Integration of Geomatic Techniques for the 3d Representation and Monitoring of a Veteran Chestnut Tree

Abstract

Abstract. This study concerns the application of different geomatic techniques in forestry sector. An accurate 3D model of a veteran chestnut tree (Castanea sativa Mill.) has been realised integrating point clouds by Mobile Laser Scanner (MLS) and photogrammetry techniques. The surveys were conducted in two seasons (summer time: July 22nd 2021; autumn time: December 10th 2021), since chestnut is a deciduous tree and thus taking the chance to detect it also without leaves. Therefore, it was obtained tree’s metric data such as the diameter at breast height (DBH), the total height (TH), the crown basal area, the wood and crown volume. Annual surveys will result in a dataset of virtual trees that will be used to monitor the evolution of these noteworthy plants through time, which are expected to be considered as cultural heritage, given their story and their importance at regional and landscape level. The 3D model was then released for virtualization, making it accessible and available as a data container for different users. Such data will also provide historical memory about the presence of these veteran trees that might be lost in the future if affected by species-specific phytopathologies such as Ink Disease (Phytophthora spp.).

“…To this end, modern measurement technologies should be used to obtain a digital version of the surrounding world quickly and accurately. We can find examples of such activities (localisation and quantity) in [11,15,17,99,100]. As for the quality aspect, confirmation of the validity of this thesis can be found in [101][102][103][104][105].…”

“…LiDAR laser scanning can be used both for inventory measurements, describing reality as presented in papers [11,12], as well as for long-term activities, i.e., monitoring [13,14]. In environmental issues, there is often a need to use multi-source data, examples of which can be found in papers [15][16][17][18]. Data integration also occurs in the area of cultural heritage, examples of which can be found in papers [19,20].…”
