Technology is changing faster than we can appreciate. In a few short years surveyors migrated from Total Station to GNSS surveying, the next phase was Photogrammetry, providing an eye in the sky. Altough aimed primarily at 2D surveying the 3D component was exploited to provide a 3D model of the terrain, crude but the progress was a valuable
Introducing LiDAR, this technology provides a mass collection of accurate data, covering under trees as well as the minor details in the landscape.
Expensive? YES! But the old saying is true., “You get what you pay for!”
In one pass the LiDAR collects millions of data points per minute (400 points per square meter). It is fast and it is accurate.
