Technical Demo: Building Digital Twins with Reality Capture and GIS


Jump-start a digital twin of your infrastructure project by using a complete drone mapping workflow. In this technical presentation, view a demonstration of how the Taiwan Fishery Agency used reality capture to build a digital twin of the Badouzi Fishing Port to plan future port development and mitigate the impact of rising sea level.

Key takeaways


Creating digital twins starts with data capture. Here are four steps to complete a reality capture workflow:
 

  • Data capture and integration—Drone technology helps collect information.

  • Real-time information and visualization—Explore what you've captured and make it understandable for stakeholders, often by using dashboards.

  • Analyze and predict—Understand the current state and predict what's going to happen.

  • Share and collaborate—Engage stakeholders and decision-makers.

Use case: Reality capture reveals insights

For the Badouzi Fishing Port project, the reality capture process resulted in a huge amount of information. To combine the different kinds of information, the agency's team brought the data into a web scene, a representation of the built area and the natural environment around it. Using point cloud data, an ocean data layer, and a mesh, the Site Scan for ArcGIS application was used to display features such as elevation, showing which areas are more vulnerable to sea level rise. Site Scan for ArcGIS is the drone mapping software used for acquiring and processing drone imagery, working with resultant data products, and managing assets.

Further integration with BIM data and the building slicing tool reveals that some buildings have internal construction protecting them from lower amounts of sea level rise, changing the equation for decision-makers and providing a fuller picture. This valuable information can be shared with stakeholders, construction crews, and architects.
