Urban planning and sustainable city development are paramount in our rapidly expanding world. As cities expand and evolve, innovative technologies such as LiDAR (Light Detection and Ranging) are being deployed to address complex challenges. LiDAR is a game-changer in urban planning, offering invaluable insights and data for shaping future cities. This technology is being used to create 3D models of cities and to gather real-time data that allows city planners to make informed decisions about urban development and to create smart cities that are resilient to future challenges.
