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

35 MODIS image taken on February 26, 2011, shows the coastline under nor‐
36 mal conditions while the lower MODIS image on March 13, 2011, shows a
37 clear view of tsunami flooding along the coastline. Water, black and
38 dark blue in these false-color images, still covers the ground as much
39 as five kilometers (three miles) from the coast. Source: Earth Obser‐
