Diachronic studies play a key role in the research and documentation of cultural heritage and its changes, ranging from architectural fragments to landscape. Regarding the reconstructions of lost cultural heritage sites, the determination of landscape conditions in the reconstructed era goes frequently unheeded. Often, only ruins and detached archeological artefacts remain of the built heritage. Placing them correctly within the reconstructed building complex is of similar importance as placing the lost monument in the context of the landscape at that time. The proposed method harmonizes highly heterogeneous sources to provide such a context. The solution includes the fusion of referential terrain models of different levels of detail (LODs) as well as the fusion of diverse 3D data sources for the reconstruction of the built heritage. Although the combined modeling of large landscapes and small 3D objects of a high detail results in very large datasets, we present a feasible solution, whose data structure is suitable for Geographic Information Systems (GIS) analyses of landscapes and also provides a smooth and clear 3D visualization and inspection of detailed features. The results are demonstrated in the case study of the island monastery, the vanished medieval town of Sekanka, and the surrounding landscape, which is located in Czechia and was the subject of intensive changes over time.

失落的文化遗产地和景观的重建：时空古物的语境

历时性研究在文化遗产及其变化（从建筑碎片到景观）的研究和文献记录中起着关键作用。关于丢失的文化遗产遗址的重建，重建时代的景观条件确定常常被忽视。通常，遗迹和独立的考古文物仅保留在已建遗产中。将它们正确地放置在重建的建筑群中，其重要性与当时将丢失的纪念碑放置在景观环境中的重要性相似。所提出的方法协调了高度异构的源以提供这种环境。该解决方案包括融合不同详细程度（LOD）的参考地形模型，以及融合多种3D数据源以重建建筑遗产。尽管大型景观和高细节小3D对象的组合建模会产生非常大的数据集，但我们提出了一种可行的解决方案，其数据结构适用于景观的地理信息系统（GIS）分析，并且还提供了平滑清晰的3D可视化和检查详细功能。结果显示在岛修道院，消失的中世纪城镇Sekanka以及周围景观的案例研究中，该景观位于捷克共和国，是随时间推移发生剧烈变化的主题。其数据结构适用于地理信息系统（GIS）的景观分析，还可以提供平滑清晰的3D可视化和详细特征的检查。结果显示在岛修道院，消失的中世纪城镇Sekanka以及周围景观的案例研究中，该景观位于捷克共和国，是随时间推移发生剧烈变化的主题。其数据结构适用于地理信息系统（GIS）的景观分析，还可以提供平滑清晰的3D可视化和详细特征的检查。结果显示在岛修道院，消失的中世纪城镇Sekanka以及周围景观的案例研究中，该景观位于捷克共和国，是随时间推移发生剧烈变化的主题。
