About this file
This document contains brand name specifications for a Light Detection and Ranging (LiDAR) sensor to be procured by the Department of the Interior US Geological Survey Office of Acquisitions and Grants. The specifications include requirements for the LiDAR scanner such as a wavelength of 905nm, precision of 2.5cm and accuracy of 3.0cm. Additional requirements include an integrated Inertial Measurement Unit and GPS, a field of view of 70 degrees horizontal by 77 degrees vertical, and the ability to collect up to 240,000 measurements per second. The specifications also require integrated RGB camera capabilities, operating temperature range, weight, dimensions, standalone battery power, and data storage for one hour of autonomous operation. Accompanying hardware and software must be included to process GNSS, IMU and raw LiDAR data to output a geo-referenced LAS point cloud within the specified accuracy levels. A one year warranty is also required. The YellowScan Mapper+ is provided as an example product matching the specifications.

Brand Name Specifications LiDAR Sensor Specifications:
· Light Detection and Ranging (LiDAR) Scanner with integrated Inertial Measurement Unit (IMU), GPS, and RGB Camera for direct georeferencing and colorization of lidar point cloud (LPC)
· Wavelength: 905nm
· Scanner Precision: 2.5cm – This is measured as the mean value of absolute elevation differences between 2 flight lines recorded in opposite directions over a nadir-located 40m² hard surface area. This specification is the average of three data collects at flight elevations 60m, 90m and 120m AGL. (Precision, also called reproducibility or repeatability, accounts for the variation in successive measurements taken on the same target.)
· Scanner Accuracy: 3.0cm – This specification value is obtained by averaging the accuracy from 3 flight levels @ 60, 90 and 120m AGL. At each flight level, the accuracy is considered as the RMSE value of the elevation differences between targets and the point cloud extracted from 2 flight lines recorded in opposite directions. Validation targets are located within a 40m wide corridor centered along the flight line axis. (Accuracy is the degree of conformity of a measured position to its actual (true) value.)
· IMU Geospatial Accuracy after post processing of 0.02 m – 0.05 m
· Field of View: 70 degrees Horizontal / 77 degrees Vertical
· Up to 240,000 measurements / second (Point Rate)
· Up to 3 Echoes per measurement
· Laser beam divergence 0.28° (Vertical) × 0.03° (Horizontal)
· Integrated 20MP RGB camera for co-collecting imagery with lidar data for colorizing the lidar point cloud
· Operating Temperature Range: -4 to +104 degrees F / -20 to +40 degrees C
· Weight 1.65 kg / 3.64 lbs including camera and battery
· Physical outside dimensions 22.7 cm (Length) x 10.4 cm (Width) x 12.8 cm (Height)
· Stand-alone Battery Power and Operation with no electrical connection to UAV
· Battery Power and Data Storage for 1 Hours of Autonomous Operation
· (2) batteries and (1) charger
· (2) USB flash storage drives
· (1) GPS antenna and cable
· Payload must be boresight calibrated and provide an angle correction certificate.
· Include Software for Post-Processing GNSS and IMU data for accuracies stated above
· Include Software for Post-Processing Raw Lidar data to output an industry standard, geo-referenced, LAS Point Cloud to the accuracy specifications above, individual strips adjusted, colorized with RGB camera data and points classified as ground/non-ground
· 1 year warranty and maintenance on all hardware and software
