The Challenge
What the Client Needed
Dodoma — Tanzania's rapidly growing capital — was being planned and managed without adequate spatial data or a unified view of urban systems. City planners lacked tools to simulate growth scenarios, infrastructure teams had no real-time visibility of critical assets, and citizen services were reactive rather than anticipatory.
Our Solution
How TANGIS Delivered
TANGIS captured a city-wide photogrammetric model of Dodoma using fixed-wing UAV surveys, modeled 120,000+ buildings at LOD2, integrated 340 IoT sensors (traffic, environment, utilities), and built a city operations dashboard enabling the City Council to monitor and manage urban systems in real time.

Outcomes & Impact
Results Delivered
Tanzania's first operational city digital twin, now used daily by City Council planning and operations teams
Traffic congestion modeling prevented a planned road intervention that simulations showed would increase gridlock
Flooding risk identified for 340 buildings in a planned development zone — preventing construction in a known flood pathway
Utility maintenance response times reduced by 35% through real-time sensor alerts
