The present challenge to preserve cultural heritage, dealing with the rise of new technological advances in terms of spatial data gathering, led to the massive surge of digital content and more than anything, to 3D models. These models, supporting analysis and valuation in archeology, architecture, cultural heritage and furniture design, are often gathered within huge databases. The core question of this presentation concerns the optimal strategy for its distribution and the specific methods involved to access and navigate through its heterogeneous data system. This paper also describes our KIVI1 hardware and software platform for immersive visualization, defining an original easy-to-use data crawling approach, optimizing its dissemination and exploitation through diverse cultural heritage digital content.
