WEAVE (Web-based Analysis and Visualization Environment) is a web-based visualization platform offered by the Institute for Visualization and Perception Research at the University of Massachusetts Lowell. It is designed to visualize any data for any purpose, and to accommodate novice and advanced users alike. It includes the ability to integrate, disseminate and visualize data at nested levels of geography. WEAVE is currently in beta. Both a web-based demo and a download version are available.

Maphub is 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.

A first prototype of Maphub, using digitized maps from the Library of Congress’ Map Division, can be found at http://maphub.herokuapp.com/.
