The systematic evaluation of accessibility to different sectors in caves with Palaeolithic rock art is crucial to interpret the contexts of prehistoric human activity that took place inside them, especially if focused on the areas that are harder to reach. 3D models have been employed in a GIS to process spatial information, calculate numerical cost values and estimate optimal transit routes or needed times to reach several sectors inside a cave, based on morphological features and movement types. These have been obtained through empirical observations and experimental archaeology. Previous geomorphological studies are necessary to determine any geological or anthropic changes that may have occurred in the endokarst since its use in the Upper Palaeolithic. The method has been applied in Atxurra Cave, with satisfactory results, and the accessibility to different archaeological sectors has been compared objectively. This will enable the objective and quantitative assessment of accessibility to the deep sectors of other prehistoric caves in the future, and thus establish recurring or specific patterns among the human groups that created the Ice Age art.

用旧石器时代的岩画对洞穴中不同区域的可及性进行系统的评估，对于解释其中发生的史前人类活动的环境至关重要，特别是如果重点放在难以到达的区域时，这一点至关重要。GIS中已采用3D模型来处理空间信息，计算数值成本值并根据形态特征和运动类型估算到达山洞内多个区域的最佳运输路线或所需时间。这些都是通过经验观察和实验考古学获得的。以前的地貌学研究对于确定自从其在上旧石器时代使用以来的内岩溶可能发生的任何地质或人类变化都是必要的。该方法已在Atxurra洞穴中应用，取得了令人满意的结果，客观地比较了不同考古部门的可及性。这将能够在未来进行客观和定量的评估，以了解其他史前洞穴深层区域的可及性，从而在创造冰河时期艺术的人类群体中建立反复出现的或特定的模式。
