What is a typical scanning pattern used in lidar mapping?

The typical scanning pattern used in lidar mapping is a zigzag or grid pattern. This method is preferred because it effectively covers large areas with systematic overlap, maximizing data collection efficiency and ensuring that the entire terrain or object of interest is accurately mapped. The grid pattern allows for thorough sampling of the environment, which is crucial for generating high-resolution 3D models and achieving precise measurements.

Using a zigzag approach also helps to minimize the chances of missing data points, as it systematically traverses the area from multiple angles. This is important in applications such as topographic mapping, forestry, and urban planning, where comprehensive coverage and accurate representation of terrain features are essential.

In contrast, patterns like circular, linear, or spiral might not provide the same level of coverage efficiency or data density across varied terrains, making them less suitable for extensive lidar mapping tasks.
