The Challenge

Large indoor environments such as airports, convention centers, stadiums, malls, and event venues are difficult to navigate due to complex multi-floor layouts, dynamic operational conditions, and lack of intuitive indoor positioning systems. Traditional static maps fail to provide contextual navigation, accessibility-aware routing, or real-time turn-by-turn guidance across large spatial environments.

The Solution

Developed a scalable turn-by-turn indoor routing and wayfinding platform integrated into digital twin environments for airports, event venues, and smart infrastructure. The system enables users to navigate large indoor spaces through interactive maps, multi-floor navigation, and contextual wayfinding experiences. The routing engine powers Changi Airport's interactive maps and mobile applications, delivering seamless indoor navigation experiences across airport terminals and facilities.

The System

A connected system built for the experience

The experience combines MapLibre, React, TypeScript, Three.js in a responsive system designed to stay clear, fast, and reliable across devices.

The Outcome

A measurable result, designed into the product
