Using missle-targeting technology for 3D city maps

True 3D maps of entire cities accurate within 15cm.

C3 Technologies has developed a way to make explorable 3D maps of entire cities complete with every building and tree. The technology is based on a system originally intended to help missiles find their targets. It uses a set of high-grade cameras mounted in an airplane pointed in carefully calibrated directions. The images overlap to provide multiple perspectives on a single object.

In spite of the fact that this system uses cameras instead of laser scanning, these maps are 3D models accurate to 15cm, not images. The system is not as accurate as laser scanning, the usual method, but it’s much faster and cheaper, allowing large maps to be made 98% automatically.
