Real-Time VR Landscape Visualization for Wind Farm Repowering: A Case Study in Eastern Austrian World Heritage Sites

The expansion of wind energy is key for achieving the EU’s sustainable energy targets. One of the main hurdles, however, is a lack of social acceptance: Resistance against new or repowered wind farms is still common. Particularly valuable regions such as World Heritage Sites pose additional challenges, as the introduction of energy infrastructure in the vicinity of such landscapes carries the risk of losing their status. Stakeholders need objective tools to assess the impact of wind farms on a landscape. This article presents and evaluates one such tool: an interactive landscape visualization framework which allows users to view arbitrary visual axes with a virtual reality headset. Given high-quality geographic data, this visualization objectively recreates landscapes with accuracy high enough for viewers to recognize the scenery and orient themselves. It was used in three workshops as part of a case study in the Austrian federal state of Burgenland. According to the participants’ statements, the sense of scale conveyed by virtual reality technology and the perceived accuracy of the visualization allowed them to make a more informed decision on the matter. However, particularly in one transnational workshop, the lack of consistent high-quality data posed a challenge: When the visualization is deemed inaccurate, it loses its credibility and therefore its use in decision-making processes. This reinforces the call for openly accessible high-quality pan-European GIS data.
