In the management discipline of Enterprise Architecture, visualisations already are a standard instrument to provide decision support. Yet visualisations of information, particularly within the field of System Cartography, might reach vast dimensions. To analyse such large graphics and benefit from the illustrated information, efficient means of navigation are essential. Nevertheless, sophis- ticated concepts covering graphical interaction are still rare. Few research or open source components addressing the growing need for functionality which eases the handling of big graphics can be found.
The following work presents design and implementation of an approach to tackle the problem of providing commonly needed navigation mechanisms on Enterprise Architecture visualisations. The implementation is based on an existing web-based Enterprise 2.0 framework enabling collaborative data col- lection and maintenance in an organisation.
