    In this OER module, you will learn about the concept of geospatial digital twins and explore some fields of application. You will create a simple digital twin application using publicly available datasets from the City of Hamburg.

     

    In the practical exercise, you will use:

    • CesiumJS, an open-source JavaScript library for 3D geospatial visualization.
    • CesiumION, a platform for streaming, storing, and tiling 3D data.
    • Real-time water level data from PegelOnline
    • Real-time air quality data from AQICN.org
    • Docker to set up and run our application

    This tutorial is structured as follows:

    • Overview
    • Background
      • The idea of Digital Twins
      • Components of a Digital Twin
      • What is so special about Digital Twins
      • Application Areas of Digital Twins
      • Case study - Hamburg City's Digital Twin Initiatives
    • Practical Exercises
      • Setting Up the Digital Twins application
      • Exploring the Digital Twins application
        • Air quality at different locations
        • Flood Simulation
        • Visualize a Proposed Building
    • Summary and Discussion

    Target Audience and Prerequisites

    This tutorial is designed for students and professionals who want to improve their understanding of Spatial Information Infrastructures, and in particular, learning more about the concept of Digital Twins. This tutorial requires some basic knowledge of geodata and geographic information systems. Knowledge on Docker would be helpful, but is not absolutely necessary as this tutorial will guide you through the various steps of working with Docker.

    You will need about 90 minutes to work through this tutorial.
