wxGUI Map Swipe


       The  Map  Swipe  is  a  wxGUI component which allows the user to interactively 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:

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

           ·   zooming, panning

           ·   automatically load maps when opening Map Swipe with two selected  raster  maps  in
               Layer Manager

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

           ·   save display to graphics file

           ·   display text labels with map names

           ·   choose between  ’swipe’  mode  (default)  and  ’mirror’  mode  (synchronized  maps
               displayed side by side)

           ·   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 normal 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 Observatory/NASA
