Using 3D Scanner for feature surveys is the most effective way of doing them. We have recently completed a primary school feature survey captured by a hand-held LiDAR scanner (Data credit to Mine Survey Plus).
The main goal of this project was generating the 2D Elevation View of a 6-story façade. The challenge of the project was a big tree in front of the building so multiple setups had to be done to get the full details.
The elevation view was delivered in AHD (Australian Height Datum).
