Sensat, a platform that helps physical infrastructure companies map and visualizes all their data, has raised $20.5 million in a Series B round of funding. Founded in 2015, London-based Sensat is one of a number of so-called “digital twin” software companies that serve construction, mining, energy, and similar industries with tools to replicate their physical footprint in the digital sphere.

The digital twins are built using data garnered from physical sensors attached to assets, wearables, satellites, lidar, and drones, among other publicly available datasets such as traffic.
