#georeference

Allmaps is a set of open source tools that make it easier and more fun to search, explore, georeference and work with collections of digitised maps

 Allmaps works with any image repository that supports the International Image Interoperability Framework (IIIF). By using tiled IIIF images, JavaScript and WebGL, Allmaps can warp georeferenced maps in the browser. This eliminates the need for running a map tile server or WMS server.

 Allmaps and its components are far from finished so this is a work in progress still, with funding from libraries in The Netherlands.
