Technical Specifications

Requirements and specifications of the handheld (and backpack-mounted) lidar system (including all hardware & software components) are as follows.

The equipment needs to be small enough to be carried in pistol-grip hand-held as well as in a backpack with boom mounted extentions and adaptors, for various above ground suspension configurations, and be operable by a single person, without an assistant.

The equipment must be able to work in hot (up to 50 degrees Centigrade, or higher), cold (down to 0 degrees Centigrade, or lower) and dusty (IP 54 dust and moisture protection rating, or better) field work conditions.

The lidar scanner must also have all of the following performance characteristics to be suitable for USGS field use; range of 100 meters in bright daylight outdoors conditions (or better); total system weight of 6 kilograms (or less); scanner relative accuracy: 1-3 centimeters (or less);

scanner pulse rate of 300,000 pulses per second (or higher). USGS also requires referenced RGB 4K video & point cloud colorization and referenced (precisely time-tagged) input of GNSS NMEA for trajectory to accurately geo-reference point cloud in post-processing.

In addition, the hardware and software Lidar / surveying system must come with the following items; scanner, data logger (incl. battery), main cable, USB3 memory stick containing installation & user guide, shoulder strap (1.5m long), 14.8V battery charger, soft case, specialized backpack frame, V-mount and mounting pole for scanner, kit including all software, 3- yr. software maintenance, pole for backpack frame.
