Advancements in geodesy have shifted focus from traditional surveying methods to more efficient technologies, such as LiDAR. Airborne Laser Scanning (ALS) provides high-resolution spatial data, as well as sub-canopy mapping capabilities, providing a valuable new approach for gathering and analyzing data on land use/land cover change (LULCC). In this paper the integration of ALS data with GIS tools in detection and monitoring LULCC and environmental change are deeply explored. Multi-temporal ALS data supports diverse applications, including erosion assessment, secondary forest succession detection, and urban change analysis. Overall, combining LiDAR and GIS enhances environmental monitoring, contributing to sustainable development and improved resource management.
