SPECIFICATIONS

UAV Lidar Sensor – YellowScan Mapper+, integrated camera and accessories, Cloud-based software, and provided training

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 Class 1 Eye Safe Laser

• Scanner Precision: equal to or less than 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: equal to or less than 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

• Equal to or greater than 240,000 measurements / second (Point Rate)

• Equal to or greater than 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: equal to or better -4 to +104 degrees F / -20 to +40 degrees C

• Weight equal to or less than 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 a minimum of 1 Hours of Autonomous Operation

• Includes at least (2) batteries and (1) charger

• Includes at least (2) USB flash storage drives

• Includes at least (1) GPS antenna and cable

• Payload must be boresight calibrated and provide an angle correction certificate.

• Adapter mount for DJI M600 UAV

• Company based in a non-covered country, as defined by Executive Order 13981

• Includes Cloud-based Software for Post-Processing GNSS and IMU data for accuracies stated above; 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 (CloudStation Core (Color Module, Strip Adjustment Module, Terrain Module)

• Minimum 1 year warranty and maintenance on all hardware and software

• Onsite training or new product installation and training 2 days for up to 4 people
