Swiping in QGIS

Tuesday, 27 September, 2016

I quite often find myself compare two images or a vector layer overlying a raster layer and, for me, a swiping tool is tremendously helpful in doing this. Its now also commonly deployed as a javascript tools in web browsers to compare before/after images as well. ERDAS Imagine has had such a function since the year dot. So it was disappointing to see that it isn’t natively part of QGIS - but heck, it is one of those nice-to-have bells and whistles. But actually, it turns out that the MapSwipeTool does just this - although its classed as an “experimental” plugin so you need to make sure these are loaded into the plugins (just change the plugin settings).

Once installed, select the swipe layer and start the plugin. This will then be revealed/hidden from the underlying layers.
