This paper reports on the progress in the field of total viewshed computation, which was made by the joint efforts of several Slovak and Czech research institutions. The result of the project is eight total viewsheds calculated for the whole territory of Bohemia (57,000 km2) with a relatively high resolution (grid from 5 × 5 to 320 × 320 m, visibility radii from 0.5 to 64 km). Through the principal component analysis, the viewsheds were further processed and derived datasets were created defining the most important gradients of visual affordances of the Bohemian landscape. On a sample of archaeological sites (barrow cemeteries from a part of South Bohemia), it was examined how the resulting models could be interpreted and whether the identified visibility gradients affected people's behaviour in the past, namely the location of their funerary monuments. On the one hand, this study shows that non-random relationships of this type existed, but on the other hand, visibility itself may not always have been the only (or the main) factor in past behaviour, even if it is related to above-standard places in terms of visibility. All total-viewshed datasets are made available for further research through public repository.

本文报告了由斯洛伐克和捷克几家研究机构共同努力完成的全视域计算领域的进展。该项目的结果是针对波希米亚全境（57,000 平方公里）计算出的八个总视域，具有相对较高的分辨率（网格从 5 × 5 到 320 × 320 m，能见度半径从 0.5 到 64 km）。通过主成分分析，对视域进行了进一步处理，并创建了派生数据集，定义了波西米亚景观中最重要的视觉可供性梯度。在考古遗址样本（来自南波希米亚一部分的手推车墓地）上，研究了如何解释生成的模型，以及确定的能见度梯度是否影响了人们过去的行为，即他们的墓地的位置。一方面，这项研究表明存在这种类型的非随机关系，但另一方面，可见性本身可能并不总是过去行为的唯一（或主要）因素，即使它与上述有关- 能见度方面的标准场所。所有总视域数据集都可通过公共存储库进行进一步研究。
