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.

Repeatability*
Based on open sky, GPS+GLONASS processing, and phase differential. Points were
measured manually from within the point cloud. A ring with 26 check points were
collected 4 times, for a total of 104 observations. Check points were measured with
TPS and levelling.
Resulting mean error for X,Y,Z was -0.004,-0.004,0.001 meters, and the resulting
standard deviation for X,Y,Z was 0.011,0.012,0.008 meters.
