Dokumentation von archäologischen Blockbergungen in einem Geografischen Informationssystem (GIS)

Abstract

The Documentation of Archaeologic Block-Lifted Recovery Using a Geographic Information System (GIS)
It is more and more common to use a geographic information system (GIS) for the documentation of archaeological excavations. When treating blocklifted archaeological objects the procedure is usually similar to an excavation-en-miniature, but the documentation is mostly carried out with digital photographs and drawings instead. When using GIS it is possible to chart with vector graphics on digital, geo-referenced overview photographs. Attribute data containing more information about the depicted objects, are linked to the vector graphics. In a master thesis a concept for the documentation in GIS was developed and tested in the course of the treatment of a block-lifted recovery. Thus it was possible to check the accuracy of this method and to compare it to a hand drawn mapping. The mappings showed a high precision, but there was some distortion in the overview images caused by level differences in the planes. The technique is fast and easy to learn and to use. Because of the linked attributes the information content is higher, and the information is more easily integrated in the overall archaeological analysis.
