wxGUI Map Swipe
DESCRIPTION
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
