earth	Obser-
