Leica Pegasus:Two

Mobile Mapping Solution

Asset Management Pavement Assessment

Capturing assets for budget planning and maintenance scheduling, measuring road quality for budget reporting, and maintaining outdoor advertising compliance happens easily with semi-automatic data extraction into a standard GIS interface.

Survey & Design

With the appropriate control points, design and surveying for road construction is enabled at vehicle speeds. Coordinate conversion to local datums is standard and easy even with large datasets.

Rail Georeferencing

Enable quick and precise georeferenced cartography of railways, non-intrusive and safe, enables preventive maintenance while reducing surveying time and balancing staffing requirements.
