LiDAR Points are often colored by height, with different colours indicating different elevations, making it easy to interpret the landscape.
Subtle differences in the height data, visualized as shadows and highlights, help in identifying features such as embankments, ditches, and others ground variations
Unlike 2D aerial photos, LiDAR provides detailed elevation data, allowing for more accurate analysis of terrain changes.
These measurements create a "point cloud," a collection of millions of precise data points that from a 3D digital model of the highway and its sorrounding.
