💖 wxGUI.mapswipe(1) 💖

okay so bestie, welcome to the GRASS GIS User's Manual page for wxGUI.mapswipe(1) — the lil' GUI legend that lets you swipe between maps like it's a dating app but for rasters ✨

🎀 NAME 🎀

wxGUI Map Swipe — the icon, the moment, the vibe 🦋

🌸 DESCRIPTION 🌸

okay so the Map Swipe is a wxGUI component, and what it does is let you interactively compare two raster maps of the same area by revealing different parts of the raster maps. it's giving "spot the difference" but make it cartography 💅. it's useful e.g. for comparing raster maps from different time periods. you can launch Map Swipe from the menu File -> Map Swipe.

Map Swipe lets you do all of this, no cap:

  • 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

(not me getting emotional over satellite imagery 😭 the way that the same coastline tells two completely different stories... iconic, devastating, and exactly why this tool exists 💔)
