The Canadian Geodetic Survey provides the Canadian Spatial Reference System Precise Point Positioning service (CSRS-PPP) to support clients requiring accurate GNSS information.  The service is used internationally and over 1.2 million GNSS files are now process annually. The CSRS-PPP service has a kinematic mode that is known to support Lidar data collection.  Some recent statistics on kinematic services will be presented and expo attendees are invited to provide fee...

The United States’ National Geodetic Survey (NGS) plans to modernize their National Spatial Reference System (NSRS) in 2025, including adopting a new dynamic geometric reference (the North American Terrestrial Reference Frame of 2022 (NATRF2022)) and a new geoid-based height system (the North American-Pacific Geopotential Datum of 2022 (NAPGD2022)). To ensure continued geospatial referencing compatibility, the Canadian Geodetic Survey (CGS) plans to modernize the Canadian Spatial Reference Sy...

This keynote presentation will revisit some of the fundamentals behind lidar that influence the precision and detail the systems produce. The laser ranging systems that are used strongly influence how the lidar system works and factors including: wavelength, beam divergence, pulse width and pulse repetition frequency will be reviewed and discussed. Most airborne topographic lidars use a 1064 nm Near-Infrared laser, while topo-bathymetric lidar systems deploy both a NIR laser and a green laser...

Traditional LiDAR acquisition platforms are commonplace in the industry and can be relied upon for efficient data acquisition for most relatively flat and uniform project areas. However, when multisource data acquisition is required or acquisition is impacted by complex corridors, excessive terrain, low-hanging clouds or airspace limitations, alternative approaches are required. This presentation will highlight some of NV5’s innovations to address these challenges including the Comprehensive ...
