Dokumentation von archäologischen Blockbergungen in einem Geografischen Informationssystem (GIS)

Abstract

It is increasingly more common to use GIS for the documentation of archaeological excavations. When treating block-lifted archaeological objects, the procedure is usually similar to an excavation in miniature and it is also possible to produce plans using vector graphics on digital, georeferenced overview photographs. Data on attributes, which could contain more information about the depicted objects, are linked to the vector graphics. The concept developed for a documentation in GIS and two examples of its use are presented. The precision of this method was checked and compared with a plan drawn by hand. It turned out that documenting with GIS had a high degree of precision, but partly there was a distortion in the overview images caused by level differences in the plana. Altogether the technique was fast and easy to learn and to use. Because of the linked attributes, the information content is considerable and it is easier to integrate the information in the overall archaeological analysis.
