- 34. - 34 - Standards and Interoperability 03. Lessons Learned Raw Data Digital Twin • Industry-wide acceptance and establishment of standards are currently lacking. • Standards and interoperability are critical for Digital Twins, serving as 'Systems of Systems' or a 'Federated System’. • Essential to have data or interface standards to construct an accurate digital twin of the physical world. • The absence of standards makes the integration of various domains notably challenging.
- 35. Digital Twins that is NOT Digital Twins 03. Lessons Learned ✓ Lack of a clear digitalization strategy and implementation guidelines ✓ Unclear purpose and application of the digital twin ✓ Excessive use of 3D and emphasis on flashy visual effects without clear objectives ✓ Manual data transformation processes ✓ Focus on visual appeal rather than simulation and analysis ✓ Standalone systems not integrated with other heterogeneous systems ✓ Absence of OpenAPIs and data exchange standards ✓ Lack of measures to ensure data integrity ✓ No clear approach for data processing and analysis <Source: Dr. Hosang Sagong, LH Urban Digital Twins Seminar. July 2022>
- 36. - 36 - Expansion of Digital Twins in Various Fields ▪ Expansion into diverse fields: noise, daylight, odor, traffic, weather, disasters, and ecosystems. ▪ Increasing technical challenges with broader applications. ▪ Significant hurdles in large-scale, real-time dynamic data processing and services. Importance of Standards ▪ Lack of standards for data and interfaces across fields. ▪ Challenges in standardizing data/interfaces for new digital twin applications. ▪ Need for minimal compatibility and standardization to create a "System of Systems." Accelerating AI Integration ▪ Emergence of GeoAI that "understands language." ▪ Various attempts to utilize LLMs such as ChatGPT after their success. ▪ Such technologies may be adopted in smart glasses (Meta Orion, Apple Vision Pro, etc.) Practical Values ▪ Digital twins should deliver practical values by determining how workflows can be completed and applied in real-world scenarios. ▪ Recognizing that building innovative digital twins beyond simply adhering to existing practices and systems is a challenging but necessary process.
