Description
The integration of light detection and ranging (LiDAR) technology with remotely piloted aircraft systems (RPAS) has produced new and valuable data sources for analytical cartography. This technological advancement has enabled various applications, including monitoring slope stability and estimating soil movement. This presentation will provide an overview of the techniques involved in planning and running an aerial LiDAR data collection mission and the steps involved in point cloud processing and information visualization. A study conducted in High Park, Toronto, will be used to demonstrate the practicality of using LiDAR data to create high-resolution, three-dimensional maps that support the analysis of micro-topographical alterations in erosion-prone areas. High Park has experienced significant soil erosion in recent years, which has resulted in slope instability, vegetation damage, and sedimentation of the Laurentian River. Off-trail traffic in the form of bike riding, dog-walking, and general adventure-seeking activities have contributed to the erosion. By using LiDAR data, bare earth and vegetation models can be created to accurately map and analyze the changes in the landscape over time. The approaches demonstrated enhance the accuracy and functionality of analytical cartography and can be a valuable complement to High Park’s environmental planning and sustainable management strategies.
