PROV mapwarper

Stuart Thyer


The PROV Map Warper is a tool for digitally aligning ('rectifying') historical maps and plans from Public Record Office Victoria's collections to match today's precise maps. Visitors can browse already rectified maps or assist us by aligning a map.


It’s a technique probably very familiar to many light railway researchers already. Depending on the sources, I’ve used both Google Earth’s version and also Photoshop for previous work.
