sites that manage location based content, like e.g. buildings or commercial entities in an areal or a city, do already have all the required information at hand which are building blocks for a way finding feature, either on-site or on external touch screens. Developing all the relationships and widgets to turn that information into a modern and reach user experience is what's needed out of the box.
This module is a generic approach to easily build way finding functionality on top of almost any content structure available on existing 8+ websites. As an option, it also work together with the Digital Signage Framework in order to use way finding on externally managed displays too.
