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...
Flooding is the most costly natural disaster in Canada. Although flood hazard maps are essential for understanding a community’s risk to flooding, in Canada, many flood maps are not always available or up to date. High quality flood mapping that is current and accessible will help governments, communities, and individuals understand flood hazards and to implement effective mitigation strategies to reduce their impacts.Since 2021, Natural Resources Canada (NRCan) has been leading the Fl...
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 ...
AI-driven mapping revolutionizes the use of LiDAR and photo datasets, addressing challenges like underutilized data and the complexity of heavy datasets. By transforming big data into lightweight, accessible information, XEOS offers practical solutions for municipalities and private companies. Through a step-by-step breakdown of the AI mapping process and product demonstrations, attendees will discover how this innovation enables smarter decision-making and brings more value to LiDAR data.
As we navigate the peak of Solar Cycle 25, the geomagnetic storms it brings are more than just cosmic phenomena—they're operational challenges that demand our attention. In this talk, Gavin explores how solar storms disrupt GNSS, a foundational technology underpinning nearly all reality capture workflows, including LiDAR-based field operations. Drawing insights from recent solar events like the Gannon Geomagnetic Storm of 2024, Gavin unpacks the impacts of ionosphe...
We believe that the selection of the aircraft for any aerial collection must be carefully considered. Considerations for type of sensor equipment installed relating to weight and power requirements along with environmental challenges should be taken into account to ensure the safest conditions in all areas.In addition to the aircraft selection, preparing for the challenges for the collection itself will help mitigate the inherent risks that we face regarding airborne operat...
Join us at LiDARCanEX 2025 for an insightful panel discussion moderated by Dr. Tim Webster. This session will bring together experts to explore the current state of LiDAR projects in Canada and discuss what the future holds. Topics include:Wide-Area Topographic LiDAR Mapping: Applications in forestry, flood risk assessment, powerlines, infrastructure, and urban development.Topo-Bathymet...
