3D digital recording technologies have become increasingly popular for rapid, cost-effective, and accurate archaeological documentation in the field. Despite improvements in 3D GIS software, three-dimensional reconstruction of archaeological stratigraphy has been slow to develop and is rarely utilized as a basis for spatial analysis post-excavation. This is partially owing to the technical and methodological challenges of creating accurate reconstructions of excavated stratigraphy, which restricts the analytical potential of 3D datasets. Volumetric 3D modeling could vastly improve how we understand and analyze archaeological deposits and stratigraphies by enabling a quantitative comparative analysis of per-volume density of artifact types between stratigraphic units.

The presented case study examines the spatial articulation of the recorded stratigraphic units from three adjacent trenches excavated during the 2015–2017 field season at the Chalcolithic settlement site of Chlorakas-Palloures in Cyprus. Three vector-based 3D modeling methods using the existing 3D Analyst toolkit within the proprietary software ESRI ArcScene are evaluated for their effectiveness in volumetric representation of stratigraphy using total station (TS) data and photogrammetry models of archaeological features.

The results of this study indicate that volumetric modeling can enhance the analytical potential of spatial data by visualizing and identifying patterns in excavated deposits and organizing and disseminating information about the excavation process in an intuitive, user-friendly interface. However, accurate volumetric modeling of all types of archaeological features requires a re-evaluation of conventional documentation procedures to capture the volume of excavated deposits rather than just the interfaces between them. Furthermore, efficient workflows using cost-effective and open source software must be developed to make this approach more accessible and effective for a wider archaeological community.

体积3D建模在考古地层分析中的潜力和问题:以塞浦路斯Chlorakas- Palloures为例

3D数字记录技术在该领域中快速,经济高效且准确的考古记录文件已变得越来越流行。尽管对3D GIS软件进行了改进,但考古地层的三维重建工作进展缓慢,很少被用作挖掘后空间分析的基础。这部分归因于创建精确的挖掘地层重建技术和方法上的挑战,这限制了3D数据集的分析潜力。体积3D建模可以通过对地层单位之间的文物类型的每体积密度进行定量比较分析,从而极大地改善我们对考古沉积物和地层的理解和分析方式。

本案例研究研究了塞浦路斯Chlorakas- Palloures的Chalcolithic沉降点在2015-2017田间季节开挖的三个相邻沟槽中记录的地层单元的空间清晰度。使用全站仪(TS)数据和考古特征摄影测量模型,评估了使用专利软件ESRI ArcScene中现有的3D Analyst工具包的三种基于矢量的3D建模方法在地层体积表示中的有效性。

这项研究的结果表明,体积建模可以通过可视化和识别出开挖矿床的模式以及在直观,用户友好的界面中组织和传播有关开挖过程的信息来增强空间数据的分析潜力。但是,对所有类型的考古特征进行准确的体积建模都需要重新评估传统的文档记录程序,以捕获挖掘出的沉积物的体积,而不仅仅是它们之间的界面。此外,必须开发使用具有成本效益的开源软件的高效工作流程,以使这种方法对于更广泛的考古界更易于访问和有效。
