Our Software

Covers a wide variety of tasks RiACQUIRE covers a wide variety of tasks present in airborne laser scanning systems. Both, mobile and airborne systems comprise at least one laser scanner, a position and attitude measurement system, and an operator’s work station.
Many systems further comprise camera sub-systems, additional laser scanners, mass data storage devices, and mechanical subassemblies.
The tasks covered by RiACQUIRE are allocated to the operational data acquisition, the phases of system integration, and system verification & testing. An easy to use but powerful interface enhances communication with the supported RIEGL laser scanners. With the aim of reducing the work-load for the system operator, only the most relevant information is displayed and tasks can be executed semi-automatically. Scanning parameters are easily changed by choosing a predefined parameter set. The graphical user interface takes into account the difficult working conditions inside the aircraft, vessel or
vehicle by providing large control buttons, easily pushed even in turbulent conditions.

RiACQUIRE Main Features

• project-oriented scandata acquisition and scanner control
• online visualization of geo-referenced monitoring data during acquisition
• status feedback for fast recognition by the operator
• quality assurance with detailed history of events, system parameters and operator’s interactions
• use of flight plan information for automated acquisition (ALS)

Full Waveform Analysis
Airborne Laser Scanners with full waveform capability digitize the waveform of the echo signal for every emitted laser pulse.
RiANALYZE applies the so-called Full Waveform Analysis to the digitized echo signals provided by the laser scanner and additionally transforms the geometry data (i.e., range and scan angle) into Cartesian coordinates. Thus RiANALYZE converts the digitized echo signal data to data compatible with conventional airborne laser data processing packages for further processing.
The output is a point cloud in the well-defined Scanner’s Own Coordinate System (SOCS) with additional descriptors for every point, e.g., a precise time stamp, the echo signal intensity, the echo pulse width, a classification according to first, second, up to last target.
Additionally, RiANALYZE is smoothly integrated into the project-oriented processing software RiPROCESS via the application RiSERVER.

RiANALYZE Main Features

• full waveform analysis of digitized echo signals acquired by RIEGL LMS-Q560, LMS-Q680(i), LMS-Q780, LMS-Q1560, VQ-780i, VQ-780 II, VQ-1560i, and VQ-1560 II
• extraction of an unlimited number of targets
• coordinate transformation into the scanner’s own 3D coordinate system
• enhanced performance using NVIDIA® GPUs, more than 10 times faster processing

Transforms the scan data into the coordinate system of the trajectory for smooth processing of scan data acquired with RIEGL Hydrography Laser Scanners the Airborne Data Processing Software AddOn RiHYDRO is offered as supplement to RiPROCESS.
When processing bathymetric laser data, additional processing steps have to be applied since both, the laser beam’s refraction at the air-water interface and the lower propagation speed within the water column must be taken into account in order to obtain a geometrically correct point cloud. Those specific processing steps – usually called „refraction correction“ – have to be carried out for each flight strip right after the standard ALS processing workflow.
Refraction correction of the points below the air-water interface (i.e. both points on the water bed and within the water column) requires a geometric Water Surface Model (WSM). WSMs can be generated from the laser data by one of the tools offered with RiHYDRO. An alternative option is to import already existing water surface models. In the first case, the water surface points must be classified before. For this task, a specific point classification tool in RiHYDRO is provided, which allows classifying the points on
horizontal water surfaces automatically.
The user can specify the index of refraction of the water and also a depth bias value to be taken into account during refraction correction.

RiHYDRO Main Features

• Automatic classification of water surface points
• Generation of a water surface model (WSM) based on classified water surface points
• Refraction correction of points below the water surface model (WSM)
• Support of different import and export formats for classification purposes
• Use point clouds from different scanners to identify water surface points
• Import externally generated WSM
• Processes a large number of files for unattended operation in batch mode
• Smoothly integrated into RiPROCESS

Covers a wide variety of tasks Acquiring data in laser scanning with high measurement rates over long ranges frequently results in range ambiguities. Instruments with multiple-time-around capability (MTA), include information in the acquired data which the RiMTA software utilizes to resolve these ambiguities. Instead of requiring users to manually specify the correct MTA zone for each data set or even subset of data, RiMTA automatically calculates the MTA zone for each measurement.
In order to correctly determine the range to a target with a LiDAR instrument using time-of-flight measurements with short laser pulse intervals, it is necessary to correctly determine the correlation of each received echo pulse to its causative emitted laser pulse. At high pulse repetition rates (PRR) and large target ranges this definite allocation becomes ambiguous due to a limiting factor which may not be tweaked by engineer‘s skills: the speed of light.
Today’s RIEGL LiDAR instruments provide extremely high measurement rates as well as long measurement ranges. In such cases, target echoes received may not necessarily be associated with the immediately preceding laser pulse emitted (MTA-zone 1). Instead they may be associated with any of the previous laser pulses emitted. Therefore it is necessary to correctly identify each pulse echo with its correct originating laser emission. This is automatically done by RiMTA in a smootly integrated data proseccing workflow.

RiMTA Main Features

• Automatic resolution of range ambiguity in time-of-flight ranging
• Unlimited number of MTA zones
• Smoothly integrated into the RIEGL data processing workflow
• Additonal note: processes data acquired with RIEGLlaser scanners with MTA-processing capabilities
