MapHub

Maphub in a web portal for georeferencing and annotating digitized historic maps. Georeferencing transforms the map image to align with real world geographic coordinates, while the annotations are overlaps plus notes. Maphub suggests possible tags for the annotation based on its text and location; tags link to related Wikipedia articles. Once created, user-contributed annotations are shared via the Maphub Open Annotation API.
