Abstract Visibility has been the subject of study in Palaeolithic rock art research ever since the discovery of Altamira Cave in 1879. Nevertheless, until now, the different approaches have been based on subjective assessments, due to computational limitations for a more objective methodology. Nowadays, cutting-edge technologies such as GIS allow us to address spatial studies in caves and overcome their geomorphologically complex and closed characteristics. Here we describe an innovative methodology that uses computing tools available to any researcher to study the viewsheds of the graphic units in decorated caves. We have tested its validity on the recently discovered rock art ensemble of Atxurra Cave, in Northern Spain. We demonstrate that this technology (GIS), widely used in other fields of archaeology, especially in outdoor studies, is also useable in caverns, taking into account the complex morphologies -ceilings and diverse floor-levels, for example. These programmes have also allowed us to consider the lighting systems used by the prehistoric groups inside the cave, as well as various data previously estimated by other authors, such as the height of individuals during the European LUP. The dynamism of these tools −2.5D-, as well as the advancement of new 3D GIS technologies, will allow in the future remarkable progress in these types of structural studies for a better understanding of Palaeolithic cave art phenomena.

Atxurra Cave(西班牙北部)中的隐藏图像:地下环境中旧石器时代岩石艺术可见性分析的新提议

摘要 自 1879 年阿尔塔米拉洞穴被发现以来,可见性一直是旧石器时代岩石艺术研究的主题。然而,直到现在,不同的方法一直基于主观评估,由于计算限制更客观的方法。如今,GIS 等尖端技术使我们能够解决洞穴中的空间研究,并克服其地貌复杂和封闭的特征。在这里,我们描述了一种创新方法,该方法使用任何研究人员都可以使用的计算工具来研究装饰洞穴中图形单元的视域。我们已经在西班牙北部最近发现的 Atxurra Cave 岩石艺术合奏中测试了它的有效性。我们证明了这项技术 (GIS) 广泛应用于考古学的其他领域,尤其是在户外研究中,也可用于洞穴,考虑到复杂的形态——例如天花板和不同的楼层。这些程序还使我们能够考虑洞穴内史前群体使用的照明系统,以及其他作者先前估计的各种数据,例如欧洲 LUP 期间个体的身高。这些工具的活力 -2.5D- 以及新 3D GIS 技术的进步,将在未来这些类型的结构研究中取得显着进展,以便更好地了解旧石器时代洞穴艺术现象。以及其他作者先前估计的各种数据,例如欧洲 LUP 期间个体的身高。这些工具的活力 -2.5D- 以及新的 3D GIS 技术的进步,将在未来这些类型的结构研究中取得显着进展,以便更好地了解旧石器时代洞穴艺术现象。以及其他作者先前估计的各种数据,例如欧洲 LUP 期间个体的身高。这些工具的活力 -2.5D- 以及新的 3D GIS 技术的进步,将在未来这些类型的结构研究中取得显着进展,以便更好地了解旧石器时代洞穴艺术现象。
