Centerline mapping with Mandli's GPS system is an easy and accurate process that can be
repeated frequently as roads change and expand. As an application of Mandli's road system,
data is collected from a moving vehicle traveling at posted road speeds.
To create highly accurate maps, the data collection vehicle collects GPS data while traveling
in both directions along a route. By averaging the coordinate positions between the
two lanes of travel, centerline maps can be produced.
The GPS system incorporates a high-end positioning system that uses strapdown
inertial navigation, Kalman filtering, GPS, GPS azimuth
measurement and a Distance Measurement Instrument (DMI), to provide position and orientation
data that have a high bandwidth, excellent short-term accuracy and minimum long-term
errors. It provides dynamically accurate, high-rate measurements of the full kinematic
state of the data collection vehicle.
