Simultaneous localization and mapping (SLAM) based systems have proved their value for rapid mapping of complex environments, but achieving survey grade accuracy and repeatability has been a challenge in some environments. Surveyors were faced with a compromise between fast data capture and data accuracy, depending on the job requirements.This is no longer the case with Emesent's Automated Ground Control feature, which enhances t...
Use case outlining the challenges, solution and result associated to a Lidar data acquisition using drone and vehicle.
Multi-beam bathymetric surveys are used to gather detailed information about the features on the sea, river or lake bed by measuring multiple depths from a transducer array at high resolution. The result is a highly accurate 3D point cloud representation of the sea floor – similar to aerial LIDAR.
In recent years the geospatial drone market has expanded dramatically. Drone based UAS (LiDAR) and UAV (Imagery) systems vast differences make it difficult to choose one over the other. This presentation aims to explore their differences from the point cloud processing aspect. We will examine the pros and cons of each system for practical survey and mapping applications such as topographies, bare earth, volumetrics, etc. Learn how data accuracy, density, intensit...
A distinguished panel of 3D laser scanning industry veterans will be offering examples of some of their more difficult projects, along with the best practices they applied and the lessons they learned. This will be one of the highlights of the event.

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...
