Mixed-Reality in der Ingenieurgeologie – von der Datenaufnahme bis zum immersiven 3D-Hologramm

The rapidly advancing digitization and fast gro-wing amounts of geodata present engineering geology with new challenges. Modern devices such as drones and laser scanners produce enormous amounts of data in a short time. Preparing these data and presenting them to clients, planners or stakeholders in an understandable way are essential engineering geological tasks. Instead of using traditional maps, profile sections and static 3D models, the data can be presen-ted in more intuitive interactive, digital environments. Mixed reality applications offer new opportunities to virtually and im-mersively visit the digital twin of a project in the form of a ho-logram. Location-independent meetings in real time on holographic 3D models, without having to physically change the location, save time and enable a quick information exchange. This paper provides an overview of the workflow for genera-ting holographic data of existing projects and what to consider during collecting and processing data for new projects. Focus is laid on applications in engineering geology, and the potenti-al and limitations of this technology are elaborated.
