As our cities continue to grow and evolve, the subsurface has become an increasingly important resource that requires careful consideration in any construction planning. Bart Jannink, an experienced FME user in subsurface exploration and analysis, will showcase how FME can be used to gain deeper insights into the subsurface for the municipality of Utrecht. In this presentation, Bart will demonstrate how FME can be used to create 3D visualizations and cross-sections to gain insight into the subsurface. He will also showcase how subsurface data can be used to identify optimal routes for new pipes or infrastructure, helping to optimize construction planning and minimize disruptions. Additionally, Bart will demonstrate how FME can be used to find space for new trees. If you're interested in unlocking the potential of the subsurface for your construction projects, this presentation is for you. Bart will guide you through the possibilities of using FME to inform decision-making and provide valuable insights. Don't miss this opportunity to learn from an expert and discover the full potential of FME in subsurface exploration and analysis.
