We present an AI-based conversational Digital Twin service leveraging open-source technologies such as CesiumJS and Deck.gl. This service enables 3D map control and geospatial information exploration through voice or text, supporting complex queries and real-time 3D visualization to deliver an intuitive user experience.
In this presentation, we introduce an innovative AI-based conversational Digital Twin service that enables users to control a 3D map and easily explore geospatial information through voice or text commands.
This service combines AI technology with S-Map, a 3D platform that integrates all spatial information of Seoul. It leverages open-source technologies such as CesiumJS for high-precision geospatial 3D rendering and Deck.gl for advanced data visualization, providing a rich geospatial interface.
In the previous of S-Map, users had to go through up to 11 steps using a mouse and keyboard to retrieve specific spatial data—such as apartment rental statistics by district. Now, with a simple command like "Show me the apartment rental transaction statistics by district", the desired results appear instantly.
The service supports a wide range of functions, including real estate search, building design simulation, city comparison, location search, map manipulation, and layer management—all through a conversational chat interface. By combining AI technologies with open-source tools, the system supports complex queries, real-time 3D visualization, and multi-turn interactions—making geospatial data more accessible for users.
