For years, archaeological excavation documentation has been faced with a methodical challenge strongly related to the general digital and technical development. The acceptance and implementation of GPS, total station, CAD and GIS as a new documentation tradition, mirroring analogue documentation principles, is a perfect example of this. However, an actual seamless integration of digital, spatial data is still proving to be a challenge, especially in the light of the increasing use of 3D-documentation. GIS and CAD only partly address the needs of archaeological documentation, and file based storage imposes very high demands to the structuring and organisation of data.
By example of several Danish research excavations where different photogrammetric and 3D visualisation documentation principles were applied, this paper presents a new, browser-based, object-oriented archaeological excavation database, seeking to complement existing solutions by integrating digital spatial data. By collecting, presenting and scientifically augmenting the data quality and integrity, existing and new excavation data become far more searchable across sites. The solution integrates numerous archaeological classification systems with GIS and 3D-documentation, and include existing excavation data from national web services. In addition, the 3D-module allows for administering vertical excavation profiles and sections, and increases the value of 3D-documentation by providing automated tools for the embedding of semantic, archaeological classification within 3D models, whereby 3D-models become more dynamic information carriers, compared to static surface models.
