The document discusses the development and features of a web-based digital twin platform, highlighting its integration capabilities with CAD/BIM, 3D GIS, and other standards. It emphasizes the platform's open-source nature, accessibility, and real-world applications in fields like shipbuilding and facility management. Additionally, it addresses challenges in smart city initiatives and the lack of widely accepted digital twin standards.

24. A City is NOT a Computer
<Source: https://www.ordnancesurvey.co.uk/business-government/innovation/happens/articles-ehs/smart-cities-digital-technologies>
“Despite the futuristic images the term conjures, a “smart city”
is merely a well-managed city aided by digital technologies.
One of the primary challenges in achieving success for smart
cities, and the reason many initiatives have failed to make it
past the pilot stage, is that they have been driven by a focus
on implementing the technology rather than achieving the
end policy goal, such as improving access to education, or
better transport links.”

25. Overselling and Over-Expectations

26. There’s NO clean DATA
Raw Data Digital Twin

27. STANDARDS?
• Standards are not widely accepted across industries.
“Why should we export our Revit file to IFC?”
“We convert our 3D data to CityGML only because government order to do that.”
• Sometimes data converting lose some part of original information.
• Clients prefer to provide original native format.
• Converting format gives another hassles.

28. What is Your REAL PURPOSE?
