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
