Surveyors create digital maps or models of the physical world using computer software, a process known as virtual mapping or a digital twin. It involves using computer algorithms and techniques to process and analyse data collected from various sources, such as aerial or satellite imagery, GPS, photogrammetry, and ground-based measurements.
A Digital Twin represents the physical world with a digital model that contains information about its features, such as elevation, terrain, and vegetation. This standard creates accurate and detailed 3D models and other visualisations in various applications, such as digital and hard copy maps for urban planning, land development, and environmental analysis.
A digital twin can also simulate real-world scenarios and test various design and planning options. For example, virtual mapping can simulate the impact of a new development project on the surrounding environment, such as changes in water flow or traffic patterns, and digital design construction inserts developments into the point cloud.
Overall, a Digital Twin enables any professional or organisation to collect, analyse, and visualise spatial data more efficiently and accurately, leading to better-informed decision-making and planning.
