TreeGPT: Generative Pre-trained Transformer for forestry applications with 3D point clouds
For my master's thesis, I tackled a challenge that has captured my interest for years: leveraging LiDAR point clouds to generate automated forest inventories. As of today, we still rely on largely incomplete manual forest inventories to manage the wooden third of Switzerland‘s land area. Advancements in 3D computer vision applied to LiDAR point clouds can improve that. TreeGPT leverages self-supervised training on unlabeled and synthetic point clouds of single trees and contributes to the creation of a foundation model for forestry vision tasks.

Infrastructure management along highways and railways requires inventories of critical structures like retaining walls, which traditionally relies on manual inspection and documentation. Unfortunately, data in infrastructure databases is often incomplete. In this study, we investigated the feasibility of automating retaining wall inventories using public aerial lidar data from the Swiss Federal Office of Topography (Swisstopo).

Rockfall barriers are mechanically complex systems due to the extreme dynamics of the processes involved and can behave unpredictably. To better understand the behavior of these systems, numerical simulations can be a powerful tool. However, existing commercial software solutions often come with limitations, such as high costs or lack of modelling flexibility. Therefore, as part of a student project during my master's studies, I embarked on a journey to develop a numerical simulation tool, which I named RockBarrierAnalytica (RBA).

Site builders like Wix, Squarespace, or Wordpress have made building sites easy and cheap. For those still interested in building them themselves, Platform as a Service (Paas) offerings like Vercel or Github Pages make deployments and hosting a breeze. But I wanted to grow my web development skills further so I built it from the ground up (...almost!) and deployed it on a VPS.
