Overview

Program-Ace built browser-based 3D urban digital twins on Cesium that combine accurate city geography with live environmental and mobility data, giving planners one shared, current view of the city instead of scattered dashboards.

The challenge

Municipal data was scattered across separate dashboards, with no integrated view of weather, air quality, and traffic. Static reports and outdated maps limited assessment, and proprietary software requirements made any tool hard to deploy across departments.

The solution

Program-Ace built a secure browser app fusing geospatial 3D with live data streams.

A geospatial foundation with Cesium World Terrain, OSM Buildings, and basemaps.
Real-time overlays streaming environmental and mobility metrics.
Analytical features: heatmaps, pollution zones, and comparative timelines.
A scalable architecture for cross-platform browser access.
Live integration with OpenWeatherMap, HERE, OpenAQ, and WAQI.
Technology and approach

How we built it

Built with CesiumJS and React, the twin streams city-scale terrain and building datasets in 3D Tiles via Cesium ion, and overlays live data from OpenWeatherMap, HERE, and OpenAQ, all in the browser so any department can open it without proprietary software.
