Gorrondona & Associates, Inc. Strengthens Mobile Mapping Capabilities with the Pegasus:One

FORT WORTH (August 12, 2014) Gorrondona & Associates, Inc. (G&AI) is pleased to announce the expansion of its surveying and mapping capabilities with the purchase of the Leica Pegasus:One mobile mapping solution. In September, G&AI will be the first company in the United States to upgrade to the new Pegasus:Two mobile LiDAR system.

G&AI serves public and private sector clients including; state and regional transportation agencies, governmental entities, municipalities and counties, consultants, telecommunications, rail, airports, local water districts, state water boards, K-12 and higher education, oil and gas industry, petroleum chemical plants, private development, and power companies.

A complete mobile mapping solution from hardware to post processing – extracting GIS features, to creating digital terrain models; the Pegasus:One captures calibrated imagery and point cloud data and enables processing, visualization, and interpretation through a single, user-intuitive, ESRI compatible software platform. The compact, portable system does not require a dedicated vehicle and can be mounted to an all-terrain vehicle or watercraft. It provides the ability to capture high-quality data at roadway speeds with the accuracy of design surveys and the throughput of asset management.

Unlike other mobile mapping systems, the Pegasus:One requires limited survey control to be set along the project limits—a tie-in to a global positioning system (GPS) base station is all that is needed to ensure survey-grade accuracy.

Advantages

Limited survey control is required (other systems require control set at 600 foot intervals to ensure design quality data)
Ability to create more data than conventional surveys (at 60mph a LiDAR cross section is taken every 4 inches)
Data Reduction Speed (1 hour of drive time = 2 hours processing time (other systems have a ratio of 1 hour drive time = 8 hours processing time)
Portability – mounts on any vehicle platform. Safety – collection at posted highway speeds without risking personnel in traffic to collect road/rail/survey data.

Capabilities

360 degree video capture with 6 cameras
IMU applies 200 corrections per second to GPS coordinates
Synchronized video with point cloud data set
Positional accuracy 2cm horizontally and 1.5cm vertically
Collects over 1.1m points per second at 200 rps (revolutions per second)
Data collected 120 meters left and right RGB video colors can be used to colorize the point cloud data

G&AI is currently using the system on projects for the Texas Department of Transportation, water projects, municipal GIS projects, and electric utility projects. Other applications include design-build services on complex interstate highway projects, where the Pegasus:One can be used to quickly and accurately map bridge superstructures; municipal asset management (GIS); and power transmission line mapping.
