Ing. Marek Hrdina is currently pursuing postgraduate studies in the realm of forest management and remote sensing. His primary focus lies in close-range photogrammetry. Having completed both bachelor's and master's degrees by the year 2021, his educational journey was dedicated to forestry. This educational background paved the way for collaborative research and postgraduate studies at the Department of Forest Management at the CULS. Marek has engaged in various projects, each addressing distinct aspects of forestry or arboriculture. These projects have involved detecting forest height increments from airborne data, estimating timber volume by remote sensing, conducting forest inventories through mobile phone photography, employing deep learning methods for identifying decay in tree stems, and intricately reconstructing individual trees for in-depth analysis.
