Abstract

One of the major problems that archaeology faces today is that the traditional (“manual”) methods of archaeological field data classification and archiving fail to meet the modern requirements in the context of accuracy and convenience. In this study, we assessed the utility of standard photogrammetry for creating excavation plans, as well as developed and tested new methods. All works were performed at the excavation sites of Bolghar, an ancient town in Tatarstan (Russia). The excavations varied in size and depth. The standard methods were found to often yield improper results for the following reasons: in useful if high-precision geodetic equipment is unavailable. Orthophotomaps are less precise than GNSS-based plans, but much more accurate than manual sketches. The results obtained during this study are important for the development of field archaeology. The recommendations given in this paper can be used by archaeologists in their daily work. Compliance with these recommendations guarantees high-precision excavation plans. It is expected that the proposed method-ology will become the basis for instructions on arrangement of archaeological excavations in the very near future.

近景摄影测量作为制定详细的全层开挖计划的参考方法
考古学面临的主要问题之一是,传统的(“手工”)考古现场数据分类和归档方法在准确性和便捷性方面已不能满足现代要求。在这项研究中,我们评估了标准摄影测量在制定挖掘计划方面的效用,并开发和测试了新方法。所有的工作都是在鞑靼斯坦(俄罗斯)的一个古镇Bolghar的挖掘现场进行的。挖掘的规模和深度各不相同。由于以下原因,发现标准方法经常产生不正确的结果:在没有高精度大地测量设备的情况下是有用的。正射影像图不如基于gnss的计划精确,但比手工草图精确得多。研究结果对野外考古的发展具有重要意义。本文提出的建议可供考古学家在日常工作中使用。遵守这些建议可以保证高精度的挖掘计划。预计在不久的将来,所提出的方法将成为安排考古发掘工作的指导依据。
