Dual Channel Waveform Processing Airborne LiDAR Scanning System for High Point Density and Ultra Wide Area Mapping
Airborne Laser Scanning
visit our website www.riegl.com
The new ultra high performance, fully integrated and calibrated Dual Channel Airborne Mapping System RIEGL VQ-1560i makes use of RIEGL‘s sophisticated waveform processing LiDAR technologyenabling an excellent multiple-target detection capability andMultiple-Time-Around (MTA) processing. The system is capable ofonline waveform processing as well as full or smart waveform recording,resulting in unsurpassed information content on each single target.
The new VQ-1560i provides a laser pulse repetition rate of up to 2 MHzresulting in more than 1.3 million measurements per second on the ground and operates at an altitude of up to 15,500 ft. That allows operation at varying flight altitudes resulting in a wide range of point densities. Thus, the system is ideally suited for aerial survey of ultra wide areas as well as of complex urban environments. By the way, faster and more efficient flight planning and safer flights are enabled.
The RIEGL VQ-1560i comes with a unique and innovative forward/backward looking capability. This enables capturing data from multi-ple angles more effectively and more accurately at high point density. With its large field of view of 58 degrees and its widely variable scan parameters the system enables highly efficient scan data acquisition.
The system is equipped with a seamlessly integrated high performanceIMU/GNSS system. An 100 megapixel RBG camera and the capability tointegrate a secondary IR camera complete the system. Allindividual components are integrated into a compact design and equipped with a mounting flange for simple interfacing with typicalhatches or gyro-stabilized leveling mounts.
• high laser pulse repetition rate: up to 2 MHz
• up to 1.33 million measurements per second on the ground
• offers data acquisition at a wide range of point densities
• two waveform processing lidar channels offering excellent multiple target detection capability
• enables Multiple-Time-Around (MTA) processing of up to 20 pulses simultaneously in the air
• offers online waveform processing as well as smart and full waveform recording
• integrated inertial measurement unit and GNSS receiver
• integrated, easily accessible medium format camera
• prepared for integration of a secon-dary camera
• high speed fiber data interface to RIEGL data recorder
• mounting flange for interfacing with typical hatches and stabilized platforms
• detachable handgrips for facilitated handling
Applications: • Ultra Wide Area / High Altitude Mapping • High Point Density Mapping • Mapping of Complex Urban Environments • Glacier & Snowfield Mapping • City Modeling • Mapping of Lakesides & River Banks • Agriculture & Forestry • Corridor Mapping

The following conditions are assumed for the Operating Flight Altitude AGL• ambiguity resolved by multiple-time-around (MTA) processing & flight planning
Assumptions for calculation of the Area Acquisition Rate• 20% overlap of neighboring flight strips. This overlap covers a roll angle of ±5° or a reduction of flight altitude AGL of 20%.• target size ≥ laser footprint
• effective FOV 58°• average ambient brightness• roll angle ±5°
Definition of the Spatial Sampling Frequency• The Spatial Sampling Frequency is the reciprocal of the 95th percentile of the distribution function of the maximum distances between neighboring scan points. When considering any individual scan point, the probability to find its most distant neighbor within the reciprocal of the Spatial Sampling Frequency is 95%.

The following conditions are assumed for the Operating Flight Altitude AGL• ambiguity resolved by multiple-time-around (MTA) processing & flight planning
Assumptions for calculation of the Area Acquisition Rate• 20% overlap of neighboring flight strips. This overlap covers a roll angle of ±5° or a reduction of flight altitude AGL of 20%.• target size ≥ laser footprint
• effective FOV 58°• average ambient brightness• roll angle ±5°
Definition of the Spatial Sampling Frequency• The Spatial Sampling Frequency is the reciprocal of the 95th percentile of the distribution function of the maximum distances between neighboring scan points. When considering any individual scan point, the probability to find its most distant neighbor within the reciprocal of the Spatial Sampling Frequency is 95%.

Productivity of the VQ-1560i when using a typical aircraft, e.g. a DA42
Very high point densities can be achieved when using the VQ-1560i with a helicopter, e.g. an EC120.
For maximizing the productivity of the VQ-1560i at low point densities an aircraft with a high maximum speed, e.g. up to 330kn, is necessary.
The RIEGL VQ-1560i Dual Channel Airborne Mapping System offers highest productivity.

NOHD and ENOHD increase when using overlapping laser footprints which may be intended e.g. for power line mapping. 8) Extended Nominal Ocular Hazard Distance, based upon MPE according to IEC60825-1:2007, for single pulse condition

9) Limitation for range measurement capability, does not consider laser safety issues!
10) Accuracy is the degree of conformity of a measured quantity to its actual (true) value.
11) Standard deviation one sigma @ 250 m range under RIEGL test conditions.
12) Precision, also called reproducibility or repeata-bility, is the degree to which further measure-ments show the same result.
13) Measured at the 1/e2 points. 0.25 mrad correspond to an increase of 25 cm of beam diameter per 1000 m distance.
14) Practically limited only by the maximum data rate allowed for the RIEGL Data Recorder.
15) The minimum scan rate depends on the selected laser PRR and laser power level.
16) The minimum angular step width depends on the selected laser PRR and laser power level.
17) The maximum angular step width is mainly limited by the maximum scan rate.
