Visual Understanding Environment (VUE) is a free, open source application for mapping concepts, ideas and digital content. It enables users to generate nodes and links, and apply a simple set of tools to explore the relationships. VUE is, in the words of its developers, an application to "integrate, organize and contextualize electronic content" in research or learning environments. Its tools include visualization, dynamic content mapping, semantic mapping, enhanced pathways and search functions.

A suite of products developed for web designers that may be used to convert large images into a form that can be zoomed and panned. Zoomify enables large images to be viewed and manipulated, without an increase in server load or download time. It converts large images stored in raster formats (e.g. TIFF, JPEG) into a set of pieces or 'tiles' The individual pieces contain sub-sections of the image at different resolutions or levels of zoom, which are combined to create a type of mosaic.

Features:

Enables access to high quality still images without an increase in server load

Modest Maps is a small Javascript library for interactive tile-based maps that can display maps from external sources (e.g. OpenStreetMap, but not commercial layers like Google Maps), enable panning and zooming, and track the position of points based on XML data. It is designed to be lightweight and offer a minimal set of features, and therefore has less functionality than Leaflet, a similar tool.
