Many important Cultural Heritage sites have been studied over long periods of time by different means of technical equipment,
methods and intentions by different researchers. This has led to huge amounts of heterogeneous "traditional" datasets and formats.
The rising popularity of 3D models in the field of Cultural Heritage in recent years has brought additional data formats and makes it
even more necessary to find solutions to manage, publish and study these data in an integrated way.
The MayaArch3D project aims to realize such an integrative approach by establishing a web-based research platform bringing spatial
and non-spatial databases together and providing visualization and analysis tools. Especially the 3D components of the platform use
hierarchical segmentation concepts to structure the data and to perform queries on semantic entities. This paper presents a database
schema to organize not only segmented models but also different Levels-of-Details and other representations of the same entity. It is
further implemented in a spatial database which allows the storing of georeferenced 3D data. This enables organization and queries
by semantic, geometric and spatial properties. As service for the delivery of the segmented models a standardization candidate of the
OpenGeospatialConsortium (OGC), the Web3DService (W3DS) has been extended to cope with the new database schema and
deliver a web friendly format for WebGL rendering. Finally a generic user interface is presented which uses the segments as
navigation metaphor to browse and query the semantic segmentation levels and retrieve information from an external database of the
German Archaeological Institute (DAI).
