Airborne Topo-Bathymetric Lidar Combined with Thermal Imaging for Fish Habitat Studies in RiversResearchers at Nova Scotia Community College’s Applied Geomatics Research Group have been using the airborne Leica Chiroptera 4X topo-bathymetric lidar sensor for nearly a decade and have surveyed coastal, riverine and lake environments. They have concentrated on mapping submerged aquatic vegetation (SAV). Topo-bathy lidar data of rivers provides an opportunity for improved flood hazard h...
The Canadian government first formally created LiDAR Guidelines in 2017. The document was updated in 2022 to Version 3.1. This session will review the Canadian Guidelines and compare them to the USGS LiDAR Base specification, updated in 2023. Included in the presentation will be:LiDAR for Flood Mapping and funding from the National D...
Canada has just experienced a record wildfire season with devastating impacts. Public safety and damage mitigation is a priority for all impacted by these disasters. From mapping vegetation, analyzing slope stability, planning fire breaks, qualitfiying wood debris and fuel loads, how does LiDAR play a role in meeting post wildfire needs?

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...
