This research was focused on the study of visual exposure evolution in the locality of the Drátenická skála nature monument (in the Czech Republic) and the surrounding forest complex in terms of history and through modelling for further possible stand development. The local forests underwent conversion from a natural fir-beech composition to an intensive spruce monoculture with few insect pests or windbreak events to an actual bark beetle infestation. Historic maps, landscape paintings, photographs, and orthophotos served as the basic materials for the illustration of the past situation. Further development was modelled using canopy height models and spectral properties captured by unmanned aerial vehicles (UAVs). As an example, the possible situation of total mortality among coniferous spruce trees after a bark beetle outbreak was modelled. Other options and a practical use of such preprocessed data are, for example, a model for opening and transforming the stands around the rock as one of the ongoing outcrop management trends in the protected landscape area (PLA) of Žďárské vrchy.

基于树冠高度模型和无人机获取的光谱信息的森林疾病暴发模拟背景下的岩石露头视觉暴露

这项研究的重点是根据历史并通过建模来进一步发展林分，研究Drátenickáskála自然纪念碑（捷克共和国）和周围森林群附近的视觉曝光演变。当地的森林经历了从天然的杉木-山毛榉组成到集约型云杉单一栽培的转变，很少有害虫或风灾事件，甚至没有发生真正的树皮甲虫侵扰。历史地图，山水画，照片和正射影像是说明过去情况的基本资料。使用冠层高度模型和无人飞行器（UAV）捕获的光谱特性对进一步开发进行了建模。例如，对树皮甲虫暴发后针叶云杉树中总死亡率的可能情况进行了建模。
