Comparing Old Maps


The David Rumsey Map Collection is a fantastic collection of vintage maps from around the world. The David Rumsey Map Collection has also been at the forefront in working on digitizing vintage paper maps and making them available to view and use online. For a long time the collection has used Georeferencer to georectify vintage maps and make them accessible as interactive digital maps.

This year Georeferencer has released version 4 of their Georeferencer tool. The tool has added some great new features to aide anyone interested in georectifying and digitizing old vintage maps. It also has a great new interface for comparing different maps side by side.

Georeferencer Compare is an amazing way to find and compare old vintage maps side-by-side, It includes various different view modes. As well as comparing maps side-by-side you can overlay different maps as layers (and adjust their opacity), you can view them in swipe mode or you can use a 'spy glass'.

The David Rumsey Map Collection has updated to version 4 of Georeferencer. This means you can use David Rumsey Georeferencer Compare to find and compare vintage maps from the collection. Using the tool is a great way to see view how maps of specific locations have developed over time,
