The smart, resilient, and sustainable future city efficiently and effectively plans, manages andoptimizes land use above and below the surface, and is resilient and safe.

A good spatial understanding of the underground is a key enabler for that future city.

Where will the roadmap lead to?

Planners, land administrators and engineers have timely access to accurate, reliable, and complete information which can directly benefit their work processes.

Surveyors and mappers have the capacity to produce accurate, reliable, and useful information.

A reliable, 3D, digital map of underground utilities will contribute to a spatially enabled future city and will enable professionals to make informed decisions.

A utility mapping ecosystem.
