Various methods can be used to draw 3D mapping, including photogrammetry, LiDAR, and ground-penetrating radar.

• Photogrammetry involves taking overlapping photographs from different angles and using software to create a 3D model.

• LiDAR uses lasers to measure distances and create a 3D point cloud of the area.

• Ground-penetrating radar uses electromagnetic waves to detect changes in soil or rock layers and create a 3D image of the subsurface.

• Other methods include sonar, satellite im...read more
