For interested volunteers, 2256 different maps and plans of towns and fortifications from three centuries are available for geographical localization. Matching points on old and present-day maps are identified online. The old maps are automatically rectified and can then be more easily compared with other map material.

Following last year's successful georeferencing project “Prachtsatlanten”, the new participatory project spans the period from the 16th to the 18th century. The digitized maps are available alongside the complete atlases in the “Prachtsatlanten” collection on the e-rara platform.

The project is part of the Zurich Central Library's strategic focus on Citizen Science.



Introduction

Geographically locating a map with “Georeferencer” on the Old Maps Online web platform is intuitive and usually requires no prior specialist knowledge. Volunteers compare an old map with a modern map and mark points that they can identify on both: Depending on the scale of the map, suitable points include settlements, striking details of coastlines, islands, the mouths of watercourses and outlets from lakes.

In addition to a short video tutorial, you will find instructions on the most important steps. On the web platform you will also find an overview of all georeferenced maps from the ZB holdings.

Abundance and increasing accuracy

The map material is characterized by a surprising diversity: On the one hand, there are richly decorated, magnificently colored maps from large-format atlases. On the other hand, there are simpler maps that became increasingly accurate in the 18th century. The less representative use of the maps, for example as school atlases, and the smaller format of the volumes replaced elaborate map decoration. The space depicted is also varied: from world maps and maps of dominions to city and fortification plans, there is a wealth of material to suit every taste.

Two of the most magnificent atlases are unique: these “Atlas factices” combine maps, plans and illustrations that were bound together at the request of previous owners.

Tricky puzzles need to be cracked and difficult cases solved: In addition to the still rather imprecise maps of the 16th century, these include impressive plans of imposing city fortifications from the 17th and 18th centuries.
