| Surveying | |||||||||||||||||||||
| Surveying used to be a time-consuming task, measuring out every single point by hand. Surveyors had to use a system of upright rulers and plum lines at each point, and all the distances were measured using a surveying tape. | |||||||||||||||||||||

| After all of the field work, numerous geometric calculations were necesary to have usable data. LIDAR can be used to streamline the surveying process. A LIDAR set up on a tripod can be used to detect the distance of different points. Often times a surveyor will hold a mirror at the point they want to find the range of. Using LIDAR instead of a tape measure gives the surveyors faster and more accurate results. |
