Easily georeference maps from institutions across the world
Allmaps is a next-generation software ecosystem that makes it easier and more fun to create, curate, and share goereferenced maps. Using the International Image Operability Framework (IIIF), Allmaps can warp and display scanned maps entirely in a web browser, without the need to download desktop GIS software like ArcGIS or QGIS.
In collaboration with the Allmaps development team and the American Geographical Society Library at the University of Wisconsin-Milwaukee, the Leventhal Center leads an ongoing project focused on helping other map-holding institutions improve accessibility to their digital collections. Our focus areas include:
This work is supported by a Digital Humanities Advancement Grant from the National Endowment for the Humanities (Award HAA-293491-23). Please reach out to Ian Spangler if you want to learn more about Allmaps or get involved in the project!
|Go to application
Georeference any IIIF-compliant map, entirely in a web browser.
Open Allmaps Editor directly from any object in LMEC collections.
You can also load a map via its IIIF manifest from any IIIF-compliant digital map collection.
View any map that was georeferenced using Allmaps overlaid on a modern web map.
Load the map by pasting its IIIF manifest or georeference annotation.
Toggle transparency and even remove certain colors from the overlay map to compare how places have changed over time.
View a live feed of the latest maps georeferenced using Allmaps.
Improve maps that need better masks or more control points.
See which collections are georeferencing the most maps.
